Not a heavy enough sound for me, that's why I'm going to sell mine. This unit also does not have enough gain for me. Sounds like a Dual recto, but imagine if you could only turn your gain up to 5. It just starts to get downright nasty with the gain all the way up. Does not sound very wet and elastic.
Cleans are dynamic and it still does sound very good for rockin and has a great, rude tone.
I couldn't keep away from it when I first got it. I think this thing would suit very well rock and modern rock sounds, modern blues sounds ok. But if you're really playing blues, you should be playing an old fender or marshall. I think this preamp would be great in a studio tracking situation. It certainly has a lot more usable sounds than my Studio Preamp, it just doesn't get as heavy.
