OK so I'm pretty happy with my pedals and cables but it's time to get down to the real nitty-gritty... I want: 1. a loop for my entire pedal chain so that A. my straight-to-amp tone is as clean as possible B. I can switch on/off a group of effects with one stomp 2. a loop for my tuner so it's not in my signal chain at all 3. a parallel mixer for my delay pedal 4. an a/b both switch to go to two amps. I'd prefer to have one switch dedicated to each amp instead of having "both" and "or" switches. Ideally this entire thing would be one box, yes I know it's a tall order... so I'll probably end up with at least two boxes. I'm thinking that there will need to be buffering for the parallel mixer and a/b functions? Recommendations/suggestions welcome!
