Traigh Transistor Ladder Filter

Instruo Traigh

With their Traigh module, Instruo sought to construct a worthy successor to Bob Moog’s classic transistor ladder circuit designs. Consequently, this endeavor resulted in one of the squelchiest 24dB filters in all of eurorack! True to its lineage, Traigh specializes in the creation of warm, punchy sounds. It features a 3 channel fader-controlled mixer for summing audio signals and can be pushed into self-oscillation under the right conditions.
