Title: 6 stage optical phaser project
Post by: jubal81 on July 14, 2012, 07:50:46 AM

I was surfing around and came across the sweetest phaser sound I've heard. The project is pretty well documented, but it's broken up over three pages and the author isn't a native English speaker, which makes it pretty confusing since I don't know much of anything about phasers to begin with.

Here's the link to the first page:

Here's a link to the demo:

What I like best about this is that it looks like you don't need LM13600 (aka awful to find from an e-tailer that is NOT ebay) or matched FETs (aka have fun with the bagful of FETs that don't match up!)
