SynapticGroove / Slackjaw / 2014 / Effect For Sale

SynapticGroove SlackJaw OD/Boost/Fuzz 

The SlackJaw offers players of every genre an OD/Boost/Fuzz pedal without complication. Handling single coils, humbuckers and solid state or tube amps with equality, the Slackjaw is composed of the best voicing that overdrives, boosts and fuzz pedals have ever offered — in a singular design. Our sophomore effort packs an astounding array of tonal features and compliments the Snapperhead perfectly…or any other overdrive/amp for that matter! In addition to being 100% handmade in the U.S.A., it comes with these defining elements:

A voice range from nearly clean boost to warm saturation to hairy fuzz without tone coloration or signal degradation
Level and Gain controls that make dialing in perfect tone painless
Three-way switch for compression, boost and saturation
Two-way switch for bass boost/reduce
A robust hand-sanded/hand-painted enclosure
The absolute best components available on the market
The SlackJaw has already earned the embrace of Nick Perri, Richard Fortus and Jefferson Angell, who are jamming the pedal on their tours and taking it in the studio for those late night creative sessions!

Please check out some audio clips below (courtesy of the talented Nick Perri) and we’ll have video clips up soon! The SlackJaw graphic credit goes to William Harrison (Thanks Dad!)

 Live your imagination, not someone else’s.

SynapticGroove is culled from 30+ years combined experience in the music industry, and well over that in life.  Our goal is to enable great art.  Period.  Great artists need a multitude of characteristics: determination, vision, talent, heart.  Likewise, all artists need tools to help express their vision.  We make these tools and use these tools.  We hope that all of you get many years of creative service out of them and pass them on to the next generation.  Remember, the only true competitor you have, is with yourself.

We are SynapticGroove, a company founded on the ideal that art is what makes life meaningful.  A great visionary once steered his company through the intersection of where art and technology meet, changing millions of lives, for the better, in the process.  We aim to do just that.  When someone hears sound in color or tastes ideas, it is often referred to as synesthesia.  By engaging all of the senses, we lead a fulfilled and satisfactory existence.  Music is the only art form that transcends time & space, religion, ethnicity and cultural boundaries.  There is nothing else in the world that stirs our emotions and memories like music.  It is amazing.  We want to be a small part of that magic and mojo that is musical creation.
