Body Synths Laboratory is a dual-channel analog effects processor and feedback synthesizer — the second instrument from Body Synths, developed in collaboration with Andrey of Berlin-based pedal company akkusativ. Announced at Superbooth 2026 in Berlin, planned for release in 2026. Pricing and full technical specifications have not yet been announced.
Four feedback paths and two channels — the instrument's core
At the center of the Laboratory are four feedback paths. External signals can be routed through them for delay repeats with grit and texture, or the system can be pushed into self-oscillation — with no input signal whatsoever. Each of the two channels offers three voltage-controlled parameters: Gain (from silence through amplification to saturation), Delay (based on the PT2399 chip — the same karaoke delay chip that produces characteristic warm signal degradation at longer delay times), and a Resonant Filter switchable between Low-Pass and High-Pass modes. Running both channels in series creates a Band-Pass filter response. Combining both channels opens up multi-tap and ping-pong echo configurations. A clipping stage at the output of each channel adds compression and distortion when driven hard — ranging from subtle saturation to full signal collapse.Modulator, CV and the character of the instrument
A global Modulator operates as either an LFO or an Envelope, with two positive and two negative CV outputs — the basis for building tremolo, vibrato, chorus, moving stereo filter sweeps, and modulated delays. The Laboratory is primarily an analog device: the delay section uses the digital PT2399 chip, but the instrument contains no microcontroller and runs no software. Two independent channels generating stereo feedback noise — which the manufacturer describes as a rarity among feedback and experimental noise instruments. Conceptually similar to the no-input mixing board technique, but in a purpose-designed enclosure with a precision signal path.KEY FEATURES
- Dual-channel effects processor and feedback synthesizer — stereo feedback noise without any input signal
- Four feedback paths — delay repeats, texture, self-oscillation
- Per channel: Gain (VCA), Delay (PT2399), Resonant Filter (LP/HP) — all voltage-controlled
- Channels in series: Band-Pass filter; in series or parallel: multi-tap and ping-pong echo
- Clipping stage at each channel output — compression and distortion under hard drive
- Cross-feedback between channels — driving channels into each other's saturation
- Global Modulator (LFO / Envelope): 2x positive CV output + 2x negative CV output
- Analog signal path — no microcontroller, no software
- Developed in collaboration with akkusativ (Berlin)
- Planned release: 2026 — pricing and full technical specifications TBA
