I thought I'd try reducing the bias on my SRZ to see what effect it had on output and tone. I dropped it down to 28-ish on my Bias Rite. It became immediately apparent that any change in output was not worth the complete loss of tone. The amp was sterile, lifeless, and had an irritating brightness. I raised it back up to 34+ and it sounds fantastic.
I don't know if too many guys are going to try this as a means of reducing output, but in case someone else comes up with the same idea, I'll save you some time. It completely killed the tone of the amp. My suggestion is to use an AirBrake or play in a bigger room!

yes the master volume works well for me , when volume is an issue I roll the gain way back and push the amp with a timmy or bb or both. sounds huge I just got new tubes for my SRZ gonna be installing today , I run mine on the HOT SIDE right about 40 ma the 77's handle everybit of it the brown sound with ease!!!

I've toyed (even recently) with the idea of an SRZ. I thought the MV on the SRZ was supposed to be great to allow low volume playing (well, not MV but volume and gain controls)?

The MV works as well as any MV I've seen, but for some of our smaller gigs I have to set the MV between 9:00 - 11:00 and Gain at 9:00. I was trying to find a way to get those dials more in the middle of the sweep. Cold biasing is not the answer!
I was practicing in my office this morning and I had both set around 9:30. Plenty loud enough for this small room, and probably loud enough for some 100 seat bars. That said, a 60 watt amp is not really designed for a 100 seat bar or a 10x12 office! The AirBrake is a big help, though.

This is where I think it'd be helpful to be more in the middle of the dial, or maybe have a pot that doesn't have as wide a range (if that makes sense). This setting is fine in my office: This setting would probably be plenty loud enough for a small bar gig. Just guessing, of course. Hard to tell in a small room. Not much physical difference between the two settings, but a noticeable volume difference. (Killer OD tone, by the way! Had to break into a little Detroit Rock City!) I think the Gain control adds more volume faster at the low end of the dial, but I haven't experimented with it enough to see where the real sensitivities fall. I typically set the gain I want and dial up my volume. Hope that helps. *** Edited to add - I just spent a little more time with the SRZ and it seems like the gain knob does add more volume at the low end and almost none in the top half of the dial. I never set it that high as I need to be able to clean it up fairly easily. Really sounds great up there, though. If I was running a 2-head rig, that gain knob would never be below noon!

Thanks Ches...this is exactly what I was wondering!
The SRZ may be my '80s rock ticket !

Jamie - It has the tone I want, but an over-abundance of horsepower. If the Doc had a way to mod this to lower the output by 50%, I'd probably be all over it.

I understand it can be very loud. I have learned over the years how to use it i. Almost every situation. I can get bone crushing overdriven tones to nice searing blues Bite it has it all . I thougjt about addimg power scalimg to mine but. For now it works great with the master volume. Good luck in the sale. Someone will be all )))
