**Better deal than modules bought individually**

Swell is a 14-HP valve harmonic filter at the crossroads of East and West: a precision analogue filter shaped by a Cold War-era military valve that sculpts timbre into new territories.

1. A Soviet military-spec subminiature valve, actively in the signal path

2. Precision 24dB/oct 4-pole analogue filter — musical, temperature-stable, and detailed

3. Full control over where and how the valve shapes your sound: mode, bias, gain, and placement

4. Split personality: from compressed warmth to untamed chaos — provoked by FM feedback or sheer resonance.

5. Self-oscillating VCO with 1V/Oct tracking — use the valve to sculpt the waveform itself
