Wanted to share a mod I did on my EP-1r (as far as i understand just using a mono-jack won't work because the tip will be grounded in either end og the potmeter?) The EP-1R is wired as a traditional expression pedal, and it has a switch for reversing the polarity. I wanted to use this pedal on my Helix and thought I could use this switch to switch between Line6-wiring and "normal" wiring. The reverse functionality/polarity switching I think mostly can be solved in the setting - at least it is possible on the Helix. Well, I ended up with wiring up this modification. Just tried it on a Helix, but works perfectly in that mode. Probably will try it on my keyboard. Does anyon see any flaws in my wiring?

Hi I just did this rotary encoder replacement, and I took a few pictures of the process. Took me a couple of hours. Thanks to Haight Asbury Music who bothered to send a couple of these encoders all the way to Norway. Regards Espen The broken switch New replacement switch Back panel off. Beware of the placement of the steel-part vertically in the middle and make sure this is in place before closing the unit when done. The area where the encoder is mounted on the pcb. Remove the "nuts" from the jack plugs. Beware that the plastic washers are REALLY fragile. A couple of them just broke to pieces by staring on them. The wires to the exp.pedal. The glue must be cut/removed The wires to the pedal switches. Remove the screws from the XLR-sockets. AND this little torx/hex screw Remove the torx/hex screws for the display/rotary panel. It's probably smart to remove the knobs as well to make the disassembly easier. So far so good and about time to switch on the soldering iron. Remove the plastic "switches". They have "clips" on each side through the pcb The good encoder, the bad and ugly encoder. A couple of pics of how the encoder is soldered The area with the encoder desoldered and cleaned up. The new encoder soldered in place... ...and working
