I picked up two of the little Epiphones when they first came out ("$99 for a real tube amp -- are you kidding me?"). One remained stock to this day, the other got the full-bore Mercury Magnetics mod, complete with a socket for a 6V6 tube, so that you could use the EL84 or 6V6 separately or in tandem. There were a lot of other mods available for these little suckers, and I have a few bags of them sitting around that I never installed.I guess it was around that time (15 years ago) when Blackheart and Epiphone tube amps were very popular. A lot of people modified them.
I have a Laney VC15 which is a great 15w tube amp too.
By the time you got done installing the MM mod, the little bugger was fast approaching a $500 bill and that just stunned me. But it's a pretty compelling little amp and dead reliable to this day.
Most of my amps are 50W or above, but I have a pair of Atomic Reactors that are 18W (two EL84 tubes) power amps, housed in an oversize cabinet with a single 12" speaker and a space for one of the desktop modelers (Pod bean, M-Audio black box, etc.). Chinese manufacture and the tolex is poorly applied, but overall pretty solid. At some point, I'll probably pull the tolex and Duratex the cabinets. Thanks to the design, I can actually take a stereo send from the modeler and put one amp on either side of the stage for a wider distribution of sound (and stereo FX, if appropriate).
