Swart Amps Atomic Space Tone is one of their best selling amps, but it’s a bit too much amp for some people. The Space Tone Atomic Jr., however, is a smaller, lighter version of this powerful amp. It’s get plenty of soul and a lot of power, so even though it’s smaller, it’s not any less of an amp than the original ST-6V6se. The Jr. model contains the heart and soul of the ST-6V6se, but it also features a triode reverb stage that Swart spent over a year working on. This stage uses a dedicated 12DW7 tube that feeds the signal into a spring tank, creating some major reverb. In fact, you’d be surprised at just how loud and powerful the reverb from this small amp is.
The Atomic Jr. is a 5 watt Class A amp that uses one 6V6 tube for power. It has two preamp tubes: a 12AX7 and a 12DW. It uses an eight inch Weber Signature Ceramic speaker for the sound. A spring reverb tank in the bottom of the amp provides all the reverb you could ever want. The amp also features carbon comp resisters, a Switchcraft ¼ inch input and output, CTS potentiometers, and a solid pine cabinet. It retails for $1,199.
