@blowtorch. Who is writing those reviews? Real players or ... ? All I can say is I love mine. I run it with the Gain and volume 2 o’clock plus. Control from the guitar. knock down the attenuator/power scaling to quiet it down. Lively, dynamic and full. Very flexible once you learn how the controls work and interact. Maybe I got lucky. But I’ve run it for countless loud rehearsals for 2-3 hours in our hot little studio. And many shows. In fact I like it so much I’m considering the 20 combo for rehearsal (the 50 is so darn loud in a small room) and really small shows (maybe). Huge value for the price. Curious why you and @Jakedog are looking at tubes again though.
