Swart Amps
Swart amps was created by Michael Swart, a musician and recording engineer based out of Wilmington, North Carolina. Swart owned a 24 track recording studio in Wilmington, and he only used vintage tube amps for recordings. 
However, while he often used Ampeg, Fender, and Vintage Vox amps for both his recordings and his live performances, he always felt like something was missing from these vintage amps. They just didn’t give him the sound or tone that he wanted.
Because of this, Swart set out to create an amp that would feature all the distortion and tone that he wanted for recording in his studio while still maintaining the flexibility he needed. The custom tube amps he started working on eventually lead him to creating the Space Tone, the first of Swart’s amps. It worked perfectly for small studios, small venues, and for playing at home. It gave off the large tone he wanted and provided the distortion necessary. He followed this up with the Atomic Space Tone, and Swart Amps was born. (more...)
This gives the amp’s circuit very little insertion loss. Just like all the other Swart amps, the Atomic Space Tone Demo features a ST-R that is tube rectified so that the AC filtering is excellent and has a very nice tone and compression. This means the amp won’t have that harshness that many others do.
