    Default Phase 90 R28 Mod with toggle

    I picked up Phase 90 for a good price but didn't like the sound as is. I had read about mods and it seemed the R28 mod was a good one to make to get closer to evh. However, I wanted to be able to return to stock sound if necessary with toggle, not just cut it. If you have soldering skills this modification should not be to challenging. I don't like to work with an iron, but seemed to work the best as it was tight. Attached are some pics from my modification. I did remove capacitor entirely by heating the solder and pushing it out with the tip of the solder iron. Gets very hot, be careful. Then, soldered the bits together as shown, then added a bit of tape. The toggle is from the source and fits through 3/16 hole. Definitely, sounds better now.

    This kind person posted a good guide to follow that includes other mods http://www.erikhansen.net/p/pedal-mods_23.html.

    Am I right in thinking that this mod mixes the phased and the dry sound 50/50 and the toggle is like the script/ block button on the evh model?
    I used to be 'sean112' but lost all my details!

    Not sure if it ends up being 50/50, but does improve the sound. The R28 modification does seem to get you closer to the sound of the script by eliminating the distorted mid boast.

    This guy does very nice review of the original and script where you can hear the differences. That the script sounds more subtle for sure

    He also does one with the EVH model and script. I like the script over the evh version and regular block

    The R28 mod is the easiest, most effective mod in all of electronics!
    Snip. Done.
    IMO, adding the toggle is a waste of time as the stock sound of the pedal is not very good.

    I bought the block logo a couple years ago and didn't like it at all. Returned it then later got the EVH. Was very happy with it until I plugged the wrong adapter in and fried it. I have the script now and love it. Such a great pedal.
