Yup, I'm familiar with the R28 mod but I'm not mechanically/electrically inclined. It was easier to find an original pedal.
Also the new Retro-Sonic phaser (www.retro-sonic.com) has the specs of the original Phase 90, is more adjustable, has true bypass, but is impossible to find at this time until they make more of them.
