How To Do ADA Flanger "Paul Gilbert Mod"

I have performed this mod for a few people. It is really shockingly simple to do. This seems to work much better on the original units, but should also work on the re-issue units. In my experience, the re-issue units won't go quite as crazy with the runaway oscillation but will still do it. Below is how to do it.

After completely dismantling the unit so you can get access to the trimpots, you are now ready to find the one trimpot that needs to be adjusted.

The trimpot inside the yellow circle near the "Enhance" pot is the one that you'll want to adjust. This basically controls how much effect the "Enhance" pot has, and is intended to limit how far it goes. You'll just simply adjust it until you get the desired affect on the sound. To do this you have to play your guitar thru it while it's all apart and fiddle with the "Enhance" control until you're happy with it, being careful not to shock yourself or short out anything on the PCB. OK, now you're done.

Yes, that's all there is to it! All that is left to do now is to put it all back together and enjoy the fruits of your labor.
