Detected by its strong magnetic field emanating from the lunar crater Tycho, the TMA-1 was found buried 15 meters beneath the surface of the moon. The moment 9 volts of direct current hit the TMA-1, a powerful signal burst across the universe, searching for other devices of its kind. This is how the new fuzz pedal from Acorn Amplifiers came to be. The TMA-1 fuzz is a four stage transistor fuzz featuring a series of selectable diode clipping options. Germanium diodes, silicon diodes, and a bypass of the clipping diodes are switchable in two separate stages of the fuzz circuit, allowing for a vast array of shapable fuzz tones. A giant glass lens indicator glows red on the face of the pedal to remind humans of the impending singularity that threatens to doom mankind, and also to let you know when the fuzz is engaged.

TMA-1 Fuzz

With the Circuit Fuzz, Acorn Amplifiers has debuted the first effects pedal that provides a bonus effects pedal PCB right on the face of the pedal. Two for one! Perfect for the guitarist interested in building their first effects pedal or a seasoned tinkerer that mods every piece of gear they own. The removable PCB is a simple boost circuit that can be built into a separate pedal or incorporated into the Circuit Fuzz itself. Build instructions available on the ‘Boost PCB Build’ tab at the top of this page.

The Circuit Fuzz pedal itself is a deceptively simple yet versatile dual transistor fuzz that sweeps between overdrive, distortion, and fuzz tones with the turn of a single knob. Simplicity in design, yet versatility in action - these are the goals of each circuit designed by Acorn Amps and the Circuit Fuzz is no exception.

Last year we debuted the Transistor MIGFET 50P Preamp, a reinterpretation of the original Sovtek MIG50 guitar tube amplifier in pedal form. The response was amazing. Guitarists rejoiced as the sound of one of their most oft used amps was now available in a convenient pedal package. The one bit of feedback we received from the MIGFET was that users wanted MORE GAIN, so we popped open the hood and discovered a simple yet effective single component swap that delivers additional breakup while retaining the full tonal characteristics of the MIG sound. And thus, the MIGFET V2 was born. The MIGFET V2 uses JFETs in place of the 12AX7 preamp tubes in the original amp circuit. This gives the pedal the compression/sag response of a tube amp when you dig in on your guitar strings. The dynamic EQ has that classic Bassman tone stack shapeability that the MIG circuit employed and allows for a slew of easily tunable sounds. Turn the Volume low and raise the Master for clean preamp tones. Lower the Master and crank the Volume for more gain/breakup.

MIGFET Preamp V2

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.
