Parallel effect loop / aux circuit.

[rosscocean]

Hello all

I'd like to have a single parallel effects loop pedal, like a aux send and return on a mixing desk.

I've read a few different pages but I think some might be more complicated than I need and I'm not very clued up on opamps, I've only really built transistor based stuff on vero.

If you know of a simple circuit with a vero layout that'd be brill.

Many thanks

Ross
