Thanks Nick

I understand what you say.

The purpose is, to route two different instruments to a looper – alternating use of course.

SM58 has low output level, yes, although it is not inaudible. But I’d need a preamp indeed.

“single mono or single stereo instrument” – I stumbled over that. Thinking of a two channel device on a hot sunday afternoon … and yes, I’ll have to rethink.
