Space Tone 6V6se
5W Class A - Single-Ended - 6V6 - Tube Rectified!

This is the amp that started it all.  The Swart Amplifier Co Space Tone 6V6se arose out of musician/recording engineer Michael Swart's attempt to get the most tone and soul from a small, easily manageable package for home/studio use. 5w of pure Class A tone with a breakup and natural tube distortion that is unequaled in modern amplification. Will play 6V6 and 6L6 and is Cathode Biased, so no biasing hassle. The ST-6V6se is now housed in an excellent finger-jointed cabinet covered with Lacquered TWEED. It's an instant Classic & Michael Swart favorite. Simply put, this is a KILLER amplifier. This circuit is the heart of Swart Amps: It's all about The Tone.

In just a handful of years, the Swart Atomic Space Tone has received some of the most glowing raves of ANY amplifier in recent memory.

This amplifier has 20w of twin 6V6 power in high Class A biased AB and brings some of the most soulful, rich, near three-dimensional tone you have ever heard. This has to be one of the most expressive amplifiers made to our knowledge, and we've tried more than a few.  TUBE REVERB and TUBE TREMOLO, something virtually nonexistent in today's marketplace, is just part of the picture. Includes a 12" Custom British Vintage Series BV-25m that screams TONE with body and soul; This amp has excellent breakup (wait till you hear the samples). This all new circuit is housed in a lacquered TWEED pine cab with dark Tweed panels. This amp is in its own league.

AST Head Mk II
& 1x12 Cabinet

ALL Tube Verb/Trem - Master ~ 6V6/6L6/EL-34!

The AST Head MkI Limited Edition sold out in a record 45 days. What to do? Get Michael working on a second version, this time designed from the ground up to be run as a head, with the added advantage of a MS designed defeatable Master Volume that can be bypassed for the purist! This is the FIRST Master we have liked in a combo as it does not leech the tone and bottom end. The new head can now run 6V6, 6L6, and even the EL-34. It's the same great AST circuit that has brought accolades from around the world, except now more flexible than ever! The AST Head II can push 4/8/16ohm cabs and has two outputs. The matching 1x12 cabinet comes stock with the Mojo BV-25 but can be purchased with speaker of choice. As always, the finger-jointed, lacquered tweed, pine cabs are first rate. This is destined to be another classic. More below.

The Ultimate AST 6V6/6L6 for the Gigging PRO
Swart and Greg V have teamed up again, except this time in the Design Studio. Introducing the Swart AST PRO, the answer to the professional musician's need for the AST with a nod to life on the stage and road. Take the amazing AST circuit and drop the beast into a cabinet with a bit more depth for some extra bottom, a recessed chassis for knob/switch protection from mishaps, and a bit more room for more speaker options. Then add the new larger port for more breathing room and the addition of an on-the-fly switching external output on back, making driving another cabinet as easy as plug in, and you have the amazing AST PRO, the new Swart offering ready to take you beyond. Comes with your choice of speaker, including the legendary Celestion G12H Heritage UK or the knockout tone monster Celestion Gold 12 Alnico. Pair this monster with our 2x12 cab and you have a host of options that would stir the head and the soul...

5W SE Class A - Tube Reverb -
12" Speaker
Glorious Breakup with Cleans Switch!

Take the original, ever popular, Class A, single-ended 5w ST-6V6se and pump it with steroids via another gain stage, killer tube reverb, and a 12" speaker and you have the new STR-Tweed, quite possibly the most FUN Swart amp to play yet. And the beast runs 6L6 & EL-34, too! This is truly a low watt monster and I cant stop wiping the grin off my face. Literally. This zero feedback circuit gets the added control of a switch letting you bypass the extra gain stage for more available cleans, and all with that great tube reverb that Swart has become known for. This truly might be Swart's most raw, big toned amp, all housed in our finger jointed pine cabinet in lacquered tweed (also available in optional Dark Tweed & original STR Cab)

Super Space Tone 30
Tube Head & Cabinet

  Tube Reverb/Trem - Master Vol - 4x6V6/2xEL-34 ~ 30-35W!

You loved the AST Head, so much so, we sold out of the Limited Edition run before we thought we would. After a line formed, asking us to extend the run, we told them to be patient. Michael loved the Atomic Space Tone in both the combo & head version but felt the need to up the stakes one notch, adding another pair of 6V6, the tone~soul valve of choice, this combined with a Master Volume and a number of tweaks to the circuit. Enter the all new, totally unique, Super Space Tone 30 head (SST-30) and matching, custom tweed 2 x 12 Space Tone Cabinet, possibly one of the neatest cabinets we've seen, housing two classic Celestion G12M "Greenbacks" behind the vintage grill. The combo is a knockout but each stands equally well alone.  We've found there's a "Hear it, gotta have it" thing going on. Don't say we didn't warn you...
