I have found that on humbucker guitars, since I have never played around with volume and tone pots while playing, that I always end up clipping them out of the circuit. On the only guitar I have that has both a single and a bucker, sure enough the bucker goes straight from p/u to output (well, it's grounded). I find that they live very comfortably with my Tele and ASAT Classic after doing this, and I can switch back and forth with no adjustment to the amp...I just make sure the tone is rolled down a hair on the single-coil guitars. Of course, pickup selection makes this work as well... Oh yeah, and most importantly I love the sound of buckers after clipping the controls out. My Heritage H535 with it's '59s straight to output is a joy to behold. So, anyone else do this?
