I'm liking it so far. Channel 1 is brilliant. Channel 2 could use another 1-2 notches of gain. Thus far, I'm not finding anything useful on channel 3 after about 1:30. It get noisier, but not any better. I'm finding I sit at one notch before 12:00 on the gain with my main RRR with the Norton, and one notch after 12:00 with the EMGs.
The mid knob is the key on all of the channels. Huge changes can be dialed in with that mid knob.
*Edit - I should note that mine has been modded by "Kruse Kontrol" with their Super Sonic Mod. Not exactly sure what it does, but it's adjustable with a pot on the back, and it seems to dial out mid level mud. Not that the amp is muddy, but that's the best description I can give.
I have a feeling we have VERY similar tone taste. I also wish 2 had a tad more gain and a little before 12 is prime on 3. But, the mids of 2 are a lot more dynamic than 3, which is a tad more scooped despite my mids always being cranked. The gain issue on 2 is fixable with a pedal, though. Great amp, though. Since mine has been out of commission I've been using a dual rec and while I finally got a decent sound out of it, it lacks sorely in mids and the gain character is crap compared to the EVH. Not nearly as crisp and tight.
