ST-6V6se Info
5W Class A  • Single-Ended • 6V6/6L6
Tube Rectification • Pure Tone Goodness


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. More Info

5W SE Class A • TRIODE REVERB 6V6/6L6 Tube Rectified • 14lbs of Tonal Bliss w/Swart Reverb

Our new favorite at the shop!  The Space Tone ATOMIC JR is the famed ST-6V6se with a dedicated triode reverb stage utilizing the 12DW7 fed into a spring tank for amazing reverb emanating from this little 14lb beast. The circuit remains uber simple for the best touch sensitivity, tone, and responsiveness. Like all Swart Circuits, it Includes Tube rectification utilizing the GZ-34 or NOS 5Y3.  Features volume, tone, and "Space" control.  There will be a unique-to-Space Tone ATOMIC JR switchable gain option in place of the 6V6se feedback switch. It will have a 4ohm output transformer and come stock with the Weber Signature 8 Ceramic. The tweed covered pine cab will resemble a baby AST with light tweed and dark side panels. Other covering options are available. More Info

5W SE Class ATube Reverb
12" Speaker
6V6/6L6Glorious Breakup w/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, 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
(optional Dark Tweed & original STR Cab)

STR-Tremolo
5W SE Class ATube Reverb
Tube Tremolo 12" 6V6/6L6 Creamback, BV-30, Celestino Blue

This is our new favorite go to option, the latest amp that is causing all the buzz and intrigue, so much so, it was back ordered before #1 had even left the shop.  And who wouldn't want all the amazing tone and compelling breakup of that Swart single-ended, low watt STR glory with all tube reverb AND tremolo?  Indeed.  Bottom line, it's another great little amp with excellent swirling cleans moving into that great breakup and sweetness all the Swart amps are known for.   This is essentially much of the 5w, single-ended Class A STR-Tweed circuit with a unique 3-way EQ switch that is very handy along with this tube tremolo so addictive in the AST.  Yep, it's Cathode Biased for no users adjustments  with tube sub/rolling.  Like all Swart's, can run the 6V6 and 6L6.  Bring in ZERO NEGATIVE FEEDBACK for that open, quick, touch sensitive sound.  Don't forget the 5AR4/5Y3 Tube rectification for the amazing lack of harshness combined with the wonderful sag and compression when needed.  Comes with the Mojo BV30, or the excellent CREAMBACK, one of our favorites... but LOVES the Celestion Blue Alnico, too (Tux Cab w/Blue is Killer)!  Available in Tuxedo 60s covering or TWEED with dark sides.

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.

The Swart Antares
        18-22W  • 6V6/6L6 • Point to Point • Tube
         Verb/Trem • Tube Rectification • Shop Favorite

Introducing The Antares, Michael Swart’s latest all tube, point-to-point, hand-wired twin 6V6/6L6 amplifier. The Antares shares the legendary Atomic Space Tone’s attitude while being designed for those who crave a bit more headroom, bottom-end foundation, and bigger verb, while utilizing top mounted controls. Imagine the hallmark Swart 3D holographic, harmonic richness (anti syrupy or slow), partnered with that Swart transparency and touch sensitivity. Push it harder and you get that amazing breakup. An Antares owner noted, “The bottom end is really rich and hefty but still composed while the cleans are so sweet, clear, and vocal; push hard for that lush breakup.” The circuit features all-tube reverb and tremolo along with tube rectification; no solid state hardness or glare with this beast. Includes 3-Way EQ and high/low inputs to match guitar output. All pine, finger-jointed, hand-made, tilted back baffle.

ALL NEW ALTAR TO TONE ~ NOTHING LIKE IT !
Swart SST-30 Info
Tube Reverb/Trem - Master Vol - 4x6V6/6L6 ~ 30W

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, the SST-30 head and matching, custom tweed 2 x 12 Space Tone Cabinet, possibly one of the neatest cabinets we've seen, housing two Celestion "Creambacks" 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... More Info

 

 

 

 

 

Swart ST-45 Head
Tube Reverb/Trem - Master Vol - Twin 6L6 POWER

It's finally in production after the long wait but like a fine wine, it's more than worth it. The all new SPACE TONE FORTY-FIVE, or ST-45, is a first for Swart Amps on a number of fronts. It's our first 45 watt amp that is built and dedicated to the 6L6 tube, this via our first production Fixed Bias circuit to get the MOST out of this great tube. It's our first offering with separate bass and treble controls. Bottom line, this amp just has STELLAR CLEANS, so sweet and alluring, with no trace of the mechanical. Picture an AST on clean steroids. This amp really nails that elusive harmonic richness while still sounding open and transparent. The real kicker? It's actually as beautiful as it sounds, with another first for us, a full convertible HEAD cab that can be removed to show this beast off in full glory. IT's an aesthetic masterpiece mated with the easiest access to tube rolling fun you'll ever find. The cab is secured with four heavy duty latches. This amp made Buddy Miller reach for ye olde checkbook after only a few minutes playing at NAMM. Can be paired with matching 2x12 or 1x12. The 2x12 with CREAMBACKS is a winner but so is the 1x12 Gold or Cream. More Info
