Swart Amplifier Space Tone Atomic Jr. Head - Tweed

Swart's 5w options have been creating a storm since introduction way back in 2003 with the ST-6V6se and later the Atomic Jr with reverb. Now you can get these same circuits in a cool, tidy, grab and go head cabinet.  The Reverb is the same great circuit seen in the Atomic Jr. with 12DW7 fed into a spring tank for near surf-esque reverb. The circuit remains über simple for the best touch sensitivity, tone, and responsiveness.  The Atomic Jr include Tube rectification with the GZ-34.  There is a switchable EQ response in the Atomic Jr Head. Aside from the ST-Stereo, this is the first single implementation of ANY of our 5w amps into a dedicated head cabinet.  Honestly, we REALLY love the little 8" cabinet/speaker combination but for those that really desire a head, this would be for you.
