Overview
The ADDAC121 Humbucker is a module equipped with a standard humbucker-style pickup. It captures the vibrations of the strings stretched on the ADDAC120s Four Strings series.
The pickup has a built-in preamp that amplifies the captured signal to synth level. This lets you send the output directly to other modules such as VCFs and VCAs as a Eurorack audio signal.
The panel provides the following controls:
TONE: Adjusts the tone.VOLUME: Adjusts the output volume.LOW/HIGHgain switch: Switches the gain for saturation.
Output is taken from a single OUTPUT jack.
The pickup height can be adjusted with the mounting screws. The pickup section can also be detached and used handheld.

Background of Development
The ADDAC120s Four Strings series is a group of modules built around the idea of using physical strings as a creative medium. It consists of multiple modules that handle the strings themselves, as well as various approaches to the strings and sound generation.
The ADDAC121 Humbucker is the pickup module within that series for taking string vibrations out as an audio signal. It's designed to bring the same mechanism as an electric guitar pickup into a Eurorack system.
ADDAC120s Four Strings Series
The Four Strings series is available both as individual modules and as bundle systems. Our shop carries only the frameless ADDAC120BS Strings Basic System. If you'd like a larger setup, please consider adding other modules from the series separately.
Modules / Frames
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.
Four Strings Systems (Bundles)
Bundle pricing works out cheaper than buying the modules individually. Since the modules included in a bundle are essentially required to produce sound, we recommend starting from a bundle and adding other modules to it.
