#1 Phaser

Post by andrew Ivimey »

Back in the day, say 1972, I built a couple of phaser pedals.

Two transistor (stage, notch filters) a foot pedal controlling a dual pot.... it was a good few years later when working for Electro Harmonix that I found that operational transcondomethings did the job but they originally used fets... anyway.... the circuit I'm talking about was almost deffo Practical Electronics, maybe ooooo Elektor or Wireless World.

Yer foot did the whoosh, and what a whoosh it was.

I'd love to find the circuit but I've tried - oh dear -

Anybody out there??? Help

P.s. I've had lots of fun with one transistor, two transistor three potato four fuzz boxes during lock down but handed over to Keeley finally but I'd dearly like to knock up that old phaser.

I remember that circuit (but cant remember it IYSWIM), all the ones I can find are op amp based.

It was similar to this.

Yes something but it used npn transistors.
