New Idea

[Travis]

Hi everyone!

I world like to build some Octave pedal with the option of use a expresion pedal to engage more or less Octave effect. Some ideas if it's possible?

Maybe with the bit Commander build and using a custom expresión pedal to move the Octave effect

If you start with something like the Fuzzy Fox, that has a switchable octave, maybe you can replace the switch with a pot to mix in the octave effect rather than turn it on/off.

There are many resources out there documenting how to insert a TRS jack in between the board and any potentiometer (the electric Druid filter fx build doc comes to mind). So boards like the parenthesis or any with a blend function could be converted.

You could also wire up a stomper to select between two pots; one of the pots being from the expression pedal — then you'd have a pre-set as well as go psychoschematicinsane!

Or if you just need two settings, just the switch and two regular pots or set the second pot as a trimmer that's preset...

Could be nice! But I dont know How to do It

This is of course not for a switch, but good general instruction. All credit to electric Druid for the info. I think replacing a switch would require including a blend circuit and not just an expression jack/pedal.
