I have an archtopw/a minnie Hbucker and soundboard transducer. I want be able to blend them . I need to match the impedance/volume so the volume is the same throughout the throw of the pot . Will Waldos UGB work for this application? I dont want to make any wholes in the guitar. I tried to build a box from Radio shack with a pre amp and blender but i just wasnt able to match up the volume 
. I think there were to many pots & ground loops going inthe circut .Any ideas would be appreciated
