Using Pedals with Op1

Hello!

Dumb question but do I need an interface/mixer to use guitar pedals with the op1?

Guitar pedals, and synths etc, use different signal levels.

In effect, synths send and receive/expect hotter signals than guitars and guitar pedals.

Ideally you should use something like Eventide’s MixingLink to match it all up. But in practice, just turn down the OP-1’s output when you send it to the pedals, and see how it turns out.
