Not to be too dramatic but my search is over. This amp produces the tones I loved years ago . . .when I was falling in love with the guitar (Gary Moores heavy rock stuff . . . .Richie Blackmore . . . . Schenker . . . . . Michael Lee Firkins . . etc) . . . .and that's really just part of what the amp will do. I claim very little experience with Marshall amps as I've mostly owned booteek Fendery or Voxish amps. . . . .but this sounds like a killer Marshall to me. I feel sorry for our other guitarist (who just got a new Orange amp) this sunday . . . . .he will be dominated . . . in a loving sort of way. The feedback knob really works great for softening up the tones or making them cut . . . . I like them a bit softer but the option is great to have. More gain than anyone playing live could possibly need IMO . . . . adding a touch of the Plimsoul up front to channel 2 (with gain at half) compresses the feel and you get pretty liquidy . . . .adding channel 3 will do this too but there are some differences. The clean channel . . . . .this was so important to me . . . .and I feel that the PT100 really delievers gorgeous Fendery tones . . . . .I do not feel they lack depth . . . .just wonderful. I have not tried the loop but I intend on getting a nice ambient delay for a little slapback. I'm running the head through a MojoTone OS 1x12 semi openback cab with a Scumback H75 and it sounds great . . . .a buddy tells me I need to try a EV12-Classic . . .so I'll hunt one of those down for another cab. I've had so many booteek amps and have been on the gear merry -go-round for years now . . . . .I want to get off and this amp is going to help me do just that. I'll post a more indepth review after a week so I can gig it. Special thanks to Greg and Danny at Rocket Music for taking care of me.
