I use the Go 95% of the time I play guitar now. I don't need more processing or blocks, as I do simple setups like OD > amp > IR > delay/reverb. If I wanted something more complex, I'd buy a different unit, but I dont need anything more complex.
I want more amps:
5153 50w blue channel
Friedman Dirty Shirley
Cameron Atomica
Sunn Model T
Give me more world class tones, and keep things simple.
A total revamp of the stock cabs across all the platforms would be nice, but IRs kinda solve that problem anyways.
Power amp options - the ability to switch power tube type, or mixing power amps from different models? OR a generic 6L6/EL34 power amp sim.
