adding momentary feedback looper switch to looper pedal

[adamjuresko]

heya,
I plan on making this mammoth electronics 5 channel looper in the near future and i absolutely would love to add a feedback looper with a momentary switch between the last loop and the output. how exactly would i do this? including the diagram if anyone would be kind enough to point me in the right direction! this will be the first thing i'm building and i'm really excited to start working on it


thank you!
