Quick update: So it is week #4 and I can't stop playing this amp.
I don't know why I didn't bought it much earlier.
I'm still stuck on red channel and so far has no intention to move to others
The amp is very fun to dial and it reacts to knobs way differently than some others, primarily comparing to EVH 5153. Very interesting to discover how gain + presence + highs together are affecting the sound. Like add more gain and it adds more bass too.
So far I'm very happy.
Another observation is this crazy amp is a perfect match for guitars with emg. I'm now feeling a scratch to outfit all my guitars with 81+85. It is an instant killer tone as on many metal records I love. I can't believe it sounds so tight and full and literally a wall of guitar sound without mud whatsoever.
