Blender - signal mixer

A lovely little circuit to blend one signal with another. Your original signal goes to IN and OUT, and another signal connected to SND and RCV can be mixed in with the blend pot. A trimmer lets you set the volume level on the SND and RCV path (you could make it an external pot if you really wanted to).

Input caps included for both guitar and bass.

Why would I want to blend?

Bass player? Use a guitar fuzz but keep some bottom end by mixing dry signal with the effected signal. Experimatatorator? Build an effects loop pedal with signal level control.

Board-mounted pot for minimal wiring and easy enclosure mounting.

Please note: funny things can happen depending on the phase of the signals you're blending. If they're in-phase, you're ok. If they're out of phase you will get signal cancellation.

Kit includes: PCB, all components, hook-up wire, LED. If you want to build this as an effects looper with blend control you'll need to order jacks, footswitch and DC separately. See instruction document for details.
