I stumbled upon a very cool tip while researching some guitarist/gear/gearpage stuff.
Scott Henderson (think modern jazz) uses his Boss RC-2 looper in his rig to record his rhythm and a lead part. Then he walks through the venue- at all angles- to HEAR what the audience hears. From there he decides what reverb, if any, to use and what his tone adjustments should be as well as his delay settings.
I wonder what I would hear if I walked around and listened to what I play. (kinda humbling, eh?)
Its a good practice! Hmm…. I think some of us “tone crazies” should take a peak into this!
