I actually ended up running the amp while it was backwards on my cab and saw the V3 preamp tubes was glowing blue. Turned it off and replaced it with a new one and there it was, exactly what I was hoping it'd sound like. I recently had a temporary moment of insanity after letting GAS get the better of me and listed it for sale, but I plugged it in yesterday again and was reminded by how great the amp sounds.
The clean channel is AMAZING. Seriously, can't say enough good things about it, it's absolutely killer, especially when cranked for some sick Plexi tones. Boosted, it easily gets into hot rodded Marshall territory.
The Crunch is where I stay most of the time. It gets brutal with tons of clarity, but reacts to picking dynamics really well, so you can set gain lower than usual for chords and then dig in when you need more. This channel sounds like what I remember the Deliverance being, though it seems to be less gainy still, or maybe the taper on the pots are more linear on the D60 I had. I remember playing at close to noon on both gains but I'm about noon on 1 and 2:30 on 2. I run this on 100w.
The Lead is where this amp differs from most other VHT/Fryettes I've played. It can get really saturated like most of the high gain amps people know and love, but retains more clarity than most of the other options out there. It can also get very smooth for leads, which is nice. I run this on 40w.
I've been running the amp with my PS-1 the last few days. It's easier to control the volume this way, but I wouldn't say it's needed if you can get to decent levels (which is honestly where it's going to shine, regardless, since no amp is going to sound that great if it's not at least moving a decent amount of air). Maybe for the clean channel if you really want to push it.
Really, the only thing I wish this amp had was a shared master volume. Matching the Crunch/Lead levels isn't too bad, but the Clean can get a bit tricky. Not a huge deal, but I could see how it might be a bit annoying live.
