HOW TO INSTALL A MASTERY BRIDGE: Installation Guide PLUS Setup Tips on a CME Jazzmaster

[@guitarz]

honestly it just doesn’t get any better then videos like this. Man if you bought and sold modded offsets I buy 3! but im sure your repair/mod list is growing by the day. Puisheened offsets!!!

[@vicdelapaz]

I would ABSOLUTELY sign up for that!

[@mikeschneider2251]

Mike, I hope you're happy, healthy and safe. These are some of the best videos ever made. Thank you.

[@JP-jy7sk]

I recently purchased a brand new American Vintage II Jazzmaster and immediately purchased a mastery bridge along with their thimbles. To my surprise, the stock thimbles fit the mastery bridge perfectly and I decided not to replace them. Another huge surprise- the mastery bridge was delivered set up for a 7.25” radius and the intonation was dead perfect. I literally did nothing beyond adjust the action height after installation. Wow!

[@THEItchybruddah]

Mike, once again you’ve saved me. Yesterday I finally installed my Kinman pickups in my Jag, with MUCH guidance from a genius builder pal. But, the process whacked out the setup and intonation. Thus you helped me revive my ol pal! (Also, if anybody is scouring the interwebs to know the SIZES of the Mastery hex wrenches: * 1 .050″ allen wrench (small) * 1 5/64″ allen wrench (medium) * 1 3/32″ allen wrench (large) Godspeed errybody!

[@jasoniversen7124]

This is the video I've been waiting for. I have a mastery bridge on order and I've been scouring you tube for installation tutorials. There isn't one video that even comes close to this. Thank you! You are scholar and a gentleman!

[@MrWillington37]

Incredibly helpful, I considered installing my Mastery myself but I wasn't confident enough so I went to my local tech, but this video would have been absolutely perfect! Cheers Mike!

[@Adam_underscore]

I’d love to see your full review of this model. The CME player JM seems like one of the best options for getting into offsets, and offset moding.

[@bartonbishoff]

Be sure and remove ground wire that is routed from pickup to bridge post. At 4:28, when you drill down, you will hit the ground wire if you don't move it. Heads up on that. When you install new post, then you can reconnect the ground wire.

[@FFFreq333]

I've never even thought to lube the strings at the saddles... I've been playing for HOW LONG NOW?!?! Thank you as always for your wonderfully informative videos!

[@treblehelix7200]

I just got a Halon aftermarket bridge to replace the TOM on my classic player jag. Stainless steel with chrome plated brass saddles

[@basicmitch6078]

The shot at 6:14 helped me immensely in knowing where exactly I needed my bridge height. You said that 3mm is about perfect for the mastery. I've found that to be true! I'm working on a CV Jag right now and I wonder.. since you said the stock bridge is set higher. What is the proper height for the stock bridge? I'm guessing around 1/10 or 3.5/4mm. I can't seem to find anything else online with an answer. Thanks for doing everything you do!

[@devinpatrickmusic]

Super helpful! I’ve got a Mastery on my Jaguar and Jazzmaster and shimmed the neck bringing the string angle way to high. Resetting the shims and Mastery height makes for a much better playing experience! Thanks Mike!

[@padernia4477]

this was the video i needed to see! TY Puisheen! I have both Jag and Jazzmaster that ive been setting Mastery bridges on. Each instrument is different but you addressed the issues i was looking into. Once again, TY, and i appreciate all the effort you put into educating us on the offset world.

[@padernia4477]

ive not drilled my guitars but have the mastery posts... im afraid of doing so. i dont experience any rattle issues currenetly... is that ok? lmao.

[@Puisheen]

Some models don't need drilling, it really depends on the model

[@padernia4477]

​@@Puisheen ive been able to pull the original thimble's out but its not the same size as the mastery thimbles. that being said i have no problems currently so why fix whats not broken? the Jag is positioned super high though... maybe removing the neck shim.. Once again, youre amazing and kee[p up the good work!

[@timsullivan2381]

How do you go about grounding the bridge/trem system? Do you have a ground wire soldered to the tremolo? I'm building a partscaster jazzmaster. I'm using a Jazzmaster bridge and trem. The body is predrilled with a hole to the bridge thimble hole, I was thinking about just running a bare wire through that hole and leading it to the thimble, so when the thimble goes in it will make contact with the bare wire. The other option might be to solder to the trem somehow, but I'm not sure that's possible for me to get enough heat into the trem to make that reliable.

[@benmtz]

Wow! Thay lip balm tip is smart 🙌🏼

[@trentonortgies1754]

I’ve had my mastery bridge for 6 years and couldn’t figure out why I couldn’t get rid of fret buzz. I knew I had to be missing something. Turns out I missed the Allen wrench key hole within the Allen wrench key hole to lift the whole bridge. Thank you for this video and blowing my mind.

[@davidwood351]

I also have a shell pink JM from CME. Waiting for my time to change the bridge out. I just might try the CuNiFe pickups too.

[@maxpeck4154]

I have a MIM road-worn Jazzmaster that I just bought new a couple months ago (my first offset). I bought the Mastery vibrato and it's absolutely killer but SO FAR the strings have stayed put on the stock bridge. I believe I read somewhere that at some point Fender moved the vibrato forward slightly (1/4"?) to allow for the same jig to be used to make multiple models. My bridge height is darn close to where you suggest with no neck shim and I think the break angle is just right. No issues so far. Excellent video!

[@analogkid8]

Mike made a video about vibrato position! kzbin.info/www/bejne/nai2g3pqeLSAb68

I do enjoy the stock bridge, and if it's working you're good to go!

[@hutch5359]

[@bradrock7731]

Outstanding! It's time to choose a bridge for my Jag parts pile & was concerned about my Warmoth neck with the compound radius. I have the Mastery in the cart. But was also looking at the modified mustang bridge Warmoth sells.

[@nicholaschavira1743]

Hi Mike, How much should we shim the neck? I see stew mac sells shims pre-made, is there a particular thickness you recommend? Thanks!

[@jefferybacus9406]

Wow I really wish this video was around 6 months ago. I paid a "luthier" to install the mastery into an AM Pro JM and it looked like the guitar on the left at 7:42. He argued with me that it needed to be that way and it was a whole ordeal.

[@Puisheen]

Oh noooo did you ever get it corrected? The original Pros have a two degree tilted pocket which is way, way too much. I often have to 'reverse shim' them (I think I mentioned that in the video) to reduce that angle for Mastery Bridges

[@jefferybacus9406]

@@Puisheen Sort of. After weeks of going back and forth with him I finally had him install the reverse shim despite his protest. He actually thought the correct break angle was significantly higher than the neck angle would have even forced him to go. It doesn't really stay in tune very well, he blames the shim and the low break angle for that and says its my fault for making him lower the bridge. I think the tone might be a little bit muddied but that might just be my ears playing tricks on me. I honestly think he was so offended that I questioned his expertise that he probably just threw the shim in and didn't even bother finishing the setup. I need to take it to a new luthier that knows Jazzmasters. Wish you lived in NY lol.

[@Artefracture]

Wow, the saddles on mine were slammed to the front and bridge was really high up. Thank you! PS - is the pinky Jazz getting a gold guard?

[@Puisheen]

I really want one of these bodies for exactly that purpose, but sadly no!

[@drewdemaio4162]

The video I've been waiting for! Thanks!!!

[@drewdemaio4162]

I set my bridge at 3mm height and still feeling like my saddles are a little high. Certainly higher than Pancake's. I feel like this guitar could play better but not sure what more I can do. Neck relief looks on point and the neck is shimmed. It's a Troy Van Leeuwen JM. Any thoughts Mike?

[@matttorres8921]

Can I add to measure the depth of the thimble prior to drilling! It may seem like a no-brainer to not go super deep with the drill press, but I think we all know a story or two of a time where someone (sometimes even ourselves) should have measured before doing a mod.

[@The_grik]

[@robertbodle2354]

that was amazingly precise, acute, and articulate - after all the precision and technical lowdown, however, i wanted some more kick ass play through. but good stuff. certainly reference grade!

[@myyt4382]

Thank you Mike for bringing all these points! Just a question considering that I have stock bridge which is looking exactly like 7:40 (left) - how to determinate if the break angle is too much? Or bridge height? I assume there is some maybe rule of thumb measurement or something to watch out. Also it's not clear to me what exactly is the downside(symptoms) caused by that bridge/angle too high. Tuning issues? rattle? Pickups that cant go enough high..I would be very thankful for the answer! Maybe also idea for a short video as I believe this is an critical aspect of offsets. Thank you very much in advance!

[@Puisheen]

The stock bridge does require a healthy amount of neck pitch to work as designed. If your bridge is working, it probably has enough angle.

[@williambebeau1506]

You sir, are an absolute god! 😂😄❤️ I've honestly been in dire need of some of this more detailed information in regards to mastery setup for quite a great deal of time now, having not ever been able to find all of the answers on my own, despite my best efforts.

[@johnthelad]

Hi Mike, would I have have any problems fitting a Mastery bridge to my new Pro 2 Jazzmaster? Is it the same as your CME .Would I need an M1 kit? Thanks John.

[@Puisheen]

Usually I do recommend the M1 Kit for modern Fenders as the body thimbles can vary a bit in size, but the Mastery fits tightly in mine. Do note that the Pro 2 has an angled pocket so you may need to reduce neck inclination for the Mastery to perform its best

[@johnthelad]

@@Puisheen Thanks Mike, very helpful.

[@DoNoise]

What do you think about the original vibrato and the bridge of this JM model?

[@Puisheen]

They're fine. Middle of the road parts, nothing fancy. Surely would have needed loc tite on the bridge screws, and the vibrato felt just alright and was relatively noise-free

[@xtheory]

Did you find the need to shim the CME Jazzmaster? I just ordered one!

[@CW0123]

Would it be too much of a hassle to put one on a guitar that has a strat style trem?

[@michaelscammon731]

Great video. And timely, since I'm in the process of building my own Warmoth JM. Question though, at 7:22, can't this be corrected by just lowering the pups, instead of shimming the neck pocket? Those pups look pretty high, compared to the 61.

[@Puisheen]

The problem at that timestamp has nothing to do with the pickups. American Original Jazzmasters have a factory-angled neck pocket that in my opinion is pitched back a little too much, which is why the bridge had to be so high to achieve playable action.

[@jasonp9373]

Puisheen at the 7:18 mark you said that reverse shimming or shimming the neck pocket of an American Jazzmaster/ Jag Original can be beneficial. What degree of shim do you recommend if you are going full pocket reverse shim or shim the head stock side only? Would the "thick' side of the shim go towards the head stock side of the pocket? I've been trying to setup my JM American Original. Thanks!

[@Puisheen]

If you're adding a Mastery, yes it can. I would recommend using a .25 or a .5 depending on your instrument's unique string geometry, and yes, the thick side would be pointing toward the headstock!

[@jasonp9373]

@@Puisheen Happy to report that the .25 shim in the pocket in the reverse configuration totally works! I was able to get more of a string break/pressure on the Mastery bridge and lower the action a bit. That coupled with the hammer trick on the vibrato bar, beaten lightly into submission, it has never played better.

[@0826man]

Beautiful CME jazzmaster. Thanks for the informative video. Hoping i get to own one.

[@tendingtropic7778]

If the mastery bridge works best if its between 2-4mm above the pickguard, then how do you set the string action (I'm used to set the height of the bridge as high or low as needed to get the best action)

[@drapps4443]

Help me Puisheen! Tired of fighting with my MIJ Mascis Jazzmaster… how do I know if I just need a shim or a mastery bridge to really make the playing more enjoyable? I can’t seem to get the action low enough… is it the mismatched radius between the neck and TOM or neck angle?

Come on Mike! You are definitely a national monument, a Jazzmastery pusher! Thank you for existing!

[@astrovenus8345]

Amazing vid- i was hoping you were going to address dialing in the string height with the master bridge. Im finding it tenuous, trying to exclude acoustic buzz but retain an ideal action. Its not happening. By the time i get rid of acoustic buzz (striving for cleanest tone possible) ive lost the edge on the action. Please help! My luthier has already done a 2nd neck adjustment. Im playing with the fine adjustments but the overall allowances just dont seem to be aligning 😢

[@JakeMakely]

Do you have any guides for the different bridge upgrade options? I have a fender pawn shop series offset special that came stock with an AOM

[@ThatMattGoodMusic]

Great vid as usual! However I thought the point of the JM vibrato is the saddles rock with the strings, does the Mastery not do that, hence the need for lubricant?

[@Puisheen]

The Mastery is a fixed (non-rocking) bridge by design, so lubrication does help

Hi Mike, I can see that the bridge is rocking a bit in your video. Is this to be expected? I thought one of their main advertising points was that the bridge stays in place. I took my new Fender Japan Traditional 60s Jazzmaster to a luthier who installed a Mastery bridge and vibrato. Today I noticed that the bridge is rocking a bit when I use the vibrato (also some of the strings go a bit out of tune afterwards). I checked the parts box the luthier gave back to me and noticed that that he did not use the thimbles that went with the M1 Mastery kit. The bridge seems to rock inside whatever thimbles are there. Would it still be the case with the Mastery thimbles, or are they flush with the bridge feet? Is there any point in asking him to replace and install the Mastery thimbles? Thanks for your advice.

I did call Michael at Gryphon Music ( He says hello and said what a Great Guy and Friend you are) and that they have 2 skilled Luthier's that know the Jaggs and Jazzers' in case I need a set up and string change or a tune up from time to time.

Hello! Just found your channel. I just got a TVL jazzmaster with a mastery bridge. I’m a bit new to mastery and adjusting my own guitars in general. It plays great. The radius looks perfect and there’s no buzzing. The neck looks very straight, but the action is slightly high on the higher frets. Should I tighten the two screws just a hair to bring it down ever so slightly?

[@Puisheen]

First I'd take some neck relief measurements and see how much you've got in the neck. Lower the bridge via the screws embedded in the posts (loosen) and re-evaluate!

[@garyp5522]

Great Video. I have a question I hope you will answer. I have a J Mascis Squire Jazzmaster. Now I can not afford a Mastery bridge for this guitar but can do a staytrem. With all the jazzmasters you have set up and played do you think the Staytrem bridge would make this guitar feel/play better? Thanks

Just curious, how is it possible to get correct intonation on 6 strings when there are only 4 adjustment screws??

Exactly. Some amount of compromise is surely the case is some situations. My Staytrem has individual adjustments for each string so I don't have to worry about that.

@@justonemorepedal4466 yea it seems strange. They’re highly touted and $$$ so I would think you could intonate them properly but it does seem funky

It's totally possible! Remember that intonation is a function not only of saddle position, but saddle height, curvature, neck pitch, and the overall height of the bridge. There are a lot more factors at play than just the tilt going on, and that's how you do it!

[@42069G20911Boobz]

The mastery seemed to change the tone of the guitar and the feel of the vibrato a little bit on my A.O. 60s jaguar. Not good or bad. Just different. I thought the mastery was fuller and more balanced, the vintage style bridge a little plunky with more character and a different low-end (unhelpfully subjective I know). Mastery might have the slight edge if you want to make a Jaguar your main guitar, but the vintage bridge was maybe more interesting as another "color". I couldn't quite get the mastery to stay in tune, probably because I have always been somewhat mechanically challenged. When pulling up on the trem, the tuning would go WAY sharp while using the mastery. The mastery was definitely moving/rocking a little bit too. I'm sure it was user error, but I went back to the vintage bridge (works fine with Mastery thimbles) which seems a little more idiot proof, and is actually very tuning stable using 12-54 D'Addarios (actually using 11-52 now, perfect, made a small truss rod turn) I also managed to strip the screw head for the mastery bridge post. Oh well. If the luthier/tech I used to go to comes out of retirement, I might try to have the Mastery bridge professionally installed. Conclusion: mastery is cool, but wouldn't buy it ONLY for tuning stability. And if you REALLY suck at mechanical guitar stuff like me, make sure you know a guitar tech who understands offsets to help install it.

[@CW0123]

I always heard they (mastery) stayed in tune but at the same time I’ve heard people can keep fender offset trems be it jazzmaster or mustang in tune too.

[@42069G20911Boobz]

@@CW0123 So I bought the mastery thimbles and everything, but when I pulled up on my jaguar trem the tension would almost pull the whole bridge and everything would be a little sharp. I was using 11 - 52 strings. I started to have issues with the stock bridge too (not tuning issues, but rattling) and now have a staytrem which is great. I still have hopes I can get the Mastery working eventually, and assume I just need to get a set up by someone who knows what they are doing as far as offsets, which unfortunately is not the case with a lot of otherwise competent guitar techs.

Hi Mike, what height (mm) above the pick guard would you recommend for a Staytrem bridge? Think mines far too high

[@Puisheen]

The Staytrem bridge is great and still requires some height to do its job well. Normally I just install them in place of the stock bridge with a proper setup, so whatever works for the guitar.

[@myyt4382]

I have same concern..how to determine too much 🙃

[@anthonyfarias3632]

Hey, great video! I have an American Original Jazzmaster and I have a few questions. Do I need to replace the thimbles to fit a Mastery bridge? If so, will I need to drill the holes again? Also, what Stew Mac shim do I need for the neck?

[@Puisheen]

Fender thimble manufacturing can vary, so it can be a good idea to get the M1-KIT with thimbles. As for the holes, I've gotten away without in some cases, but it's a good idea to keep the drill handy just in case. Shimming itself depends entirely on the guitar, and with the AO you'll have to reduce neck angle to get the best experience from the Mastery. Grab the three shim set and experiment

[@danielpetrzelka1460]

Mike - do you often/ever document the heigh of the strings over the body or pick guard as part of your setup measurements? (rather than the individual building blocks of neck shim, bridge height and action) Wondering if you've found an ideal range?

[@Puisheen]

I haven't, no. The distance from string to body isn't really my main concern during setup, it's really all about the neck angle and bridge height

[@247Boredable]

I wish Mastery would offer the brass saddles they use on some of their tele bridges for their offset models.

[@twseve]

Just picked up one of the new Fender American Professional bridges for JM, and it does not fit my MIM JM. The posts are ever so slightly wider than the stock bridge. Any idea as to whether the Mastery MT thimbles will allow the American Professional bridge to fit without having to fill and re-drill thimble holes?

[@dogit5988]

I have a VC Squier Jaguar. Thinking of getting the Mastery bridge. Worried about having to replace the thimbles with this mode. Typically are the Squier thimbles replaced with the larger Mastery bridge thimbles? You show how to do this, however how do you do the “the fill and drill” procedure discussed in this video? Maybe you have a video on this process and I haven’t seen it. I am retired and I am tired of paying my local guitar tech for stuff thanks for the guidance, your transfer of knowledge is greatly appreciated.

[@veitchy88]

For fill-and-drill, you get some dowel the same diameter as the original holes, put them in the bridge holes with a bit of wood glue and cut them off flush with the top of the body. You now have wood to drill new holes into. This is common for converting from a tuneomatic style bridge. For CV Jag, the bridge specs are nominally the same/similar to American/vintage specs so a fill-and-drill shouldn't be required. At most, you may need to slightly enlarge the holes, but you can do a satisfactory job of that with a hand drill or drill press running in reverse.

[@Puisheen]

CV, you shouldn't have to fill and drill.

Hi Mike, thanks for all the great and entertaining videos. I've really been enjoying them. I have a question. I have a MIJ Jazzmaster, probably from about 1994, or so. I don't remember exactly what year it was I bought it. If I purchase the M2 Mastery kit will I have to do any drilling to install it? I'm trying to avoid that if possible. I'm a little confused by the description on the web site and am not clear from your comments in this video. Thanks

The M2 has a second set of wider posts which should fit whichever thimbles your Jag happens to have. The interior diameters can vary a bit but you should not have to drill anything

@@Puisheen Great! Thank you for the reply and the information. Cheers!

Mike, I’m building a Jaguar. Do you think a 10”-16” compound radius neck will be an issue with string buzz and intonation?

[@chrisst8922]

It's a funny looking thing. I noticed it the other day on Shermy's Creature. To me a bridge is a bit of steel with a groove filed in it that the string sits in. But this thing looks like some bit off the T101. All those screws and bits and pieces and the strings fit between the posts not on top of them. And the guides aren't all the same, it could be 5 blocks with screws between the strings and then a little block at each end but this has 4 blocks with screws and four little blocks without and it looks like Mr Mastery ran out of bits when he was making it. It's just the kind of thing where it's own fokelore will develop. A master of the Mastery.

Hey Mike, love the videos. Question for you, what do you keep the action at on your Jazzmasters? 5/64 at the 17th? Always been curious...

I love this channel and I truly do appreciate all the work Mike puts into these videos. I have learned a ton from them. But this is the only thing that I truly disagree on. Why is it that people pay $200 for a bridge that has so many complaints and issues? A bridge that needs videos (like this one) on how to set it up because of all the issues people have with it. I am baffled. I have many Staytrems (that cost about half as much as the Mastery) and I install them myself. They are easy to set up and they work perfectly and made of high quality stainless steel. They solve all the issues that people have with the stock bridge. There is zero maintenence and zero glue needed. You almost never hear a complaint about the Staytrem and no setup videos are needed. I just don't understand why anyone would shell out $200 for something that you have to have training to set up and maintain. I am truly baffled.

This is such a weird response. People pay for things they like, but if they don't know how to properly install them, that's where complaints come from. That's who the video is for, of course. Do you understand that this kind of work may not be as intuitive for others as for yourself? Just because a bridge pops right in -- Staytrem included -- doesn't mean you'll never need to do any adjustments ever again, or that every aftermarket bridge will just pop on and play perfectly. I repair offset guitars for a living and I hear as many complaints about Staytrem as I do the Mastery, the RD, literally every other bridge out there. There are good and bad things for all options, but the idea that every guitar is the same, that you need zero knowledge to perform this task is, to use your own words, baffling. It's the exact same argument I hear all the time from people who can't understand why I'd play a Jazzmaster over some other guitar that doesn't require specialized setup techniques. Bonkers

@@Puisheen I don't expect people to be intuitive that is why I recommend a Staytrem because it is easier to set up and understand. The radius is already set. You set the height and then adjust the intonation for each string. As long as there are no other issues with the guitar, that is it. It is beautiful in its simplicity. There is no crazy having to work out the relationship between radius and intonation to get the intonation properly set. That kind of stuff takes a lot of experience (that you have, but that most people don't). Look, I am not against the Mastery. For some guitars (compound necks, etc...) absolutely need the radius to be adjustable. But when I spend more money I am hoping that it makes my life easier. Maybe other people want to pay for the challenge. I don't know. I don't have as much experience as you fixing guitars, but I have spent a lot of years helping people solve problems in a bunch of different groups. Issues with the Mastery (mysterious buzzing, saddles sliding, loose screws, etc...) happen frequently and I can only remember one Staytrem issue in the past three years. Maybe something else accounts for that disparity but even my friends on the boards with Mastery's would not say that there are equal complaints for both. Anyway, this is something we both feel passionate about and your experience is different than mine. I do really appreciate all your hard work on these videos. I frequently refer people to them to help solve issues. I do hope more people discover your channel. Peace.
