The DOD Phasor 201 recreates the vintage analog phase sound of its predecessor, also called the 201 but housed in a yellow chassis rather than blue. The new Phasor 201, however, comes with a variety of modern updates, such as a super lightweight body and modern 9v power supply input. But don't worry, the new DOD Phasor 201 still sports only one knob to dial in your depth and speed with supreme ease. The DOD Phasor 201 Reissue is a subtle, modern update to that original analog phaser sound.
