Used Instuo TANH Modular Synthesizer Rackmount

This Instro TANH modular synth module is a compact utility designed for shaping and transforming control voltages and audio signals inside a Eurorack system. Built around a hyperbolic tangent waveshaping circuit, TANH excels at soft clipping, saturation, and signal conditioning while remaining small and straightforward. The panel layout keeps things intuitive, making it easy to integrate into both minimal and complex modular setups.

This module is especially appealing for users looking to add subtle warmth, controlled distortion, or dynamic response to oscillators, envelopes, and modulation sources. The TANH curve is well known in synthesis for its musical behavior, gently compressing peaks rather than harshly clipping them. That makes this module useful for taming hot signals, adding harmonic richness, or introducing analog character without overpowering the rest of a patch.

This module has been tested thoroughly in store to ensure proper operation. Please take time to closely review the photos for full condition details, as minor cosmetic wear may not be specifically described. We buy, sell, and trade used gear every day, so feel free to reach out if you are looking to trade toward something new or expand your modular system.
