Like new (June 2021 build date) – Swart Space Tone Atomic Jr is a soulful little amp from the hands of Michael Swart. A fantastic little beast of an amp (only 14 pounds). Perfect for home use, band rehearsal and recording. At 5watts (class A) it can get a lot louder than you think, with a lovely natural breakup and gorgeous on-board reverb (spring tank). Like all Swart Amps, the Atomic Jr. is all hand-wired, point to point, and cathode biased with no internal adjustments necessary when changing tubes out. Very little use on this grab-and-go gem! Comes with Tuki padded amp cover at no additional cost. Will ship with the (new production) tubes that it came with - or I am happy to leave the NOS tubes that I installed (as pictured) at a slight additional cost (happy to discuss)...
