Maybe I should be clearer:

By phase shift oscillator, are you saying phaser?

I’ve never built a phaser, but I don’t think it would be that difficult. They’re rather simple. Usually just an oscillator with a bunch of allpass filter stages and a feedback circuit.

do you have the part list for this schematic? im sure i got them all layin around, ill whip one together real quick and let you know!!

You can make an oscillator with a 555 timer IC.

There a are a couple simple oscillators here:

Okay, now I have to ask *you* a few questions:

Where are you curious about whether someone else has built one? Do you have questions about its use?

Do you have an application for it, and therefore are thinking of building it?

Do you have any idea what it’s normally used for, or is this similar to someone who reads about a device, and decides it would be good to have one, even if that person isn’t clear what it does?

Given the following comment…

…it seems that you’re not familar with basic effects or ciruitry. That’s okay, since everyone has to start somewhere. However, one does have to *start* somewhere.

Given what you’ve linked to, you might consider building a tremolo unit. There are kits for such pedals, so you’ll gain a bit of understanding, and can then decide if you want to go further.

Of course, if it’s just idle curiosity, and you don’t want to do the research yourself… then at least spell out what you want, so others can decide if they want to invest their own time to make up for time you don’t want to waste on your own question.
