I have owned this amp since 2009 and have used it on all types of gigs - I've powered a Mesa 8x10 cab in front of 2000 people and I've also used it with an Aguilar 1x12 in bar gigs. I always get compliments on the rich, modern tone.
The parametric EQ is where this unit shines. Start by setting the graphic EQ flat and play it for a few minutes to get used to the sound. Then play with the parametric mids and hear this head come to life. I really only needed the graphic to dial in the room at gigs.
If you like to have more grit in your tone, I recommend swapping out the installed 12AX7 for a Mesa or a JJ. Then you can use the Gain know to go from clean to spanky!
