I've had mine a few weeks now, used it for a couple of rehearsals and a gig and I just love it. Works great through an amp or direct to PA. I like to keep the Sans Amp section pretty clean (drive about 12:00 with low output pickups) and just a bit of reverb. Then I set the delay for slap, sometimes I'll tap tempo depending on what the song needs. I don't use the Plexi much but I copped a pretty good Santana tone this afternoon with the tone set about a third up and the drive dimed on the neck pick-up of my Albert Lee MM90. Anyway I play a lot of jazz, blues and 50s rock/rockabilly -- all mostly clean. But I like a hint of breakup and that can be hard to achieve with a tube amp without turning up louder than is practical for me. The Fly Rig gets me there every time, no sweat. It sounds fine through my Bose L1 Compact, but even better with my BF Fender Vibrolux. So I hope to hear how other people are using theirs and how they like it. Is it an integral part of your sound or just a backup to your pedal board? Be cool to hear about the new RK model too. Haven't seen a lot of info about those yet.
