I bought this amp to compare to a Friedman Dirty Shirley mini in hopes that I could return one or the other. I kept both. The Shirley is fantastic. That being said, this amp is instant 80s Marshall tone. It can cop Appetite for Destruction easily. It covers Lynch and Rhoads tones too. It can even do cleans and Plexi grind. It's simply the pinnacle for Marshall tone. If you're contemplating this or a more expensive amp, choose this. 20 watts is plenty for any situation.
