Using 3 amps; SLO100 as core dry, Mesa stereo/fractal as wet, and an EVH 50iii as the lead over the top. My EHX ABY had a ground loop. It was on the EVH when engaged or silent. So I purchased the Lehle SGOS and the Lehle P split iii to isolate all amps. Dammit man-ZERO noise. I am so enamored with what I got. I know there is better stuff out there. I know this is a but ton of money and maybe I’m not good enough to own it but who cares. I’m happy. Can’t wait for my next show. Yes lots of shit to haul but since my son owns a trailer company I get to back this right up to the stage and let the young folks put it out.
