Yeah, Ive tested a lot of different, amplifires, and I do agree that ENGL is the closest thing to a GP-1000, but there is sonething more magical about the mid-shift response that beats even ENGL. I haven't tested any modded marshalls fron 80-90, so I can't say anything about the other hair metal amps. But I've recently accuired a modded ADA MP-1 which sounds just like my Engl, but without that ENGL dryness which all of their amos have. And ENGL amps do got just as much bass response as a mesa boogie, I guess Alexi liked more chrunchy bass end these days.
