Brambles

Myles, I really appreciate you spending so much time sharing your expertise. I was wondering if you know of a pedal I have in mind: I want to take two inputs of same signal level and blend them into one output of the same signal level. Kind of like a pan pedal, only in reverse. I tried the Ernie Ball volume/pan pedal but it only wanted to pan between the two outputs. Do you know of such a pedal, or will I need to design one with an electronics wiz? Thanks again -
