Vox AC30 Speakers Test: Greenback vs Alnico Blue

[@atishep]

Came for the speaker comparison, stayed for the Excel tutorial.

[@grandesguitarristas635]

Hahaha, for sure!

[@iamamish]

From now on, when I encounter a poorly-executed gear comparison video, I'm going to point them at this video. Amazing. This sets the standard of what a gear comparison video should look like. OP worked hard to eliminate confounding differences between the tone of the two speakers, and showed us exactly what's the same and what's changed. Additionally I like the way OP switched back & forth throughout the comparison, rather than playing for 2 minutes on one setup, then another 2 minutes on the other. It's much easier to compare the tones this way. Bravo!!

[@jalanredop4940]

Totally agreed !

[@anthonybanovic3658]

Sure but not one word of technology spoke. Greenbacks balong in Marshalls. Blues for ACX30c2's

[@IgorHatesEverything]

This is what happens when a competent, intelligent person puts together a comparison video. That was excellent.

[@Kathayne636]

Spot on.

[@tonymarinelli7304]

Agreed, very well done!

[@mladengrubelic873]

A competent, intelligent person doesn't switch on the standby switch immediately after switching the power on. It's not a Kemper or AxeFx. The tubes must warm up to a working temperature.

[@msaintpc]

@@mladengrubelic873 Dumb ass, that was time elapsed. Think first before jumping up to denigrate someone asshole.

[@colinwilliamgraham]

​@@mladengrubelic873 Tube amps existed for years before standby switches were added, and there were no problems just turning those amps on you moron.

[@bierce85]

thank you so much for switching back and forth quickly! wish all demos did this

[@Willtext]

One of the best speaker comparison videos I have ever watched! Thank you for taking the time to make it 👍🏼

[@renno92music69]

Watching this 6 years after you posted it. What a brilliant demonstration between the two amps. Perfectly done. I’ve played a greenback but never a blue. This has given me the answers to get a blue. Thank you

[@marka7519]

I have several of the Vox AC handwireds in various power sizes, and all are equipped with the blues. I too have often wondered how the blues and greenbacks differ in these amps. This is just an excellent demo all the way around. I can appreciate the production time that went in to making this. Add bonus points for slipping in MS Excel. While I still prefer the blues for what I play 90% of the time, your demo makes me think I wouldn't miss them too much if I had greenbacks, and the higher gain was clearly better to my ear with the greenbacks. Although when I play higher gain through my blues, they sound just fine to me as well. Thanks again and keep up the good work.

[@MaxSoloMusic]

hey, thanks for your feedback. Yeah, both are great! I personally would go with blues, they sound much more traditional in terms of AC30 to me. But even with high gain they have some unique spiciness

[@alexmurphy5289]

@@MaxSoloMusic I agree. I think overall unless you’re constantly running your vox hot with high gain the blues are the tone most are searching for. Greenbacks are in tons of other combos anyway might as well go with the blues in your vox right?

[@lifeofalex9199]

By far the best speaker comparison video I’ve ever seen. Perfectly executed

[@agreen182]

This clearly took a lot of effort, and is extremely well done. Thank you! I bought an AC15 and replaced the greenback very easily, I'm surprised to find I prefer the normal channel sound of the Greenback but the top boost blue speaker sounds a lot better to me. Super interesting video!

[@SuperZiggyCraft]

I really appreciate how you kept playing while switching amps, so it was really easy to tell the difference. A lot of people take a long time to switch and talk in between, so you lose the sound of the amp in your head. Overall this was a nicely laid out comparison. I personally based on the video prefer the sound of the the Greenbacks.

[@1mlb704]

To me the Greenbacks sound better for the thrashy stuff, but everything else sounds better with the Alnico Blues. This was very helpful, just ordered an AC30HW2X, thanks for the video!

[@Calagamberr0]

Lol. Tell me you didn't

[@Mojokiss]

I just got the AC30HW2x with english greenbacks

[@kuhtipp]

Some of the rare VERY GOOD comparison videos on youtube. Thx

[@gliddofglood]

As far as I can hear, not enough sonic difference to justify the price difference. Sometimes the Greens sounded better, sometimes the Blues did. Depended on the guitar, the mike and the distortion. I think one could be happy with either. I have an AC30 with Greens and wouldn't start a Blue hunting project on the basis of this video. Excellent vid BTW. Very complete and well put together. Thanks!

[@davidfield8122]

gliddofglood yeah, I think the average player would be better off saving the cash on the .05% tone difference and buying a few awesome pedals with the savings instead. Plus I hear the blue speakers don't last as long

[@keithspillett]

The blues have a lower power rating, so I could imagine people blowing them apart without too much trouble. My band hosts jam nights, so I've installed much higher rated speakers in my amp, because many of the jammers choose to turn everything up to 12!

[@jagjet9153]

Wives are a thing of joy, right up until they say no ! Having said that if you can see, feel, smell, taste or recognize a difference in a product, then it is a value judgement. When wives are involved with financial dealings then the smartest thing to do is provide a bauble, or practical solution or equal value for her. Let's realize that her set of valuation parameters are different from yours. How much does she spend on a Hair appointment ? How long will the difference pay for your gear ? This a just one item. How about clothes ? This is about you getting more than her in her eyes. So you must balance this with factual parity. Make it equal for you both and "Happy wife equals Happy Life". If you are not really equal and even handed shame on you, this woman picked you and she didn't have to. You had nothing to do with it. She knew she could fix you !

[@tonymarinelli7304]

Your comment is brilliant, some who are lucky enough NOT to be married may not fully understand.

[@lifeofalex9199]

I think the price difference in the speakers is related to the cost of the magnets they use in them not the sound quality

[@jordanpratt3821]

Jesus I went through so many videos before I found this one.Had I found it first it would have been the only one I needed. Great job.

[@charlfrick8245]

The Blue went better with the top-boost channel, but in the normal channel the Greenback sounded great and less boxy than the Blue. Nice work Max.

[@B3D5X]

That's what I thought too!

[@atomicrocker]

Exactly!

[@euro9115]

Thanks for providing the comparison video. I have a buddy that keeps telling me to upgrade the greenies in my AC30C2 to blues. I realize Alnico magnets are superior but I really didn't hear 'that much' of difference to warrant the expenditure. I'm 65 and my ears just aren't what they used to be. I just bought an AC10C1 with a creamback (should be here this weekend) - looking forward to comparing the two amps. I know I'll be happy with the +/- 45 lb. weight reduction.

[@Failons89]

Fucking hell this was the perfect comparison video!! Quick swap with no distractions, Fender and Gibson clean, then up to the highest gain, different generes, clear graphic help, all in 8 minutes!!!! Please do more

[@TheWarriorSongProject]

For those who do not know how retail pricing works, I will explain. I am not endorsing or applauding this, I am just explaining (I worked for Avid and M-Audio). Retail Price = Cost x TheMultiplierNumber. Wholesale Price is usually 50% of the MSRP. Minimum Advertised Price (MAP) = some fraction of the MSRP that is usually fixed, like 80%. In one of the companies I worked for, TheMultiplierNumber was 5. So, if the Cost to build a widget was $100, then the MSRP would be $500, and the Wholesale cost would be $250. If it cost $200 to build a Knutenvalve, then the retail would be $1000 ($999, for the psychology) and the wholesale would be $500. This is why the cost of the alnico blue speakers isn't exctly 308 euros higher than without. The speaker changed the cost of build, which drastically affects the multiplier (and often, the profit margin).

I choose greenback, more balanced. Blueback has more presence at crunch, especially top boost. Thx bro, excellent work.

[@tmuka]

i preferred the more mid focused green tones in this excellent comparison. It did make me wonder if adjusting the tone stack to find the sweet spots for each speaker may have highlighted benefits overlooked with a flat tone stack. of course that's a lot more variables to track! thanks for the video

[@gordontubbs]

Greenback for gain tone. Blue for clean tones. May as well put 1 of each in the amp! Best of both worlds.

Wow! Thank you for your research and that your doing this in English it’s helping me immensely with my decision to purchase one of these amp. Your insight, research, and use of common resources to find information is impressive. Tausend dank!

[@SamuelOceanMusic]

Excellent demo! I have both an AC30C2x (Alnico Blues) and a recently acquired AC15HW1 (Green Back). I'm loving the mid-range crunch I get from the GB on the AC15 but after seeing this video I think I might swap it out for one of the Alnico Blues on the AC30 and see what happens. Thanks again! Cheers.

[@gerardootero4364]

Samuel Ocea How did it go?

[@pfmusic1636]

I recently just bought a used Ac30 cc2 from the mid 2000’s. Came with alnico blues. I’ve tried a lot of vox amps of the years. This is the first one I actually like. I say give the blues a try. It’s the classic combo.

[@sassulusmagnus]

Thanks for the demo. There's a noticeable difference in the sound of these speakers when used in a traditional style 6 input non-master volume AC30 such as an AC30/6TB or TBX. The Blue has a more pronounced upper midrange response. Together with its lower power handling capacity, this allows the Blue to translate more of the amp's chiming sound at lower volumes. The Blue gets the "blizzard of nails" tone better than the G12M25 Greenback. The Blue is also audibly louder than the Greenback at lower settings. But the volume difference disappears as you turn the amp up, and the Greenback lends the amp a more focused sound as you push the volume. The Greenback never gets unattractively ragged sounding in the highs at loud settings as the Blue sometimes can. The two different speakers make a great sounding mismatched set with an AC30.

[@cgavin1]

This! The blues lose all definition when pushed. Just turns to mush. Chime is nice but most modern Vox amps are way too icepick to begin with.

[@ix-Xafra]

The Greenbacks sounded richer to me. This video helped me decide on the speaker for an amp build.

[@davidmerlin3344]

They both sound great. You cant go wrong with either speaker.

[@aitken1965]

This video earned a "subscribe"! EDIT (4 years later) I finally got an AC30C2X! I found a great used one and I jumped on it. This video still stands out as one of the best demonstrations of the amplifier’s capabilities.

[@ZoogieBAR]

Brilliant video editing skills! Great production. The Blues have more upper midrange punch and the Greens are slightly more "scooped".

Watching in 2024. Great video and one of the best comparisons I’ve ever seen and not just music gear but for any product. I recently bought an AC15C2 with Greenbacks and was curious how they would compare with the blues. While they do sound different each had their strengths but I wouldn’t say one was better than the other overall. I’m perfectly happy with the greenbacks and the blues don’t sound THAT much better to justify the price difference of upgrading

This is an excellent video. Switching from one speaker in an instant playing the same riffs made it easy to tell the difference. And showing at the top all thru the video made it so you can go to any spot in the vid and know what your hearing. Thanks for posting. So many people swear by the Alnicos but the difference to my ears is minimal and not worth paying for.

[@antonioalbares]

Great comparison. THey are both great speakers. I use Greenbacks in all my amps. I actually like how dynamic alnico blue is, gives you that sweet clean tone but when it comes to gain, the woody rock sound of a greenback speaker is unbeatable. If you are lucky enough to have one of each, why not. In reality, there is no better or worst, it depends how you like your tone to b. I also like V30s for rhythm guitars.

[@alarimbaud3155]

It's interesting (to me) that so many people seem to prefer the greens for overdriven tones and the blues for clean tones. For me, it's the reverse. The greens seem to have a more open sound, and sound great clean but get a little muddy/too warm when overdriven; the blues sound more compressed, and thus stiff when clean, but really articulate and defined (not at all muddy) when overdriven. But yeah, amazing comparison video. Unexpectedly helpful!

[@QerstyBass]

I feel the same! The blues have a stonger midrange and not as wide treble response so i makes for awesome rock n roll overdrive tone. I feel it compliments the scooped character of the amp better too

[@littleglimmer2325]

Good vid. I'm not looking to drop a fortune on blues now. While there may be small differences in A-B comparisons (and personal preferences),I always remember that when gigging in a band with other instruments, vocals and audience - nobody's going to hear the subtleties of £000's spent on speakers that close in sound.

[@bojackhorseman5367]

Great comparison - I have a pair of JMI era AC30s, one which has non-original Greenbacks (serial number dates them to late 1969 - so those are post-JMI, probably came from a Marshall cab or something), and another with the original blues. This is the same kind of difference that I hear, really - the one with blues has a much wider spectrum of sound but with quite a soft, smooth character to how it projects the sound, the top end is very sweet, the bass is kinda loose but not in a muddy/flabby way. By contrast, the one with greenbacks has a kind of dirtier quality to the sound, much more direct with a more focused and punchy midrange character. Both sound glorious, though. It really depends whether you want the more angelic, airy sound of the blues, or the more aggressive, focused sound of the greenbacks, as to which speakers you should go for. I love both, but for different things.

[@ratterec]

Great job on the video. very helpful!

[@monkeyxx]

great demo! helped me a lot

[@amritjanardhanan]

First of all, amazing comparison! Here's what I heard: Blue's cleans were fuller w/ more mid range, less of a "nasal" tone. Liked them better than the greens. Blue's "crunch" tones on the non-top boost channel were really full, sounded almost like a Marshall! Green's crunch tone were not nasal, but retained top end-clarity better than the blues. I liked the blues better, but greens weren't bad. On the top boost channel, for some reason the Blue's had more treble, but also were not as clear - sounded more "vintage" whatever that means... Greens didn't have the filter effect or top end of the blues. I liked both, but they were very different. I noted more clarity with the condenser mic compared to dynamic mic. I liked the condenser better in every situation.

[@plaidretinas]

Was going to switch my greens to blues.....not anymore.

[@pericabenic4413]

You have to get the VOX AC30 with the Alnico Blue speakers to believe it. I did not believe it until I tried.

Blues add a ton of midrange. Not what you want unless you play cleans or a really ice picky Tele imho. Humbuckers especially the neck on a LP can become impossibly boomy.

I love greenbacks for Marshall JTM-45 circuits. But with an AC30, the Greenbacks sound like you threw a blanket over the cabinet (until you get to the very high gain, then you hear why the greens are better for Marshalls). All the stock Vox amps come with Blue Speakers made in China. So the best deal is to buy separate UK/English Blue Alnico Speakers (lightly used if possible to have them broken in) for a better value and better speakers (with even more complexity to the mids than you hear with these Chinese units). Sell the Chinese Greenbacks, or keep them as backups... or for your next Marshall. GREAT test video! You can really hear the differences.

[@jaysigma]

Well, I kept heading for a Vox Amp in my mind and followed some of the threads online. With that video is all said and done! Great comparison, dude! Best of information stuck into short time! To me the green speakers had a better "definition" in sound, the blue ones are a bit more "brown"... a bit mellow. Is it worth the price changing then? I think it will depend on the gear you're using, your style of music and all these tiny little things which use to have impact on your sound. There is no right or wrong... just make YOUR decision what seems to be matching to you. To me, I would go for the greens. But what do I know? Just my penny.

[@kurtweiand7086]

This was a good test, 😊 thanks. Put one of each in a duel speaker amp!

[@masque1313]

Well done video. Straight to the point and shows what you need to hear. Both speakers sounded great but they were different. Really depends on just what your ears prefer. I lean slightly to the blues.

[@johndennis9838]

Thanks for that! I was wondering what the greenbacks sounded like in the AC30, as I have the ac30c2x. But let me tell you. With this amp, it does not sound good at all (to me) until you get the master volume to at least half way up. The whole character of the amp changes completely. Much more harmonically rich, the whole bottom end comes up in a big way a really nice grunt not buzzy preamp sound but full power tube sound and much more touch sensitive. A different amp altogether, night and day. But this amp is very, very loud at that level. I installed a power scaling circuit in mine(VVR)that works great, so I can set the master where I need it and tame the volume by regulating the voltage going to the power tubes. Still very loud. Much better than an attenuator though. I love the Alnico Blues. To me they make it sound like a Vox. But it's very distinct so I could see the Greenbacks working better in a cover band situation where a variety of tones are needed. Thanks!

[@MaxSoloMusic]

Hey, thanks for feedback. Yeah, unfortunately I wasn't able to capture them cranked all the way up. It would be a shame to move out of my apartment because of that :) The difference is much bigger on higher volume. I agree, Greenbacks sound somewhat modern and more versatile to me. While Alnicos make the amp sound like a Vox that we know from records, vintage in a way

[@johndennis9838]

Yep, you have to have the right environment to crank them up.

[@twezzo99]

[@shader26]

Thanks for this! Other comparison videos had me unsure, but to me the greenback sounded better in almost all, even clean. Clean the blues did have more “presence” (not meaning treble type, actually a little darker and bigger) but in a band setting I think the greenbacks would cute better, and we always have boost, or upping vol changing amo eq. I also play often on the edge between clean and dirt where digging in on the string brings out more od, and for that I’m now decided that greenbacks are the way to go for me. Thanks again! Really well done video!

[@jagjet9153]

Excellent and fair test ! the only trouble is the quality of your effort is defeated by a wide range of limitations. 2 inch Computer speakers, poor sound cards, tone stacks in sound cards, well I could go on but I think the answer is obvious.....This is in the ear of the live buyer. Having heard the amps live, I can tell you there are subtle but important differences. Can you hear the difference in tone of a Vox amp played on 120/60 AC versus 234.0 volts at 50 cycles/second. That makes a huge difference. To 99 people in a hundred there will only be a perceived difference, not a measurable one on an oscilloscope. In all fairness the riffs played were close but not identical in all variations. A tone generator would have been a better comparison.

[@sorazmasterofdoom]

Awesome demo, thanks! I love the Alnico speakers for cleans, but with any gain the Greenback speakers win.

[@georgeoliverdavidthalman1091]

for the difference does internal adjustments i.e setting bios, parts for the outputs etc. maybe effect pricing?
