Acorn Amps Launches the ADHD Filter Synth Fuzz

Acorn Amps Launches the ADHD Filter Synth Fuzz

The ADHD, or Adaptive Droning Hyperfuzz Device, is a glitch, filter, bit crushing, octave, square wave guitar synth oscillator disguised as a fuzz pedal.


The newest creation from Acorn Amps, the ADHD, is a pedal that’s hard to pin down into one category of stompbox effects. The ADHD, or Adaptive Droning Hyperfuzz Device, is a glitch, filter, bit crushing, octave, square wave guitar synth oscillator disguised as a fuzz pedal. An adjustable square wave oscillator accompanies a rambunctious fuzz circuit to create a wildly interactive guitar or bass guitar effect. 8-bit vintage videogame tones become searing octave leads with the turn of the five control knobs on board the ADHD and the synth noise oscillator can be controlled using an external expression pedal or tuned by hand with the Frequencyknob. The Acorn ADHD is assembled using a voltage-controlled timer that blends with the gain control of an LM386 amplifier IC chip to produce interactive and layered bit crushed octave-up-and-down fuzz tones that can be sculpted even further along the frequency bandwidth with the tone/filter control. Transform your guitar into an expansive fuzzy synthesizer with the Acorn Amps ADHD pedal.

Features Include:

  • Five shapable controls to design your own fuzzy, synth-y soundscapes
  • Expression jack to control the oscillation circuit externally
  • Balance control to blend the synth oscillator with the fuzz circuit
  • Pedalboard-friendly compact design assembled in a 1590B aluminum enclosure
  • True bypass and powered by standard 9V DC pedal power. Consumes less than 30mA of current

The ADHD Fuzz is $149.00.

English singer-songwriter Robyn Hitchcock is as recognizable by tone, lyrics, and his vibrantly hued clothing choices as the sound of Miles Davis’ horn.

The English guitarist expands his extensive discography with 1967: Vacations in the Past, an album paired with a separate book release, both dedicated to the year 1967 and the 14-year-old version of himself that still lives in him today.

English singer-songwriter Robyn Hitchcock is one of those people who, in his art as well as in his every expression, presents himself fully, without scrim. I don’t know if that’s because he intends to, exactly, or if it’s just that he doesn’t know how to be anyone but himself. And it’s that genuine quality that privileges you or I, as the listener, to recognize him in tone or lyrics alone, the same way one knows the sound of Miles Davis’ horn within an instant of hearing it—or the same way one could tell Hitchcock apart in a crowd by his vibrantly hued, often loudly patterned fashion choices.

After 26 years, the seminal noisy rockers return to the studio to create Rack, a master class of pummeling, machine-like grooves, raving vocals, and knotty, dissonant, and incisive guitar mayhem.

The last time the Jesus Lizard released an album, the world was different. The year was 1998: Most people counted themselves lucky to have a cell phone, Seinfeld finished its final season, Total Request Live was just hitting MTV, and among the year’s No. 1 albums were Dave Matthews Band’s Before These Crowded Streets, Beastie Boys’ Hello Nasty, The Miseducation of Lauryn Hill, Korn’s Follow the Leader, and the Armageddonsoundtrack. These were the early days of mp3 culture—Napster didn’t come along until 1999—so if you wanted to hear those albums, you’d have to go to the store and buy a copy.
