Vintage 1975 Systech Phase Shifter, Refurbished

Up for sale is a vintage 1975 Systech Phase Shifter, an uncommon mid-’70s effect with a distinct, understated analog phase character. This unit has been professionally refurbished, tested, and played, and is performing exactly as it should.

Service & Condition
• Fully serviced at Mad Slav Amps in Beaverton, OR
• All jacks are tight
• Switches engage cleanly
• Pots are smooth with no scratchiness
• Solid, heavy-duty 1970s build quality

Power Convenience
Includes a DC adapter pigtail, allowing you to use a standard Boss-style center-negative power supply, much easier than the original power setup.

Tone
This pedal delivers a subtle, vintage-style phase effect, adding gentle movement without the overly deep or swooshy sweep found in other designs. Ideal for players who want a more restrained, classic modulation texture.

It also allows you to switch between two preconfigured sweep speeds. From subtle phasing to full Lesli-like effect.

Demo Video
A demo video is included in the listing so you can hear exactly how it sounds before buying.

A nicely restored and great-sounding piece for anyone who enjoys unique 1970s gear.
