    So you only have two pots on your old scrap iron amp that you are rebuilding. How do YOU wish to use them in a guitar amp? Please vote in poll and explain your reasoning in response, if this interests you (as it does me, obviously!).

    Thank you.

    If there's NFB, I'd have volume and presence. If not, volume and cut.

    Oops, I want volume and presence too. I can get tone shaping from a Tim or other stomp box (even a wah).

    Me, I'd go with volume and tone. Wire the tone control so it boosts bass at the low end and boosts treble at the top. There are circuits available that show this.

    Screw that master volume ****, just turn it up and get the power tubes working.

    If the amp is voiced correctly so that it doesn't woof and fart when you crank it, a passive tone pot that shaves just a little off the top to compensate for different guitars is the thing to do.

    Volume and Presence assuming you have an effects loop. Then you can just EQ in the loop.

    Push pull pot that does volume and switches Neg feedback on/off, and a concentric pot that does tone and presence (when neg feedback is present).

    I'd go with what the Carmen Ghia does. Is that a passive tone control?

    Very interesting. Please feel free to toss in more ideas or elaborate. If one wanted to voice amp around particular type of guitar, say strat, that might open up options?

    Thank you for participating.

    donny, do you have a link or two? I remember seeing some circuits like this in the past but when I went to look for one recently I couldn't remember where I'd seen nor could I find one.

    How would you implement mid cut/boost? Like Big Muff in Duncan's TSC (though that one passive)?

    Thank you.
