When you start with the pedal at its mellowest setting (with the fuzz/oscillator balance and tone fully clockwise), the signal feels vaguely boosted with throbs of low-level oscillation around it. The fuzz element becomes more fuzz-like, though, as you advance the balance. And along the way the threshold control (which sweeps between droning oscillations and gated ones) and the frequency dial (which adjusts the pitch of the oscillator) interact to create everything from vocal, vowel-y filter effects to crackling, irregular decay. Keeping the balance control on the clockwise side of noon enables you to foreground fuzz textures while harmonizing drones (that can be adjusted to pitch) and/or fractured articles of oscillator-driven chaos pile up around you. Don’t worry though. If you get in trouble, the gate or balance control can save you fast.
The Acorn ADHD is a musical puzzle—just the way modular synthesis can be. You’ll make ugly sounds as you decode its secrets. But the ADHD is full of beautifully funky, obscene, confrontational, and mysterious tones that can distinguish a guitar part or be the genesis of a whole musical idea or song. This is a pedal best used by turning off preconceptions and letting your mind drift. It could even become a very noisy meditation ritual. Just be sure to record the brilliant tones you’ll encounter along the way.
In a 2021 interview, a relatively overlooked low-wattage practice amp was revealed to be a studio's secret weapon for achieving wiry and aggressive tones for guitar, bass, and even drums and vocals. The latest release from Acorn Amplifiers, the Solid State Preamplifier, is a recreation of the preamp of that highly sought-after amp, which has been packed into a slim pedal enclosure and loaded with features. Also, without the added cost of the power amp circuitry, the Solid State Preamplifier is nearly half of the price of the original Acorn Solid State Amp/Preamp.
Features Include:
- Two foot-switchable tone channels - ‘normal’ for wiry, sparkling clean drive & ‘saturated’ for aggressive gain
- Toggle switch to add ‘thick’ low end, added gain, and a signal boost
- Pedalboard-friendly compact design assembled in a 1590B aluminum enclosure
- True bypass and powered by 9-18VDC pedal power. Consumes less than100mA of current
