pahse 90 mods?

[Phorhas]

hey guys?

what good phase 90 mods are out there?

[Fret Wire]

Standard Block or Script logo, or Dunlop reissue?

With Dunlop re-issues the R28 mod is about the only one I've heard of.  To make it more subtle like the vintage script logo ones, remove the R28 resistor.  

But I liked both sounds and rigged a toggle switch to it.  R28 ON sounds good for slower rates, R28 OFF sounds better for faster settings.

To me, at least.

On the reissues,  removing R28 gets rid of the distorted mid boost. You can change a resistor to get unity gain instead of the volume boost they presently have. You can also remove two caps to mellow it out further, think...Phase 70. Real good for acoustic guitar. When you want more than a phase 45, but a less pronounced effect than a phase 90.
