MXR Phase 90 with Script Switch

A few people have requested this so I thought I'd better do it.  This one includes the Script mod on a switch so you can choose either mode.  Don't forget that you really need to match the JFETs for this.  You may get lucky with an unmatched set but the better the match the better the effect, so it's worth a bit of effort.  Use something like a Peak DCA75 if you have one, or this simple build will also allow you to choose the 4 best matches.

Info about the original:
This device has found its way into many of Eddie Van Halen's recordings, adding a shimmery velocity to lead passages or a more dramatic swoosh to muted strumming. Not just for guitars; it works well with bass, keyboards and even vocals. Vary the speed from a subtle, long cycle to a fast, watery warble...and myriad vintage vibrations in between.

[Updated 21st May 2014 - re-jigged to make better use of space but all connections as per the original verified layout]

Modified version with added depth control.  The Depth 1 wire needs to connect in the hole under the link, so it's probably advisable to raise that link slightly to give you room.
