Agreed.
High Gain, very tight and clear sounding.
Gain wise, there's plenty of it but it's not as compressed, not as saturated or greasy. Thus where alot of people say it's not forgiving. My opinion though, you get used to it the more you play them. I do hear more of a cross of Hiwatt meets Marshall. Big tones, not as naturally mid range as a Marshall, lots of low end bloom but again, you can dial them in tight.
Dialing them in is always a balance of Presence and Treble IMO alot more tonal interaction between those two as say versus a Marshall. And dynamic, the harder you hit the more you get. Cleans up well on how gain tones as well.
I owned the Pitbull years ago and own the SigX now. Granted my ears favor Marshall and the Sig is a little more that realm IMO.
Overall great amps that have their own thing going for them.
