Hello,
I have a PS-100 that I enjoy very much using with a Friedman JRX.
While I have a breakout box for between an amp and speaker cab I can use that gives a signal, I started wondering if you could use the PS-100 as a slave amp by connecting an amp’s efx loop through the efx loop on the PS-100 itself?
My first thought is ‘no’ although I can’t explain why, other than it might create some type of ground loop or interference of some kind.
