Hi guys,

I just got one of these for repair. An opamp was blown, so I replaced it, and took some pictures. It's a great sounding box with very interesting features, not unlike the classic Roland Phase Five (which I also have, if there is any interest), but more tonal options are available from this effect.

I've uploaded some pictures on my website:

It would be awesome if someone wants to trace the schematic, as I have a lot of examns right now. If there's an angle I've missed, drop a message and I'll snap a picture. Also if the 3PDT's can't be read by the picture, I'll help you out with that.

Hey again,

No, the Tom Clancy-potential is not that big - I just messed up the extention's case on the last pictures. Fixed now! :oops:

Hey Boris,

Did you get a chance to take a look at it? If so, have you come up with anything?

well out of my league for tracing, but would love to see if anyone with some mad skills manages to get it cloned 8)

Hey Boris,

No worries. I'll write in here when I'm gonna start tracing it myself - we can both work on it, for added redundancy of the finished schematic.

@Rocklander: I'm gonna make a clone of it, as it really sounds good and is a very musical piece of gear. So all things fair, I've ordered one myself. Thanks for the comment!

This one is definitely beyond my tracing skills, but I would love to see a project from this. :thumbsup

I haven't thought about this for a while. I was hoping someone was up for the challenge, as I haven't had a spare moment the past 10 months. It's a really nice sounding phaser, with some cool features. Definitely a cool thing by Mr. Pigtronix.

Someone I've been repairing some old EHX stuff for is supposed to send me one of these to work on as well... so, maybe soon I'll have something to add to the discussion. 8)

I haven't received the Pigtronix phaser, but I did recently repair/mod an E-H PolyPhase envelope phaser, if anyone's interested in that.
