Swart Star-Base 1
Swart · amplifier
Swart Amplifier Company built its reputation on boutique tube combos steeped in lush spring reverb and vintage American tone, most famously through the Space Tone series, and the Star-Base 1 appears to extend that hand-built philosophy into bass amplification. Swart's amps are known for point-to-point or turret-board construction and a warm, vintage-voiced character rather than modern high-headroom cleanliness, and a bass-focused release under the Swart name would likely carry that same tonal sensibility into the low end. Specific wattage, speaker configuration, and control layout for the Star-Base 1 aren't confirmed from available sources.
