Ok.....so here's my initial reactions.
The blue marvel that comes stock just doesn't do anything for this amph, even with dialing it up and letting the speaker break up.....its just ehhhhh.....
I put in the Celestion G12M in it and it sounds better.....but the speaker is NIB so it needs some break in. My initial thoughts (it was 10:45 at night when I got it back....so I power sponged the crap out of it) is the amp has serious potential as a good gigging standard. The sponge is nice, for playing around the house, but I really want to let it rip tomorrow so I can see how she sings with the speaker reacting to the tone controls as well. Right now IMHO it really wouldn't have mattered if I took the speaker out of it and played it at bedroom levels....the dynamics and overall sound were better with the greenback, BUT I'd put money on it that the amp will be reviewed tomorrow AFTER I get to crank her and blast it. The Verb isn't so hot on this amp, but as long as you just want a little of it, and yer not surfin' you'll be golden. It has a Blues breaker on steroids kind of sound in the low gain, and the high gain IMO is very JCM 800.....I really want to crank this amp and run it through a bunch of cabs......just to see how awesome it really is..... for now I'm holding my breath cause I get to take it out to a Jam on Saturday!
