Swart STR Tweed
Swart · amplifier
The Swart STR Tweed is the tweed-covered version of the STR Space Tone Reverb, a 5-watt single-ended combo with a 12-inch speaker carrying the company's valve reverb and tremolo. At 5 watts through a twelve it reaches saturation at low volume while retaining more low-end body than the smaller-speakered amps in the range, which is the practical argument for this format. Swart build everything hand-wired with high-grade components. It suits blues, roots and studio players who want genuine valve breakup and ambience without stage volume.
