Swart STR-Tremolo Combo

The Swart Atomic Space Tone 1x12 Black combines vintage-inspired tube tone, exceptional craftsmanship, and expressive onboard effects in a compact boutique combo amplifier. Delivering 5 watts of single-ended Class A power, the Atomic Space Tone features a point-to-point hand-wired circuit with zero negative feedback, offering exceptional touch sensitivity, rich harmonic complexity, and natural tube breakup. Powered by a JJ 6V6S output tube and GZ34 tube rectifier, this amplifier produces warm, articulate cleans that transition smoothly into thick, harmonically rich overdrive as the volume increases. Swart's signature tube-driven spring reverb adds lush, dimensional ambience, while the tube tremolo provides everything from subtle movement to deep, vintage-style pulsation. Both effects are footswitchable for convenient control during performance. A three-position EQ switch offers Full, Natural, and Low Cut settings, allowing players to tailor the amplifier's response to different guitars and playing styles. Built with premium components including carbon composition resistors, Mallory capacitors, cloth wiring, and custom USA-made transformers, the Atomic Space Tone reflects Swart's commitment to traditional amplifier construction. A solid pine cabinet houses a 12" Mojotone BV-30H speaker, delivering excellent projection and a full, responsive sound from this compact 5-watt combo.
