The Master Phaser is a modern take on the 70’s Stage Phaser by Maestro. It features the use of the LM13700 OTA instead of the now-unobtainable CA3094. It also has the option to turn the Phaser into something closer to an Univibe. The controls of the Master Phaser include a Speed knob to set the rate of the phase sweep, a Balls knob to set the amount of feedback, and a Pot2 knob to set the maximum depth of the LFO. The LM13700 OTA allows for the use of either 5 or 6 phase stages, which can be selected through the mode toggle. The Master Phaser is a faithful approach to the original Stage Phaser by Maestro, while also offering some modern updates.
