Man, there's a lot of stuff out there. The Orange rocker 30 is like 1400.00, Dr Z, I'm a big fan of Zinky/Supro, If he likes the Marshall thing there's the JVM, the 1987XL, the "new" JTM 45.
Then there's stuff like Rivera, Genz Benz, (El Diablo or Black Pearl) the Peavey JSX, Oh yeah, THD and the Krank Chadwick. That's a good start right there off the top of the noggin. That function of Musician's Friend where you can search by price is nice if you want one of the big guys. But with that kind of dough he could get something "corksniffy". If he's really got that kind of cash to drop on an amp I'm betting his biggest problem will be narrowing down choices. Man, that's a good problem to have!!!
Just slightly over your budget new, but definitely check out the Roccaforte Custom 30 or HG30. www.roccaforteamps.com
The 30 watters come stock loaded with 4 6V6's in the power section, but have the capability to also run 2 EL34's without a rebias to yeild 50 watts.
Even with the stock 6V6's you'd swear you were listening to EL34's. Great Master Volume as well.
Lot's of clips on the Roccaforte site. GREAT Marshall voiced amps!
As much as my friend would like to think he is, he's not a refined player nor does he take any time in trying out gear. So it's always been pretty much what I suggest or what he sees his friends playing...
He'll probably want to have something in the Marshall vein, so I'll have him look at the Roccaforte or the Reeves.
You might get with teleman here on the forum. He builds a killer PTP amp at a great price that's in the ballpark of the type of amp you're looking for. Mike doesn't call an amp complete unless he's 110% satisfied with it. I have two of his amps and love to hang out at his place talking mods.
