Korg PS-3300 FS

CurrentReleased 2025

A made-to-order recreation of Korg's 1977 PS-3300, one of the rarest polysynths ever built. Every one of the 49 keys has its own oscillator, filter, amplifier and envelope in each of three layers, so it is fully polyphonic analogue with semi-modular patching and per-note microtuning. A collector's and studio instrument at a collector's price.
