Hi,

I play the violin, and I have a dual pickup that consists of two mics outputting to a stereo jack, having the tip and ring outputting the two elements of the pickup respectively.

I was wondering if there is an effect that takes a stereo ¼" jack (or right & left using an insert cable), and has a mono output which is a blend of both channels, with a knob controlling the blend or dry/wet of both stereo sides.

If there is such a pedal, does it have an official name so I can use to search for various makes out there?

Any recommendations or alternatives?
