259 Classic Reissue – Programmable Waveform Generator – PREORDER


Shipping: Spring 2024

The Buchla reissue of the Model 259 reproduces the original, unmatched sound with expanded tracking up to 10 octaves for greater sonic potential. The 259 features all-analog timbral circuitry, so it suffers none of the aliasing of digital wavetables. You get fully voltage-controlled modulation of pitch, amplitude with a multi-octave range owners of the original could only fantasize about.
