I'm using my Studio with the master high and the gain low for clean tones. I'm getting a lot of hiss. Do you think this is this tube related or something else? Any suggestions for driving the snakes out of my amp?
 
My 22+ is the noiseyest of my 3 Boogies. Strangley, it's noiseyest in the CLEAN channel. I have read that this is a by-product of the odd pre-amp input stage that they have. :cry:
 
I believe I've read that, too. And I agree that the preamp topography is a little odd. You'd think thay would have put a pot in to control the lead gain stage. I might have to experiment a little.
 
here's an e-mail a tech sent me about the (original) Studio 22...I don't know if any of it applies to the "+" models

you wanted to
know about the design flaw of the
Studio Boogie. I am talking about
the original Studio, not the .22+

This has a voltage divider as the
first thing the guitar signal is
fed into, and this is so bad
design from an engineering view
that I wondered why they ever did
this.

This causes increased background
noise level (hiss).

The reviews of the amp in magazines
all complained about the higher noise
level as compared to the Mark Series
amps, no wonder! Not what you'ld want
in a studio amp.

The input stage of the Caliber .50
also has this, but with different
values so it is not as bad, and I
am not sure about the .22+ though
I don't think they have changed that
entirely.

I am not saying this can't be a great
sounding amp but it is a sin engineering
wise and the high noise level of mine
drove me nuts.
