    An Expressive Double Filter Fuzz

    What does “expressive double filter fuzz” even mean? Well, there are two filters pushed by a fuzz that opens up to more control via an expression pedal jack.

    PRE (P) controls the amount of FUZZ pushing into the filters. More volume pushes the filters to open up faster.

    FILTER 1 sweeps the first filter from a gulpy, swallowed up sound to a fly buzzing in your brain grind. You can turn this filter OFF via the TOGGLE, allowing the FUZZ to hit FILTER 2 unobstructed.

    FILTER 2 (F2) sweeps an envelope filter. As one moves the F2 pot clockwise, he/she/they can hear the “vocal/vowel quality” of the filter change. With more volume from PRE, the envelope opens faster.

    VOLUME (V) controls the output level.

    When the left MOMENTARY FOOTSWITCH is fully depressed and held down, the frequency range of the envelope filter (F2) immediately changes. Think of a wah going from toe-down to heel-up via a footswitch.

    The EXPRESSION PEDAL overtakes the PRE (P) pot and allows one to control how much fuzz hits the filters. Almost turns the pedal into a wah that changes the vocal quality and funk/feel of the overall sound. Get weird with it!

  • Hypersleep

    EAE Hypersleep SBS Reference

    The Electronic Audio Experiments Hypersleep is a solid-state analog reverberator. It evokes the immediate acoustic reflections of metal and tile, but with a darker timbre and a ringing, fluttering decay—forgoing epic atmospherics in favor of liminality.

    At the heart of the Hypersleep is the unusual and obsolete MN3011 bucket brigade device. Unlike other BBDs with one input and one output, the MN3011 uses an array of staggered delay outputs to produce a smeared-out echo. Feeding this echo back upon itself produces a reverberant texture. The reverb length can be modulated via the onboard LFO for atypical chorus and vibrato effects, or the haunting sound of a room changing size in real time. As always, careful signal conditioning ensures that Hypersleep is friendly to any instrument or line level signal source.


    Level – overall effect level, gracefully overloads at higher settings (Note: labeled as Drive on some units)

    Space – delay time of the BBD, simultaneously controlling six taps on a single delay line

    Mix – blend of clean and effected signals, from full dry to full wet

    Feedback – increases the decay time of the reverb, will self-oscillate at extreme settings

    Rate – modulation rate, from imperceptibly slow to nearly audio rates

    Depth – modulation depth, from subtle vibrato to warped pitch bending

    Additional features include buffered bypass soft-touch relay switching, 9V center negative power (180mA current draw), top-mounted jacks.

    All Hypersleep units carry a lifetime warranty tied to the original owner.

    Bypass: Relay switching with FET-input op amp bypass buffer

    We recommend a regulated, isolated power supply rated for 200mA minimum. Our pedals do not accept batteries. Use of an incorrect power supply may cause permanent damage.

  • Don’t have the words, can’t stay silent

    We have been reflecting on ways we can be allies, be supportive and bring about positive change. We will be listening, learning, finding creative ways to help. We will be supporting artists and organizations committed to equality and ending injustice.

    Resources to Support the Black Community

    We recently saw this 2015 video for “Cry No More.” Was transfixed the the entire time. A powerful performance.  The words Rhiannon Giddens  wrote on her YouTube page from 2015 are just as relevant today as they were then.

    “The massacre at the Emanuel AME church in Charleston, South Carolina, in June is just the latest in a string of racially charged events that have broken my heart. There are a lot of things to fix in this world, but history says if we don’t address this canker, centuries in the making, these things will continue to happen. No matter what level privilege you have, when the system is broken everybody loses. We all have to speak up when injustice happens. No matter what. And music is one of the best way I know to do so.”
    —Rhiannon Giddens

  • Family Photo


    Voltron and Friends 1Voltron and Friends 2


    Assembling the perfect pedal board is kind of like forming Voltron. You take these disparate elements and create a mighty, cat-robot defender of the galaxy. Or something like that.

    I was inspired by a recent Instagram post by S+K pedals. A collaboration with Electronic Audio Experiments wired up inside an etched enclosure depicting Voltron.

    I thought, hey! I have some S+K and some EAE and Voltron. So here is a little family photo of those guys and related builders, Fuzzrocious and Nerd Knuckle. Friends that often collaborate with John & Scot. All of whom we here at SBS have massive respect for.

    The effects pictured here are for sale (Sorry, but Mr. V. is not.). Send us an email for details.

  • In Stock, Ready To Ship

  • Music in the Time of Quarantine

    Hey Everyone,

    Much like you, we are doing our best to stay home, stay safe, and keep positive.

    It has taken some time to figure how best to move forward. Is that even possible? Well, we gotta try.

    So much of what Stompbox Sonic does hinges on face-to-face consultations and community events with builders & musicians. So we need a new way, a more digital, less tangible way of doing that. So stay tuned. Before long we’ll have some online ways to bring the effects- lovin’-sound-craftin’ people together.

    In the meantime here are some resources if you need help or are looking to help:
