Well, starting off, I really liked the lower gain tones I was getting out to of the Nitro. That's not why I bought this amp though. The clean channel seems alright, but, for all I care, it may as well be a one-channel amp. After spending about an hour and a half with it on Friday night, I could not find a high gain tone I was completely satisfied with. I know this is supposed to be a darker amp, but to me it is brighter than a lot of amps I've owned. I was thinking maybe it was the KT77s that were giving me concerns - this is the first time I've played these tubes. In order to get a nice thick tone like I liked, I had to turn the resonance knob way up and that caused the low-end to be boomy and the palm mutes were not tight. I also couldn't seem to dial out a certain high-end frequency that was just grating on my nerves. After Friday night I was dejected and seriously remorseful that I sold my Engl SE to buy this amp. I was already plotting ways to trade away this amp without taking a huge $ hit.
I sent a few PMs to the Windsen (shredhead34) the resident Nitro expert. He was kind enough to help me out with some things. I figured I'd try the el34s and sell it if that didn't do it for me.
On Saturday, I figured I'd go buy another MXR 10-band eq to see if that would help. I put that in the loop and that cured all the issues I was having. I get a nice thick tone without the boomy low-end and that piercing high-end frequency that was giving me issues was easily fixed.
So in the end, I'm pretty satisfied. The distortion is saturated yet clear. I think the saturation level lands somewhere between a VHT and ENGL. I think it's reminiscent of my old D60 with more saturation. People compare it to an uberschall but I don't think it is as saturated or has the low end of the uber - though it certainly has a lot of low end. It's definitely tighter and the clean channel is balanced better. You turn the gain up to eleven and it doesn't get muddy or fizzy. This amp is much more open sounding that I'm used to. My Diezel can be fairly compressed. Turning the resonance knob up definitely compresses/thickens the signal. The Diezel has kind of a hi-fi voicing to it so the Splawn voicing is a nice alternative. I don't think I'll ever like anything better than the Herbert's channel 2+ though.
Lastly, I don't know what the difference between od1 and od2 is supposed to be. I guess it is one more gain stage. I didn't think there was a dramatic difference in sound - just more in the feel I guess. Kind of like effect of a very slight clean boost.
Speaking of boosts, I boosted the amp with an OD808 and the Xotic BB preamp. I guess I just like the transparency of the BB because I always prefer that. I don't know why I keep the OD808 around. The boost does what the boost does.
I just ordered a Weber Bias Rite so I'll be putting trying the el34s in it soon.
