Sound Dropout from your guitar amp - fix it fast!

[@McRaeStudios]

Good day. It is 7/15/2023. I purchased a Vox VT100 that fuzzed out. I purchased it cheap probably because of that. I was on my way to do something drastic and then I saw this video. I had a short 90 degree pedal cable and connected the send/receive jacks in the back. You are absolutely correct. I will never use the loop jacks so the cable will remain. I now have full volume all the time. Maybe I will try the cleaner though. Thank you so much. Correct Information is powerful.

[@kurtmccracken3394]

You just fixed my Magnatone super 59 sprayed a little cleaner In the loop connections now i’m back to the great sound I know and love thanks

[@jamelectronics]

Glad I could help

[@DuelingDragonsMusic]

This was so helpful! It’s been an issue with my Marshall DSL40C, and now doing good so far. Such a simple fix. I was dreading having to take it in for expensive diagnostics and repairs

[@mariomariado]

Same here! I will try this ASAP!

[@adam__mark]

Did it work for you guys? Mines been doing this for years..

[@adreenalize]

My problem is that I lose volume when I use the effect loop... For years I plugged a Boss GE into the effects loop to boost my solos, but suddenly when I press the pedal I lose volume.. a lot of. If I switch the amp off/ on the power comes back. I use a DSL 2000 50 watts. Can anybody help me?

[@marcmeyer8910]

I never would’ve thought of this on my own. But it makes so much sense when you explain it. It was sure a lot easier than opening up the amp and tinkering around. Thanks for the simple fix.

[@miketeeveedub5779]

I ran the pre-amp external output of my Marshall 8040 to its main amp external input and voila! Problem solved! No more clipping and fade-out! Thanks for providing us with your knowledge!

[@bigshuff]

Just bought a Marshall Valvestate 40 amp off ebay it was 1994 version with original box pristine condition got is unpacked and you guessed it the sound faded out! My little heart sunk, what can I do? Get on KZbin and see if there is a solution ..... Thank you my friend worked a treat Ill give it a good clean with some electric cleaner now or buy a new fitting.

[@ripkingston]

HOLY CRAP THIS FIXED IT. My Marshall did this almost since I bought it back in 2004, I would clean everything out and it would seem to fix it. I even brought it to shops and they didn’t know what was wrong, they would just clean everything and it would work again. The problem came back today after 7 years and this fix was perfect.

[@jamelectronics]

I love it!

[@rustynales4597]

This man is a freaking genius. Wish I had know this years ago lol

[@andywerle8464]

Just bought a used amp that appeared to be in great condition and worked great when I was testing out at the previous owner's house. When I got back to my place and started playing with it, the signal "buzzed out" as you described a few times. Flipping it on and off standby fixed the problem in the short term, but I was understandably concerned about my new purchase. Then I tried this solution while it was in "buzz out" mode, and the signal returned right away. Thank you so much! I should get around to cleaning/replacing the effects loop jacks, but this fix is wonderful.

[@jamelectronics]

Andy, thanks for your feedback. I'm so happy my video helped you get your amp working properly!

[@songwriterscove4515]

​@@jamelectronicshis story is my exact story to the letter, only 5 years later. Thank you so much, it saved me from ripping the speakers out of an amp I just paid $240 for to try and salvage it. (Vox ad 120 VT)

[@Malletman12]

My man, you just gained a subscriber. Wow...I've been fighting this one for a couple of days and was getting ready to take it in. Found your video and it's been playing absolutely clean for about 45 minutes now. Thank you!!!

[@ix-Xafra]

Great observation. This is a common issue and the contacts in the jacks are the culprits.

[@elomars12]

I planned my whole weekend around the repair of my amp and it was this easy fix, thank you

[@LonesomeGhosts]

Replaced my tubes, changed my cables, etc. Nothing was helping... until JAMES SAVED THE DAY! Thank you sir!

[@KonwTheTrut]

I could’ve spend hours browsing forums for this info or I could’ve watched this. Seriously, thanks for your help on this one, friend.

[@jriff79guitar]

I just fixed my Bugera 1990, thank you so much James!! That explains why the output transformer was working so hard, because of the resistance in the FX loop. Transformer is staying cool and the amp is running great. Very helpful!

[@jeffhuxford2870]

Just fixed mine as well!! Thank you!!!

[@ChayBode]

Took mine apart and noted some the jack pins were loose so cleaned them and push them back into place and no more drop out, very happy now😀😃😁

[@mattwarren6116]

After years of pulling my hair out with this old Peavey bandit 112, you have discovered the problem! Thank you sir.

[@FilthyIcon321]

Dude same. I came here to say I have this problem with my peavey bandit 112.

[@RobertLaurie011269]

Wow, thanks so much! I have a 30 year old jcm600 marshall replaced tubes and was so puzzled thinking power drop off meant a power tube problem. Not my old Marshall friend and I can get on with things until I get a permanent fix. Much appreciated!

[@nickwilson7572]

GC30 Laney lives again. Patch cable worked instantly. Thanks for sharing.

[@sideparting6845]

I changed all my valves and this was the problem! Thanks! Solved it just patching the effects send to return.

[@27retrodaze]

Man, thank you!! I bought a used Peavey Supreme XL (solid state) head and shortly after i started having volume loss issues to the point where it was unplayable and I got the recommendation to patch the effects loop and it worked perfectly! But I couldnt find any info anywhere as to WHY that works... I much appreciate this video!!!

[@jamelectronics]

Glad it helped!

[@69bigmuff]

Just like to say thanks,you’ve just fixed my old Laney 65 bass amp,really appreciate it,all the best

[@jamelectronics]

Very glad I could help!

[@mxvet7477]

Wow! Thanks for the tip. I had the same issue & I pressed the loop bypass button & the problem went away! Splawn quickrod 100

[@randyburke8324]

James, Thanks so much ! I just fixed by Peavey Prowler, and you saved me some $$$ on a repair bill !!!

[@swangonzalez4797]

Thats exactly what I did whahahahah. Just had new tubes installed and the amp cuts out. I read somewhere that effcts loops jacks go bad over time, and cuts the signal. If you plug into these jacks they may not return to the bypass position and remain cut off becuase contacts are dirty or the spring doesn't want to come back to the proper position. So the signal gets cut. And I figured what if.....I patch a cable into this. Lo and behold the problem vannished. Looked online for a video regarding this and found this. Thanks for the confirmatory info James. This fix will save you a costly trip to your tech.

[@vwsurfer2003]

Excitedly, I tried this to no avail. That said, I took the circuit tray out of my amplifier and turned it over. I found that a resister had come loose in the solder connecting it to the board. I reflowed this solder and added a touch. Now, all is good. Thankfully, mine was a easy fix. (Amp: Marshall MG50DFX combo)

[@fickdenalgorithmus3251]

Got the same amp and Problem, hopefully my solution will be as easy too :D got to find time to open it and check everything. your comment gave me hope

[@BrianWCole]

Thanks a lot James. I ran into this when re-tubing a Marshall JTM 30, and this bypass loop keeps input signals very consistent and I haven't heard anything since from the musician. So thanks for the reminder since I just got in a 1980's Roland Bolt 60 with the same reported issue. You saved me a lot of angst!

[@itenbitten]

My Marshall 2553 is back! Thank you so much. I was about to replace tubes. Thank you, James!

[@motorrebell]

By plugging in a Patch cable in send - Return loop ( Never used the effects loop ! ) , It definitely solved the "Drop out -volume " & Noise problem with my 10 year old SOLID STATE Amp ( Hughes & Kettner - Edition blue ) ! Seemed those send-Return inputs were heavily corroded ! THNX !

[@jackjackattack9137]

That is what my problem was, thank you sir ! Put a patch cable in and its working. Ill change the jacks when they arrive. Thanks agsin !!

[@BassMcNasty]

I have been bashing my marshal amp to get it to work every time I use it... this tracks with this problem. Can't wait to get home and try and bypass the effects loop!!!

[@GlorifyGodInEverything]

wow lol. If only I knew haha. I've been pulling my hair out trying to figure out this issue. For once, I found someone who had an answer!! You are the man my friend.

[@jamelectronics]

Glad to help!😀

[@lorencing]

Thanks, just what I did on my PRS MT15, replaced the FX loop jacks ... worked like a charm.

[@adamjscarborough5600]

Worked for my Ampeg SS-70, thanks!

[@rogerc3484]

Amazing!!! I got a Vox AD60VT amp from 2001 year, that was completely dead with no sound! I plugged in a guitar cable into the Loop effects Send and Return.....and it now everything Works just like New!! Even the foot controller pedal. Unbelievable! Amazing! THANK YOU! So much Sir!

[@Hendrix77SRV]

Thank you so much for this video!! I've spent months trying to figure out what could be the issue and finally it worked like magic! I was just about ready to throw my amp out the window as the local tech could not remedy it. Thank you!!

[@richarde5718]

Genius, going to try this on my old Crate 60w tube that's been cutting out. Thank you

[@titopaeng]

I’ve done a lot of diy fixes to save my amp except spraying contact cleaner in the input jacks. My amp doesn’t have a send/return, but tried the fix on the main input, the footswitch input, line out , and headphones outc and it worked! Crackling and sound dropping are gone. Thank you!

[@josevega042994]

Thank you so much! i just plugged my cable in and out of the efects input and out, they were just a bit dirty

[@KidThomsonMediaProductions]

Seems to have worked on my Marshall MG30DFX thanks

[@manuymagoxx]

OMG TYVM MATE YOU SAVED MY LIFE I have a rocktron rampage rt122c, it has 2 speakers and sometimes the volume dropped suddenly to almost 0 in one or both speakers and this solved my problem, thank you very much. You should definetly try this if you had this problem before

[@Venemoth666]

Mine rampage r80 also have this problem

[@seekbreath1]

Man this made my whole night! My Blackstar HT Stage 60 has been down for over a year now and that just brought her back to life. Didn’t work on my Marshall DSL40 Vintage but that might be a preamp tube. Thank you for this video!

[@JeffB-hf9rb]

Oh wow damn. I've been having these kind of problems. I have a sonic maximizer going through my effects loop. Thank you sure! I haven't tried it yet, but this gives me hope that when I sober up I can fix this.

[@johnsimms3957]

Since I don't use my effects loops I tape over their jacks with electrical tape. I figure this will keep them problem free.

[@getchapull3111]

Thank you so much James.! I thought my Randall Rg100 classic head was a lost cause. It was just sitting collecting dust for the past 10 yrs.

Thank you sir, you have saved me. I just bought an amp yesterday after testing it in the ex owners house, where it worked just fine, but had this issue when i got home. I thought it was a voltage problem in my apartment or that i may have damaged it on the way. What a bummer, until i found your video. Thanks again, the least i can do is subscribing to your channel, so there you go.

[@anthonysthellhammerg4388]

What really sucks is that the guy that sold it to you obviously knew of this issue and he didn’t say a word besides “O hell ya it’s great it’s awesome “ I hate dickheads like that , Well my head just started doing this so I ain’t gonna lie I’m scared 😟 even though I make three times the amount of money when I bought my set up well you know i ain’t gotta tell you about the hear and now that you already don’t know your self,Man I hope this works just I hope I have half the luck 🍀 you did pray 🙏 🙏 haha sorry about my problems didn’t come here for that just saying that guy had to know ,I mean how could he not ,ya know

[@JPAcuna3]

@@anthonysthellhammerg4388 Yeah he must have known, and when i told him what was happening he just said "thanks for the information"... buying used things sometimes is such a headache. I ended up selling that amp and bought a new one. But instead i did tell the new buyer about this and gave him a patch cable to close the loop in case he wasn't gonna use it.

Great tip, thanks for sharing I usually replace parts as I have an electronics degree and don't mind soldering. But that is an excellent way to troubleshoot the fx loop section 👍

This worked on my Marshall 5210. I ran out of contact cleaner but have some on the way. I cleaned the pots today and will try cleaning out all the inputs. The amp has a bit of static going on but a cable in the effects loop prevents the cutting out and volume drop like magic.

I just want to thank you so much for this advice. I had an old Marshall jcm 2000 dsl 100 that I stopped using years ago because of the volume fading out intermittently. I replaced all preamp tube sockets and resoldered everything in the amp, thinking it was a cold solder joint but nothing worked. Finally I had to purchase a newer version of the dsl that in my mind is sub par to the original. I just found your video today and tried your solution. It worked wonderfully and I’ve been playing for several hours now without any issues!! Again, thank you so much for this advice!!!

I’m sure that could be why an amplifier with an effects loop could misbehave, but there are far more issues other than an effects loop jack that would trigger this problem. Power tubes, preamp tubes, output transformer, etc… etc… etc…

[@trevorbest5715]

You are right but as seen from other posters they had looked at these potential issues you refer to and it hadn't solved their issue. This potential fix should be your first port of call. Its a quick fix and cists no money. Never overlook the simple things otherwise you could spend a lot of money and be no further on.
