    Hello,

    I have a MINI ME Chorus PCB 2020 and I want to add a mix knob. I want to be able to go from 0% to 100% wet. How can I do that ? I was thinking of replacing R12/R13 with a 50k pot (schematic), can it work ?

    Maybe try clipping a pot across the operative points. If you use croc clips, then you don’t have to commit to the PCB until you’ve tested it out. From the look of the schematic, it should work but you might need a nominal value to prevent the pot from cutting out at either end, say 1k or so.

    Hold on a second though, isn’t that what P1 is supposed to do in the first place?

    The kit is not assembled yet, but I might try that. P1 is the depth of the modulated part of the signal, I want to be able to have a high depth but a low mix so a lot of clean signal

    I would use a Buff N Blend.

    Hi Barry,

    I would like to know, how the Buff N Blend could work wirth the Mini-Me, since it is a phase inverting schematic?

    There is also the point in the question of the thread starter, if it’s possible to get 100% wet with this schematic. A lot of pedals get only a 50/50 ratio of dry/wet. Could you answer this for us? Thank you!

    You can get it to work with the Mini-Me by adding a Stage 3 Booster for example in series to correct the phase but if you want a true mixing function, phase correction, and 100% Wet you need the Paramix.
