    How or what is the best way to adjust the trim pot in side the Phase 90 reissue's. I saw somebody talkin about this in the one of the topics. If anyone knows anything about this i'd really appreciate it.

    There is a trimpot towards the top of the circuit board (North of the speed control) that can be adjusted with a small allen/hex wrench. If you pull off the back of the Phase 90, it's the hole covered with the little blob of goop. Pop off the goop and have at it. I found that mine was pretty much already where the "sweet spot" is to my ears...

    There are other mods, too. I have read that supposedly removing R28 (a resister on the circuit board) gets the box closer to vintage Phase 90 specs, and removing R11 and R12 was recommended as well. I tried removing all of the above...it definitely made the pedal more subtle and it doesn't boost/distort quite so much anymore. I will probably put R28 back, because I like a more drastic phase effect...

    Oh, and it's a bummer, but the parts on the board are marked underneath the parts! So you pretty much have to remove a part to know which one it is!...

    OK, read ratter's post and imagine it said with Doc's voice from Back To The Future.

    LMAO!

    Hah! You shoulda seen me actually working on the thing...I removed EVERY resistor to see which was which! It was definitely a Doc moment. And I'm not too proud to say that I think I liked it better before ...I might put everything back to stock.
