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.

CuNiFe-driven Wide Range pickups and a 7.25" fretboard radius make this the most period-correct Thinline since the original.

Awesome, alive, and individual Wide Range pickup sounds. Great neck. A 7.25" fretboard radius. Light weight. Period-authentic 1 meg pots.

Taper on 1 meg pots not very nuanced. Less-than-plentiful ash supplies could mean odd grain matches on natural-finish guitars.

$2,399

In the 50 years since their big, chrome covers first reflected a hot stage light, Fender’s Seth Lover-designed Wide Range humbuckers have gone from maligned to revered. The guitars built around Wide Range pickups are legends in their own right, too. Keith Richards’ Telecaster Custom is synonymous with the Stones dynamic and adventurous late-70s-to-early-80s period. Scores of punk and indie guitarists made the Telecaster Deluxe a fixture of those scenes. And Jonny Greenwood almost singlehandedly elevated the Starcaster from a curiosity to an object of collector lust. The fourth member of the Wide Range-based guitar family, the ’72 Telecaster Thinline, lived a comparatively low-profile life. Yet it is a practical, streamlined, uniquely stylish, and multifaceted instrument with a truly original voice—qualities that are plain to see, feel, and hear in this new American Vintage II incarnation.
