Re: best cheaper stack?
Those Ibanez ToneBlaster amps got good reviews, but I've never played one. That, Crate, and the B-52 might be the way to go if buying new.
Used, and REALLY cheap? I would look at Music Man heads, either the 65- or 130-watt versions. Matching 412s are hard to find, but these are really great amps. They are a hybrid-design, with SS front-ends and tube power.
My other favorite here would be darn near anything from Peavey! Mace, Deuce, Butcher, VTM, Ultra, XXX, XXL, Triumph, Road Master, Rock Master, 5150--there are a lot of really good sounding amps here, that can be had for a song. Peaveys are great value, very reliable.
Another amp that you can find dirt cheap these days that can really rock are the the old SUNN amps. The tube models are getting collectible (translate as expensive), but the Concert, Coliseum, and Beta Lead heads will still pin your ears back. SUNN had some of the best speaker cabs in the biz, too. The old V-baffle 612 or 610 cabs project unbelievably well--way better than a standard 412 cab.
These amps won't have a lot of the bells and whistles of modern-day amps; but if you are looking for amps with a lot of clean power for use with a pedal board or processor, you may find something here that will sound great--not only to your ears, but to your pocketbook, too.
Good Luck!
