Maestro PS-1A Phaser

Here’s a continuation on the Six stage phaser post.

So I finally got the fets matched and ready to go into the circuit. It all seems to work as it should. Here’s a short soundclip recorded as I take it through the presets, slow, medium, fast and then back to medium and slow. Poor quality on the recording though, using a tone generator and cellphone for recording.

You can hear the nice feature of the ramp working.

Now the work continous, it’s time to modify. The input buffer needs some tweaking and the I’ll have to decide how to the speed presets will be set, who knows were it will end.
