Check out "PEDALPCB" & 'FV-1', 'Octagon,' 'Pythagoras,' 'EEPROM' etc on youtube.
I'd recommend building an Octagon and use the EEPROM builder for effects you're interested in: Basically all the FV-1 PCBs are identical and you swap out EEPROM chips. I did so and as to be expected, some effects I use and some I don't, but the ones I use are amazing. 'Kaleidoscope' is a fav
thanks the_grumpy_gnome. I found pedalpcb.com shortly after I found Bugg FX daydream. The Kaleidoscope looks like it would be a really fun pedal. I'd love to be able to add a secondary footswitch to a fv-1 pedal for tap tempo, but from what I've read that is often done in the code.
I am excited about the the potential of an fv-1 and relay switching acting as a momentary switch!
