Thanks Trout.

Looks like i'll try a Fender Pro then. Some simple questions (wouldn't be any fun with out them ).

Can i drop one of the 12ay7 stages? I only need a single input.

Can i add a "master" volume control after the preamp stages so i can have the distortion, but without killing my ears? I play in a small room most of the time. If i understand this right, i would replace the 56k resistor before the 6l6's with a 1M pot, with coupling caps on the legs so no dc gets to the pot, correct? I'm looking at this 5e3 schematic. http://www.ampwares.com/ffg/schem/pro_5e5_schem.gif

I would connect the pot exactly like it is connected in the Spitfire schematic, correct? http://www.diyguitarist.com/Schemati...eSchematic.bmp

Thanks for the help.

Dropping 1 12AY7 would be pretty simple, I have added a master volume to a very similar circuit and it works great!
In Fact, it had little or no effect on the overal tone quality to my ears.

Take a look at the Master Volume in this drawing.
Simple parts needed, (2) ,022/600V caps, (1) 1meg pot.

I found that you can get some great overdriven tones cranking the pre-amp volume and not get the ear bleeds. It is a different type of distortion though. More of a traditional pedal sound and no output tube growl of a fully cranked amp at low volumes.

I would not use that paulC mod on that page though, it sounds nice, but it appears to be pretty hard on the output tubes.
