Project overview
The Master Phaser is a modern approach to the 70’s Stage Phaser by Maestro. Ready to build using OTA LM13700 instead of the unobtainable CA3094.
This board also features the possibility of turning the Phaser into something closer to an Univibe.
Introduction
The Master Phaser is a faithful approach to the original Stage Phaser by Maestro without being strictly a clone.
First, we replace the obsolete CA3094 chips with the most common and Inexpensive LM3700 in its place. Since each LM13700 has two transducers on it, we can choose through the mode toggle to use 5 or 6 phase stages.
Controls
Speed: Sets the rate of the phase sweep from slow to fast.
Balls: Sets the amount of feedback (phase output fed back to phase input).
Pot2: Sets the maximum depth of the LFO.
