I have a 70"s Mu-tron III in my FX chain that sucks volume from the signal just being in line with or without being engaged. I just picked up a Loooper in a trade that provides 2 true-bypass loops. This has been great for determining my problem pedals. The Mu-Tron is the only pedal that I have this trouble with(the Mu-Tron Octave Divider and Q-Tron are fine). I have since put the Mu-Tron III in Loop 1...It's great to have the effect without coloring my tone when it's not engaged. My problem is that there is a volume drop when adding this loop to my signal. I would like to boost the signal coming out of the Mu-Tron III to unity without (gasp) sacrificing ANY Low End. Any thoughts?
