DeArmond Model 1900 Pedal Phaser 1974 - Black

Vintage 1974 DeArmond Model 1900 Pedal Phaser

NOTE: Please be aware that while this unit came with a factory-designed bypass, the switch you see on the side is a functional aftermarket addition installed in the mid-1980s. This toggle acts as a hardwired true bypass, completely eliminating vintage circuit hum and preserving your pristine clean tone when the effect is disengaged.

NOTE: It is missing one of the original rubber legs.

Up for sale is a rare, highly expressive piece of original 1970s analog effects history: a DeArmond Model 1900 Pedal Phaser. This specific unit features an internal chassis date stamp from December 1974, placing it right at the heart of DeArmond's classic American-made production run.

Unlike typical knob-based phase shifters of the era, the Model 1900 utilizes a heavy-duty, wah-style treadle chassis. It delivers an incredibly organic, fluid, and versatile 6-stage analog phase sweep that you manipulate completely by foot. You can rock the pedal dynamically to vary the speed and sweep or park it in any position to lock in a striking "cocked-filter" vocal texture.

Condition & Functionality:

• Electronics: Fully tested, cleaned, and 100% operational. The internal circuit board and components look absolutely perfect and pristine.
• Performance: Plays exceptionally well with an incredibly lush, warm, and highly interactive sweep.
• Cosmetics: In Very Good vintage condition (as shown in the detailed photos). It shows some honest, light cosmetic wear consistent with a 50-year-old pedal, but it remains structurally rock solid.
