peter	Re: bias/rectifier observations/questions It is a semi-buffered loop(!). Reasoning being as follows: after the tone stack, there is lots of signal (50 V p-p), so I can divide that down say 1 Megohm to 20kohm, getting a volt or so at a sufficiently low impedance to drive pedals etc. On the return there is a gain stage because I need a few volts at the PI input to drive the power amp to full power, probably more than a pedal can put out. Feel free to criticize this scheme, because it is half-built, so i can still make design changes! Thanks for your input.
