OK, I've been checking out every clip from the early ones done by Slash to the early ones done by the southpaw player Marshall parades out to the ones by new owners who just got the amp. The amp rocks. I'm no Slash fan and can't stand G&R mainly due to the singer's voice. The amp is probably the best thing Marshall has done since the old 2203 master volume pre JCM800 amp. However, PLEASE cut some slack on the nighttrain song. I think I now know that riff simply because everybody and his brother who has played the amp seems to have an irisistable urge to play that song. The amp does soung so good, I'm selling my JCM800 2203x to buy one.
