Ross Phaser Original Phase Shifter Vintage 1979 Modified Guitar Effect Pedal

This is a used Ross Phaser cosmetically in fair condition and is fully functional. No box, power supply, or batteries. Will run off a standard 9v adapter or a 9v battery. Has wear as pictured. Original power input was removed and a modern 9v input was added on the other side of the pedal. Has a couple holes exposed in the enclosure, the top one being an abandoned project. Modifications are added LED, true bypass switch, new battery clip, and power input conversion.
