About This Listing

From Modest Mike's Mods  BBB A+ Rating
All of our modified pedals are warrantied as new!
Modified MXR Phase 90 - Script Mod plus Univibe Mod!
Switch gives you the option to use it as a phase shifter or univibe!
Our script mod improves the sound of this pedal by helping to eliminate the noticeable mid-boost distortion. This pedal is now warmer, more like the now very expensive version of the one made back in the mid 70’s when I used to play (Yep, I’m getting old). I am referring to the original version that practically defined the classic phase shifter sound, and was heard on everything from hard rock to jazz fusion to funk hits.
We also replace the LED with a bright water/clear blue LED. The LED is clear when off, and a very noticeable blue when the effect is on.

Some folks offer the Univibe Mod.  But that's a permanent mod which does not allow you to use the pedal as a phase shifter.
None of them offer you the option to make the Univibe Mod optional by installing a 4PDT toggle switch. That's right, I said a 4PDT toggle switch. A true Univibe mod involves changing out 4 capacitors for all 4 stages of the pedal with 4 caps of a different value.
With the 4PDT installed, you now have the option of phase shifter or Univbe!  That's a total of 8 capacitors and 8 wires being controlled by a simple flick of the switch (see picture #3).
This switch is installed in the battery compartment of the pedal. You will need to use a standard center negative power jack to use this pedal.

"Mike the pedal is amazing! I hope you're going to keep doing this mod because I may have to buy this for 2 of my friends birthdays in the fall."
