Thanks everyone! Your info will help me get a better and faster start.
I probably should have said this earlier, I know very little about amps. I'm currently using a Boss GT-100 multi-effects...and I found it best to not use its amp models. Instead, my tone is totally controlled with effects. I considered doing it this way with my Helix, which will arrive this Friday, but since the Helix amps are good I might as well take advantage.
I played acoustic guitars (mostly classical) off and on for forty years and switched to electric about five years ago. My hands are good but my repertoire is modest. My GT-100 taught me a lot about pedal effects but not much about what different amps are good for or how they sound.
