1977 MXR Phase 100 Phaser Vintage Guitar Effect Pedal

Up for sale, a 1977 MXR Phase 100 vintage effects pedal in excellent condition and in perfect working order. This big brother of the Phase 90, famous for adding swirl, dimension, and warble to guitar and electric piano parts, the Phase 100 offers an even broader range of sounds. It was first introduced in 1974; this early example is the second iteration (featuring the block logo), first released in 1976. Along with the speed control there is a four-position rotary switch that selects between four different intensities, defined as preset waveform patterns.Tonally, it’s lush and dynamic, with a surprising amount of tonal versatility beneath the simple control scheme, powered by an internal 9V battery. The original CTS pots date to the 27th week of 1977. This particular unit is in good shape, with some light wear along the edges and bottom of the enclosure, plus a few scratches on top. The knobs are original, and the graphics are clean.
