MultiBand-Distortion

Inspired by VFE Triumvirate I built this multi-band Distortion Pedal:

Very nice. Where does a brother get those trim pots?

You can buy these potentiometers from the usual suppliers (Mouser, Farnell, Digi-Key).

That’s really cool. Do you dig the sound? Lots of trimmers! Do you know what you have the bands tuned to, or is it just whatever sounded good?

Do you know the manufacturer or series?

Edit: Never mind. Vishay CT6.

Edit: At DigiKey, anyway. I'm not turning up much at Mouser or Newark.

Those are indeed some very nice trimmers. Nice build too!

They look like Lego

Way cool! Do you find you don't need any tone control on top of the pedal? Or you find yourself thinking of one or 3 tone controls on top?
Also, the outputs of the gain stages are just tied together. Some circuit designs use a summing op-amp to add the signals together.
Anyone know why one would use a summing op-amp instead of just tying them together like in this circuit?
