There´s a sucker born every minute - and too many of them end up in the bootweak pedal biz.

from what i can see, it looks like it could be very similar to the phaser side of the jet phaser. I fixed one a few years ago for a friend. Even offered to buy it for $50... He laughed at me :)

I seem to remember two LM324's with 4 jfets inbetween... looks like a similar layout from what i remember, at least in that particular section of the PCB.

It´s a 6-stage Fet-based Phaser

ahh, yes, now that i look a bit closer i can see what appears could be two more fets over on the left side of the board.

I've had the pleasure of playing around with a jet phaser, and the AP5, which was pretty cool as well. Never tried this one, or even seen one in real life.
The AP 5 was probably the coolest phaser i've ever tried. I've tried to get one since I heard it years ago.

Unfortunately i missed this acution last week

it also has a gut shot.:)

I took some shots if the PCB when I repaired one last time. I'll try to upload those, as well as what I have from the Roland Phase Five, if anybody is interessed? I also have a Ibanez PT-999 which is a Phase90 from Ibanez, if anybody wants to see that.

Yo

I currently have one of these that a friend of mine said wasn't working right. Someone replaced the output jack. It seems to phase ok but distorts in an unpleasant way when the strings are hit harder. Anyone seen a schematic around for it? The Roland phase-II ap-2 that is...

Hi there. I am afraid the link is not working, and I really need this to fix my recently non-functional AP-2 pedal. Could you please repost the link? Thanks.
