I don't get it. I use to run lots of switchers and 3-4 amps to solve these issues. I thought with the new bread of Stereo In & Stereo Out pedals these issues would be gone.... Nope. Guitar > fixed wah > Butah > 4 TB Looper > Loop 1 > memory man > i banes PT-9 Loop 2 > option 5 rotation (old box) > supra trem2 (Left) to AC30 TB (Right) to Deluxe Reverb or Marshall 18 watt Loop 3/4 (one switch scroll) > Scarab or DLS Deluxe Reverb Normal channel (sometimes split and Sent to AC 30 normal channel) Problem, if I use the supa trem2 last, it sounds wonderful but then the Option 5 sounds horrible. (Probably phase cancelation) If I use the Option 5 last then the Supa Trem is mono sounding. Options?
