My reissue MXR Phase 90 now rocks, big time!

I know we talked about this at the forums, here, there and everywhere, but I'd like to share the fact that modifying your reissue MXR Phase 90 really works.

I bought mine a few months back and wasn't impressed at all with its effect. I just couldn't feel it. It wasn't doing anything that ressembled EVH's famous phasing sound.

I was told to open the back, pop the silicone plug at the top of the circuit board and start panning the hidden pot with a small Allen wrench until I found the sweet spot.
I did just that, but couldn't find the spot. I guess I was moving the pot too fast past the perfect position and gave up.

Last night I decided to take time and try again. This time around I moved the pot from full left to full right in very small increments (1/2 hour increments on a clock). After a while, that famous, early VH effect sound litterally knocked me down off my stool!

I mentally noted the position of my Allen wrench and kept moving further to the right to see if it could get better, but realized it was fading away rather quickly.
I reverted to the magic position and closed the back.

I can't wait to go and use it next time I record something!

I want to do that mod on my Phase 90 reissue as well. I have a 1980 script phase but I think it is a lot noisier
and sucks more tone when off.
So, did you clip that R28 resistor? If so, which one was it. I remember a website that showed where it was but now that site is gone. [img]images/smilies/icon_mad.gif[/img] Well anyway, I can't wait to do mine. Just wanted to know about that R28 thing. [img]images/smilies/icon_thumb.gif[/img]

I burnt my reissue one out and am using a Line6 at the moment (less noise as well!) but I will definitely try what you've suggested cos I thought the same thing...it wasn't doing much or it was doing TOO much! [img]images/smilies/icon_doh.gif[/img]

There is a very fine line between the position where the sound phases the way we want, dies flat or goes overboard. The range is very small. Take your time.

Note: while adjusting the pot, I didn't even play the guitar. I had the amp on a pretty high gain and volume setting and just listened to the way the hisss sounded.

As per the the R28 thingy, I didn't touch anything. It works the way I want this way and isn't very noisy.

I recall the Web site you're refering to I just checked and it's gone; you were right. That's a bitch because I think there was a diagram showing you where to clip the diode.

Do this mod, it takes 5 minutes and after that you'll want that phase on 90 percent of the time. The phaser also works well with clean amp settings at times; check it out...
