I recently decided to join a cover band just to put my JTV/POD HD500 to work and I'm extremely happy with it in that format. We're playing a lot of different (mostly down) tunings and the flexibility of this rig is incomparable. Everyone who's heard it is impressed. So much so that the other guitarist ended up getting a similar rig. People have been raving about how the guitars sound. Did I mention setup and tear-down are a few minutes, done. The acoustic tones are a super big surprise to those watching.
Earlier this year I decided to bring all my guitars back into standard tuning and use the JTV for everything tuned differently. Not only have my guitars come back to life - in the sense that I believe they're made to resonate at standard tuning - the L6 rig has really become a great learning tool for different tunings. I initially bought it for another cover band, which immediate after getting going disbanded and the rig actually sat here for quite some time. ...ah...I'm rambling...
