Swart Space Tone Atomic Jr. Two-Tone

Swart · amplifier

The Swart Space Tone Atomic Jr is a 5-watt 1x8 combo, the smallest amplifier in the range, and it introduced a patented triode Space reverb that owners regularly describe as among the most musical in-amp reverbs ever produced. That reverb is the model's reason for existing rather than a feature added to a small practice amp. At 5 watts through an eight-inch speaker it saturates at genuinely low volume, making it a recording amplifier first. This Two-Tone version refers to its covering. It suits studio players who want lush valve reverb and early breakup at low level.
