The combination of sound and features is just mind boggling!!!! I use this in combination with a small but powerfull MIDI pedal and the Line 6 HX One. With the built in midi controllable reverb and delay, and one effect from the L6 either in front (drive, comp, fuzz, pitch) or in the loop (mostly different mod effects) of the amp I can dial in every possible sound I would have need for (I also have a vol/wah/exp. pedal). Awesome sound and super portable setup. Finally truly amazing tube amp tone and total flexibility without the option paralysis of amp sims (I had a lot of them).
