Acorn Amps ADHD
Glitch, filter, bitcrushing, octave, square wave, guitar synth oscillator — disguised as a fuzz pedal. The Acorn Amps ADHD is the most chaotic and most fun pedal I've featured on the channel. Welcome back to Edge of Breakup.
In this episode the Acorn Amplifiers ADHD takes center stage across three guitars — the Giordano Guitars '60s S-Model Strat, the 1967 Gibson ES-335, and the Frank Brothers Ultralight with Lollar El Rayo Humbuckers and Lollar Firebird on a Blender Pot.
ADHD stands for Adaptive Droning Hyperfuzz Device. It works like a two-oscillator synthesizer: one oscillator is your guitar signal converted to a square wave by the fuzz circuit, the other is an adjustable square wave oscillator that can be tuned by hand with the Frequency knob or controlled via external expression pedal. A voltage-controlled timer blends with the gain control of an LM386 amplifier IC chip to produce interactive, layered, bitcrushed octave-up-and-down fuzz tones that can be sculpted further with the Tone/Filter control.
Five knobs run the whole machine. Level handles output. Frequency tunes the internal oscillator — sweep it and the pitch of the synth tone tracks or clashes with your guitar depending on what you're playing, creating everything from locked-in octave doubling to pure noisecore. The pink Balance knob in the center mixes the two oscillators to taste — dialing back the synth side gives you vintage Octavia-style octave fuzz; pushing it to the opposite end and you're in pure square wave chaos. Threshold does the bitcrushing — counterclockwise gives spitty lo-fi gated fuzz, higher settings give full body. Tone adjusts the bandwidth of the fuzz-oscillator interaction.
Three guitars, three completely different tonal personalities through the ADHD. The Giordano single coils, the 335 humbuckers, and the Ultralight's El Rayo/Firebird blend each interact with the oscillator in meaningfully different ways. The Balance knob is the key to making this usable across all contexts.
