The effects on this are unparalleled. Usually on effects-based amps, the effect quality is second rate, but not here. I must say I am impressed. I never thought I would own a non-tube amp. Like most guitarists,I tend to be traditional and technologically conservative,ie vaccuum tubes good, transistors bad.
Tubes produce a much warmer, fuller tone than any solid state.
And they are touch-sensitive, which means that the harder you hit the strings, the more the amp overdrives, and a light touch results in a cleaner sound. Transistors simply cannot do this. You should confirm all information before relying on it.
