An all analogue Frequency Shifter with all the wrappings

The Frequency Shifter (red) is a powerful and experimental analogue processor. This standalone design springs from my Quadrature Sine and its Frequency Shifter Expander modular designs – all wrapped up with circuitry & features to allow it to fit snugly into more regular studio processing roles. It will transform your audio streams in otherworldly ways – clangorous, tonal, phased, stereofication and swoosh.
