The Mullard OC44 Powered Atomic Boost - See Diagram
Pedals - Attenuators - LED Footswitch

NEW! 60s Treble Booster

Anyone that knows pedals knows the Dallas Rangermaster and the history behind it. Michael took one of the all time favorite gain boosters with that legendary tone and distortion and made it even more reliable and less prone to RF Bleed while still employing the much sought after vintage NOS Mullard CV7003 Transistor, a TIGHTER SPEC glass envelope OC44 made for Military applications. The key device to retaining this tone with boost is still here, just at a tighter tolerance..

The ATOMIC BOOST is an amazing match with the twin 6V6 ATOMIC SPACE TONE!

  • Vintage NOS Mullard OC44 "glass" Transistor hand selected and gain tested NOW WITH TIGHTER TOLERANCE CV7003, the Mullard SO-2 GLASS Military Spec OC44. These are TIGHTER TOLERANCE OC44 in SO-2 GLASS package

  • All Point to Point Wiring
    - No Circuit Boards

  • Toggle between Mid or full boost, optional high boost with the sacrifice of mid or full boost

  • Full bypass switching

  • Blue Power LED

  • Dedicated 9v battery operation for cleanest power and lowest noise

  • Sound goes from a semi clean boost to over the top creamy tube distortion

  • Lovingly Hand-Built by Michael & Kent

The ATOMIC DUO is a package that cant be loverlooked as the Atomic Space Tone and the Atomic Boost are just made for each other. The pedal does work amazingly with the other Swart offerings as well, though might be a touch overkill for something like the 6V6se.

The Mil-Spec OC44 at Tighter Tolerance

Atomic Boost

*UPDATE 3/2015
: We are out of the OC44 transistors, all gone. But we have now transitioned to the CV7003 which is the mil spec "Military" version of the OC44 and it's made by MULLARD as well. So in essence, you are getting a GLASS OC44 that is made to Mil-SPEC so a LOT more consistant. THIS IS THE MULLARD SO-2 GLASS VERSION, not the metal can TI version. From our research, we are 99% sure these are MULLARD made. We had thought of discontinuing the Atomic Boost but this transistor has been a big surprise and given the pedal new life.  It's actually a tighter spec with more differences between TWO OC44 then the OC44 and CV7003!  This is actually a VERY nice option. We're impressed and RECOMMEND IT HIGHLY.

Here is a picture of the CV7003 which in the glass version is very similar to the OC44, but with tighter tolerances. Consistency should be better between pedals.


The Swart FuzzyBoost is a hand-wired, point-to-point sonic blast to the past with some extra credit, Swart Magic thrown into the mix. This is no mass market, overseas circuit board, costs us nothing~you something, cloner pop.

Fuzzy boost allows you to slide anywhere from slight boost to over the top fuzz at any volume level.

  • Pre Volume Volume before it hits the circuit
    allows you to clean up or drive more intense Fuzz. This is a GREAT feature that you'll soon come to love.

  • Dirt Your main GAIN level for Fuzzoid Blast

  • Post Volume So you can get the distortion at
    any volume level from whisper to Blow Neighbor's
    Septic Brain.

And just as in the Atomic Boost, Swart FuzzyBoost features hand-picked Germanium Transistors.

Swart Night Light
Attenuator & Stereo Drive

FOUR Position Attenuator - excellent tone • defeatable light bulb filament compression stage w/bulb that lights blue when activated • Bypass for direct • Run TWO SWARTS from output of first • Hand wired • compact size • Blue night light glow • unlike any attenuator on the market • Designed to bring the sonics and breakup back to spouse pleasing levels • designed for AST, AST PRO, STR-Tweed, STR, Atomic Jr, ST-6V6se • Will work with amps 22w down (30w with bulb compression bypassed) • Designed for 4-8ohm Load






Smaller is better sometimes.  In this case, the all hand-wired Night Light Jr attenuator packs a punch in a tiny package. We wanted something to hide in the port of the ST-6V6se, Atomic Jr, STR-Tweed, and STR-Tremolo.   An attenuator that's more simple and bare bones, something designed for the low watt sect that brings that GREAT breakup without frequency loss, and something you can MOUNT and not fuss with, with minimal worry. It's here with the Night Light Jr. Comes with a linear full range volume pot and full bypass switch along with blue light within.

This little diminutive beast sounds sublime and even has some of the Night Light Blue Magic while at work.   Of course, less features than our original robust Night Light and really designed for mounting vs stand alone.  And you're talking a max of 15w.  But we're really digging this little beast and loving the way it brings that Swart Low Watt breakup at more manageable levels within the smaller combos for those in need.

The Night Light Jr has had runs of original black, sparkle, and now a cool vintage blue. The latest run is now shipping, ready to be mounted within our low watt amps or tossed within any 4-8ohm amp that is 15w or less.  The package comes with mounting screws.  For our amps, you can use the stock speaker cable to speaker and we recommend getting the shorter cable to run from the amp output.

Will be able to be custom ordered within our amps soon, too. Please contact your favorite Swart Dealer.

Hand-Wired   •   Mounting screws~easy install in cab   •   Designed for Amps 15w or Less   •   Perfect Low watt Solution   •    Full Bypass Switch    •    Linear Pot with wide attenuation range    •    4-8ohms Trans


UPDATE: New Night Light Jr boxes in BLUE just arrived so we're back in production. Please contact your nearest Swart Dealer for orders. Out of Sparkle Run.
