The Smoothie is a phaser pedal based on the MXR Phase 45. It features a two-stage phaser driven by a simple LFO. The input signal is passed through a filter network controlled by two JFET transistors, which are powered by the LFO generated by IC2B. The input signal is then mixed before being outputted.

It is important to note that this project works best with matched transistors. It is recommended to have at least 25 transistors on hand for matching or to obtain a matched pair from someone else. . All 1/8W components from previous versions have been changed to 1/4W.

The Smoothie has one control:

1. SPEED: This control adjusts the rate of the LFO, allowing you to vary the speed of the phaser effect from slow to fast.
