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 video game 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 Frequency knob. 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.
