It does not apply to the EVH phaser, Custom Shop Script models (with and without LED), as they have a different type of circuit board. The 1974 Handwired model can be true bypassed with the help of this post. But for this excercise, make sure the circuit board in your.

The 1974 Handwired model can be true bypassed with the help of this post. But for this excercise, make sure the circuit board in your. Not sure why anyone would waste time trying to draw a schematic. It's a '74 Phase 90. I'm sure everyone has an official MXR vintage script Phase 90 schematic! I'll attach my original 1977 schematic. If I only had 5 postings. Icarefone serial key 2021. Lol Everything is as close to 1974 as RoHs will allow. If you find any discrepancies blame RoHs. Spc 600 nc driver. Great sounding phaser!! I've never heard how the original MXR phase 90 sounds like but, this circuit works for me. At first I used unmatchet 2N5457 for jfets. I've been changing severel (it was easy because I used sockets for them) untill I got the right sound (tweaking the trimer is very imortant too).

The MXR Phase 90, probably the most popular Phaser Pedal (especially since Eddie Van Halen used it). The Phase 90 is a JFET base Phaser circuit.
It uses 4 JFETs which needs to be matched to get proper phasing. For my build ive used a Madbean NomNom PCB and a matched JFET Quartett from Musikding (2n5952)
You mach the JFETS by yourself too. Instructions for this are in the Madbean NomNom build doc. Phase

All parts except the JFETs are very easy to obtain. Vintage mxr phase 90 schematic

For my build ive used following mods, which are the original does not have:

Rate LED (which is also used as bypass LED)
Feedback switch (intesifies phasing, when on)
