Signal path would similar to a Fender Twin ie Gain Stage>Tonestack+Volume>Gain Stage>PI>outputput stage.  However, the tone knob changes things quite a bit. With the tonestack at minimum, the amp is where a Fender Twin/Blackface would be with it's tonestack controls at about 1 o'clock.  As you bring up the tone control, the tonestack gets progressively more bypassed, bringing the gain up and slowly eliminating the scooped mids.  This is very useful for a PEDAL PLATFORM. 
This is a lifetime amp, and is loud enough and soft enough for almost application. 
2 x 6L6, 2 x 12AX7.  Presence and depth offer some more flexibility (Depth does to the low end what presence does to the high end)
8 and 16 ohm speaker connections. 
I doubt ANYONE has built more guitar amps than I have.  Nor has anyone built the VARIETY I have.
