How does the BadCat BlackCat compare to a Vox?

black cat and matchless _c30 are better than vox to my ears plua they give you the choice of 12ax7 or ef86 front ends in the sane amp

wonderful class a goodness

Who would choose an AC-30 over Fender or Marshall?

Not me, never.

What's so great about the AC-30?

I honestly have never seen/head the allure. I've never thought the Vox sound was all that spectacular. Fender does better cleans, marshall does better grind. I can appreciate others liking that tone but I've no use for it personally...it's like drinking a glassful of maple syrup to me...sickly sweet. IF I want jangly british cleans I'll go Hi-watt.

I agree with GEARJONESER

I will also add that the BLUE ANGEL sounds muddy to me in prog linkage mode. I prefer the EL84s, but the lower mids, EQ reaction of the amp, and reverb (which is nice) aren't quite an AC30. Mesas all sound like Mesas to me, certain recipe they have.

AC30s are very "mini Marshall" to me. Many techs agree EL84 have a mid signature in the vein of EL34s. The bottom end is softer. The tube rectifier on a AC30 also sounds sweet esp when pushed, for SAG. You can run an AC30 and MArshall together and sound great, as this guy named Slash has been raving he finally stumbled onto. I think they have sweet cleans in the AC30, however, the Class A saturation, while harmonically rich, is not as ROCK n Roll to me as a Marshall (yeah yeah, Brian May and all that - but it's not live Gary Moore, Hendrix, Page, Beck as far as balls out tone) Btw, a 50 watt marshall has a much sweeter sound. I am assuming you mean the 100w Marshall in general discussion here.

yeah, I agree with you about the progressive linkage 6V6/EL84 together thing on the Blue Angel. I used to run it in that mode to get a bit more clean headroom at certain gigs, but it wasn't my favored setup.

Dan Hawkins of The Darkness runs AC30s with Plexis and sounds outstanding. His brother's triple recto tone sounds like background interference in comparison.
 
Re: Vox AC-30 Lovers

One question that didn't get answered, unless I missed it: Was the AC-30 the first EL-84 amp or was Marshall the first to use EL-84's in a guitar amp?

EDIT: In terms of guitar amps: Is class A vs Class B an over-rated argument? Class A sure seems to be a lot harder on tubes than Class B.

Class A vrs AB just have a different feel to them. I love both! And, I'm not worried about tube life. If the tone is there with a hot biased fixed bias design, i''ll replace the tubes more often if I need to.

Changing tubes in an old AC30 is a real mess... I can't understand why Vox chose to do it that way. The tubes are placed behind the chassis, so you practically have to take out the whole stuffing (expect for the speakers and reverb tank). Idiotic.

the new ones are the same way
 
Re: Vox AC-30 Lovers

Different strokes for different folks. I've always really liked that Vox sound. The cleans are amazing, and when pushed, I'd take the OD Vox sound over a Fender any day.

As Olin said, Marshalls are different beast altogether. I've always been slightly dissapointed by Marshalls (stacks, combos) whenever I try them in stores. I love the Marshall tones I've heard others get, but I don't think I'll ever own one. It's like that whole 'guitar having mojo' deal. To me, Vox and Fender amps are more responsive, and enjoyable to play. If I go heavy-disto styles, I'd much prefer something like a Mesa or Engl.

And about the whole Class A or A/B thing: It's a pointless debate. Because of the nature of the term, Class A just sounds more impressive, or like it would make your amp sound better. A and A/B are just different, and both give you great sounds.

Fender amps are usually taken as clean amps and older Marshalls only sound great when you can really crank em up...Everytime I've plugged into an AC30 I've felt it was just always too bright and too jangly for my tastes,but this was at lower store volumes....Maybe it was actually a reissue AC30TB though? I've dialed in some really great sounding AC30 tones in my Vox VTH and for me it's adding a bit more low end balls and some mids to the tone...Almost Marshall like I guess the way I dial up the AC30 tones..

VOX AC-30 is still not A but a hot A/B.

Is that right? The AC-30 is not a cathode biased amp? I thought it was. The Matchless Chieftan and C-30 are cathode biased...I thought the Vox AC-30 was too. I know that technically a true class A amp would have only one output tube, like a Fender Champ, and that what most call class A is not true class A. But I thought the AC-30 was at least cathode biased like class A amps seem to be. Maybe I'm wrong... Lew

Thought Class A was really all about bias swing.....
 
Re: Vox AC-30 Lovers

Vox AC30 (and the more popular top boost model) uses a Class AB power amplifier design, with the valves biased "hot", so while this operates in class A at lower levels, it is a class AB design. There's no negative feedback in the power amp either
And some more.
The Fender and Marshall designs use class AB for their output designs, biased with the valves almost off with no signal. This is more efficient (more watts per tube), and better for tube life. When you play, tubes take turns handling each half of the signal. This leads to some (unwanted) distortion as the tubes cross over. Class A designs are rare in medium to high power guitar amps, but true class A has the tubes operating at half power, with no signal applied. When you play, the tube fluctuates between full and no power, so there is no switching to add unwanted distortion. This is a very superficial explanation; please read elsewhere on the Internet for more detailed descriptions.
