minimal blender

[neurino]

I'd like to build a selectable series / parallel looper with volume control.

Since I want to fit everything in a 1590A enclosure I'd like to use this FET minimal blender from here



but I need to change the 50K pot with a 500K one

Does other values in the schematics, needs to be modded to best fit the 500K blend pot?

Also is really C2 overkill like notes say? Space left is about to be a few...
