On channel 2 and 3 i use it.
Still need to get to know the amp though...
At 10 watts, Variac power, I can get Metallica's black album tone, Justice Tone, kill 'em all tone..... (i'm in a metallica cover band)
But once I play at band level (90watts, full power), I can't seem to nail it anymore.. very frustrating
I like it, but I changed to the preset knobfor channel 3 and had it turned all the way up and was digging the tone I had, especially in Mark IV Pentode mode. I thought for days I was playing with the graphic turned on but the graphic eq is much better for tweaking when you start to play louder I have found.
