Products / Product List

A matched pair of Headstock (17HP) and Bridge (6HP) panels with 4 locking tuners for easy string installation. Passive stainless-steel construction raises strings high enough to fit other modules underneath. Includes a string set (.010–.046), bow arch attachment, and small resonators.

A 10HP humbucker pickup module with an integrated pre-amplifier delivering synth-level output. Features TONE and VOLUME knobs plus a LOW/HIGH gain switch. Height-adjustable via mounting screws; the pickup can be removed for handheld use.

A 14HP quadraphonic pickup with 4 independent coils — one per string — each with its own pre-amplifier, VOLUME knob, and output jack (STRING 1–4), plus a MONO MIX output. All coils are hand-wound with Alnico 5 slugs, 44AWG polyurethane wire, and ~7.4kΩ per coil.

A 14HP plectrum module with one servo per string, triggerable via push-button, gate, or MIDI (USB + TRS). Offers Pluck mode (~20° swing to pluck the string) and Harmonic mode (~10° tap for harmonics). Up to 3 units can be daisy-chained.

A 10HP servo-driven mute module inspired by the Fender Mute (Jaguar/Bass VI). A foam pad lowers onto the strings to create a gentle dampening — a distinct tonal character different from palm muting. Passive module; controlled by an ADDAC124 Plectrums servo.

A 10HP module with a 7,000 RPM brushless motor spinning 4 magnets. When the motor RPM matches a string's resonant frequency or harmonics, the rotating magnetic field excites the string — similar to using a bow on an electric guitar. Speed is controlled by a SPEED knob and CV input.

A 16HP mechanical harness and sliding rail for a standard Ebow. The included Ebow is modified with the "PianoBow" mod (feet sanded down) so it slides freely below all strings without contact. Height is adjustable via thumb screws. Passive module; no power required.

An entry-level bundle including ADDAC120 Headstock & Bridge, ADDAC121 Humbucker, and ADDAC126 Rotary Exciter. Modules only; no frame included.

A standalone MIDI processor and macro controller with 32 macro knobs. Features a stackable MIDI processing engine, LFO modulation, and 14-bit MIDI for flexible routing and control across hardware and software setups.

16-channel, 16-bit MIDI-to-CV expander for the S32.

A small solar-powered standalone sound instrument by Meng Qi. Three CD4093-based oscillators are played by shading the solar panel and touching the gold contact points; it clips on to be worn and sounds through a built-in speaker.

An 8HP multimode analog filter inspired by the EDP WASP. Low-pass, band-pass, notch, and high-pass are available simultaneously on individual jacks, while the main output adds filter-type selection, switchable distortion, and phase inversion. Cutoff is voltage-controllable via a CV input with an attenuator.

An 8HP voltage-controlled transition / macro controller that sweeps five CV channels at once from a single slider (or CV input). Each channel has Minimum, Span, and a direction switch, so one gesture moves five destinations with individual ranges and directions.

A 2HP expander for the Time Machine with 9 linear VCAs. Each slider passes unity gain at +5V with no cable, or works as an attenuator when patched. Requires Time Machine firmware v1.1.1.

Converter panel set that lets you install 3U modules (up to 4HP wide) into an Intellijel-format 1U slot. Includes 3 panels and mounting hardware.

Analog multifunction module born from a collaboration between Weston Precision Audio and Trovarsi. Packs a discrete OTA state variable VCF, VCA, and dual envelopes (ADSR + AD/AR) into 12HP.
