I gave up on the Fender blues Jr. as it had a tad bit of background hum, and sounded too sterile imo.

I've taken a liking to Roland JC-120 and Vox AC30. There are however problems.

The JC-120 has good tone and all, but doesnt have the tube life-ness (as its a SS). How can I add tube life-ness without getting tube squaky-ness, fizzle, and pop, etc.?


Also, the Vox AC30 breaks up too easy.

I had it set at the following:
volume (or preamp, rather) at around 40%
master volume (or post amp) at around 30%

for a 30W that should be about half-driven, right?

for clean, I set it at:
volume (preamp) barely even on
master (about half-way

it still had break-up at this setting as well.

any suggestions?

Are you sure you were using an AC30 and not an AC15? AC30s DO NOT, repeat, DO NOT break up too easy. There is no way an AC30 was breaking up with volume "barely even on" or "around 40%." AC30s are known for high headroom. And anyway there are two settings in the back of the amp that allow you to change the break-up rate. Either setting, however does not allow the amp to break up at 40%.

You may have been playing an AC15 which does break up quicker. Try an AC30. The main thing about them is they play clean at high levels. What guitar and pickups were you using?

If you want to add some life to a JC120, add chorus and use a clean boost pedal. That makes it completely come alive.

If the Blues Junior was too sterile, you won't like the Roland JC's. Those amps are MEANT to be sterile.

I was using an AC30, it was the 2x12. I think the speaker cone may have been messed up or something. 'Cause yeah, it should have ALOT of headroom.

Like I said the JC-120 had good tone just not enough oomph (such is the nature of SS).
I may try using an external tube preamp with it. *shrugs*

The other shop has an AC30 also. Theirs is probably in better condition than GC's.


Btw, I was using a Schecter Ultra straight into the amp. No effects.

What the hell are you talking about, AC30s are built to break up. 4-5 on the master volume is usually when tube amps start to break up.

TS, try setting the amp up for a good overdriven tone and then roll your volume back for cleans.

AC30s are built to break up. Wow, now I've heard everything.

Uhhh, these amps were originally built for The Shadows. So you think distortion and overdrive crunch is what The Shadows were needing way back in 1960. Good Lord.
And now in 2009, you feel the good folks at VOX have turned the AC30 into a high gain monster that breaks up when the volume is barely on.
Unreal.

"AC30s are built to break up."
You may want to check that theory of yours out a bit.

any tube amp is supposed/forced to break up once the tubes get saturated - when it happens depends on the tubes and the circuit
you have to consider the times the shadows ordered the ac15-twins as they called them - those vox amps didnt have any master volume, so they could crank them up more until they got distorted - afaik even the master volume in the circuit decreases headroom a bit
if you set the master that low, your amp's gonna break up - turn it up! but dont blow your head off

Whodicted

Yeah, it's a 30 watt tube rectified amp, what do you expect?

Well, the amp they used and the AC30s of today aren't exactly the same thing

Oh, because it breaks up easily means it's a high gain monster? Seriously, what are you talking about?

Your exact words (in all their hilarious glory):
"AC30s are built to break up."
The key words being "built to break up."
Of course any amp will break up, my little acoustic Crate amp can break up if pushed, but what you are saying is the AC30's reason for being is break up. You said they are "built to break up." That, my friend, is about as sane as saying the AC30 is built to be waterproof.

Word of advice -- if you have no knowledge of something, don't add your two cents. Your two pennies here are useless.

I never thought I could ever read something so ridiculously wrong.

They're not literally built to break up, but they're certainly not known for MASSIVE HEADROOM like Twin Reverbs. More headroom than AC15s of course, but that's not saying that much. And no one said AC30s are high gain metal machines.
#17


I'd say AC30s are fairly middle of the road as far as headroom goes. They sure are loud for 30-watt amps.

Is that all you have, some poorly chosen words? It's a figure of speech my friend.

AC30s may not have been designed back in 1960s to break up. That doesn't change the fact that they do break up quite easily and certainly don't have the "high headroom" of which you speak.

If they have such high headroom why did vox release a 50 watt and 100 watt versions?

Look, you came on here with these nasty words" "What the hell are you talking about?"
And then you followed that up with this doozy: "AC30s are built to break up."
Word of advice:
If you are going to respond in a nasty manner, you'd better not follow it up with hilariously stupid words like "AC30s are built to break up."

I'll forgive your initial nastiness, but it is impossible to forgive your stupidity.
"AC30s are built to break up."
Why someone with such little knowledge would come here and be nasty is a mystery.

It's a figure of speech dipwit.

Lack of knowledge? You claim AC30s have high headroom, could you be more wrong? You keep coming back to the same thing, maybe respond to the rest of my argument?

There's a reason he was put on the list. Don't go claiming that he knows nothing.

Casino, you need to relax. I know AC30s weren't MADE to break up, but IMO, their best tone comes from it being cranked to the point where it breaks up quite a bit.

AC30s have massive headroom, that's why Brian May uses them.

You want clean headroom buy something like a Fender Hot Rod, you want raunchy breakup then get an AC30.

Uhhh, "massive headroom"? I see you have to lie. Find where anyone said that.

By the way, AC30s have a switch in the back where you can actually increase your headroom. You didn't know that, huh?

Jesus, Allah, Buddha and Jewish God.

Kevin - AC30s do break up, yes. But they're just as well known for their clean tone as their breakup. Why do you think REM used them even on their early albums when they were mostly playing clean? I've played many AC30s and I can safely say that you need to crank them pretty focking hard to get them to get their breakup tone, and you know how loud they are. If you keep the gain low, at anything below small unmiked gig volumes you won't get a hint of breakup out of an AC30.
And BTW, the AC50 and AC100 aren't higher wattage versions of the AC30 - they have a different tone.

CasinoEpiphone - No need to be a knob. AC30s are designed both for cleans and for that crunch tone, which is why Brian May and Peter Buck (two very different guitarists, at least pre-Monster Buck) both use them.

CE: In your first post you claim the AC30 has high headroom. Massive headroom, high headroom, same difference.

Shadow: I know about the AC50/100, I was just being a smart ass.

I never said they didn't have good cleans o.O All I said is they break up easily, they're practically (better?) built to break up (note, it's still a figure of speech). My blues jr. has good cleans, doesn't mean it has high headroom or that it doesn't break up fairly easily.

My AC30 didn't have that switch..must have been a dud. All I know it was a raunchy, gloriously loud bastard of an amp. Not particuarly clean, not horrendously dirty either....barked like a junkyard dog when you hit the low E and the speaker cloth jumped a foot.

"High" is such a boring word, massive is a much more exciting...synonyms ftw.

Believe me, Kevin isn't a fool - he's forgotten more sh*t than most of us know.

I wouldn't go so far as to say that they were built to break up, or built for cleans. I think they were built to achieve a happy medium, which no one can deny that they do. They're one of the few amps which I would use both for cleans and for gain - the only other one I can think of is a Fender SuperSonic.

Yeah, that's a good way to describe it. It doesn't have those crystal clear cleans (which I think the TS is after), but more of a dirty grtty clean.

When you say British cleans, you think AC30, just like you think Fenders when you say American cleans. That is my final word on the matter.
