VHT Special 6 Ultra Head by blurred8218
There is a half power switch that brings the wattage down to 3, and then an attenuator that further lowers it down to 1/2 watt. All tube, this thing offers an effects loop, secondary gain channel, and footpedal-switching. It's all hand-wired, portable, takes pedals well, and easy to mod. It sounds full out of a 4x12, and stands up well during band practice and recording sessions, and records beautifully.
With so many options to choose from among low-wattage amps, the VHT Super 6 Ultra offers a distinct gain voice, and a very agreeable pricetag. Also available as a combo.
