What We Think

Condition: Used, Excellent

This Swart amplifier is a beautifully expressive, hand-wired Class A design that delivers rich, dimensional tube tone with remarkable feel and character. Its single-ended circuit, valve rectifier, and zero negative feedback create touch-sensitive response, while lush tube-driven reverb and tremolo add depth and movement at the tap of a footswitch. Built with premium components, point-to-point wiring, and a resonant pine cabinet, it feels alive and responsive at any volume. Compact yet powerful, this Swart is a thoughtful, enduring investment—crafted to inspire creativity and reward discerning players for many years to come.

Manufacturer's Description from Swart Amps

Yep, the STR-Tremolo will have the same soul and basic circuit as the STR-Tweed, just with:


The addition of a great tremolo stage

(along with a revised and more surf Zone Reverb Stage)


The addition of  a 3 way EQ Switch that makes

the STR-Trem more flexible


Available in the original STR "Tuxedo" 60s style

or the AST Style Tweed cab.

Push comes to shove, I think the STR-Tremolo does have a touch less gain than the STR-Treed as the Tremolo section will take place of the extra gain stage in half of the 12AX7.  On the other hand, it will still have much of the STR-Tweed's great tone, immediacy,  growl, and touch sensitivity.  Drop in the Atomic Boost, and you get it back and more.  I really dig this amp and have been playing it daily since we finally got it off the bench.
