Hello there,
thank you for your quick answer (sorry for beeing so slow, i had .. actual live concerts !)
I come in and go out in Mono, this is with 1 jack in, AND 1 jack out.
But it always has been like since 5 years, and suddenly know I loose the A-channel (on some preset only: Only the Octaver and Synthonizer are working properly).
I do not use any special routing, as my pedal is set on ‘normal’ (see attachent).
