Swart AST Pro Tube Amplifier, 2012

Handbuilt in Wilmington North Carolina, the Swart AST Pro is a road-enhanced version of the Atomic Space Tone 18-watt, 1×12 inch speaker amp. Designed with guitarist Greg V, the AST Pro has a deeper, cabinet that allows recessing the amp chassis for knob and switch protection. Like the AST, it has a tweed covering with a dark lacquer stain. The rear panel has a larger port allowing a more open sound.

The Swart AST Pro uses a 12AX7, 12AY7, a 5AR4 rectifier and a pair of Electro-Harmonix 6V6GT power tubes. It produces 18 watts and also has reverb and tremolo! The back panel features knobs for volume, tone, Space (reverb level) and Intensity and Speed (the tremolo controls). The back also has a switch for Internal or External speaker (if connected) and this has been moved inside the cabinet.

This amp is in very good condition, and these models have a great sound. As a relatively low powered amp, it delivers a full, rich tone at a reasonable volume. It’s worth a visit to the Swart AST Pro page to listen to the Greg V audio clips.
