"I might as well confess that I'm really an old school guy, totally hooked on the character of vintage stuff. From my 1912 bungalow house to my VW bugs, blue or black Chuck Taylors, tube amps, classic motorcycles and old vintage longboards. I like just about everything from the '50s and '60s." - Michael Swart (Tone Report interview) 

Michael Swart has been building beautiful, vintage-minded amps down in Wilmington, NC for quite some time now and we couldn't be happier to now represent his killer line of amps and pedals! Swart players include Jeff Tweedy (Wilco), John Flansburgh (They Might Be Giants), Greg V, Matthew Sweet, etc...

In some respects, the STR-Tremolo is like a mini version of Swart's lauded (and larger/louder) Atomic Space Tone amp. Powered by a single 6v6 tube and clocking in at 5 watts, this gorgeous little amp as all about killer breakup at lower volumes. Don't get us wrong, the STR-Tremolo sounds killer when set to cleaner tones as well, but the breakup on this little guy is just huge.

A Swart hallmark, the reverb and tremolo on the STR-Trem is incredible. Tube driven, lush, utterly inspiring...and did we mention the way this amp breaks up? Add in a mini toggle switch which helps dial back some of the bass when cranked or you can add it back when playing clean or at lower volumes, and you've got one hell of a fun amp for home, studio, or small gig use! 

Like all Swart amps, the STR-Tremolo utilizes the Swart's philosophy of minimal controls for the least amount of complexity, something that's instrumental to great tone. We concur, this is yet another killer sounding, home-friendly amp from the good folks at Swart!
