DP6 polarity switch addon

Pedal polarity conversion guide Have you ever had to play on an unknown synth, just to find out that its sustain polarity doesn`t match your pedal? Some synths, like the triton, have software switchable polarity, but it can often be hard to find on an unknown synth. Roland have one of the best (in my opinion) sustainpedals, called DP-6. It is durable, has a "lip" that goes under your heel to prevent it from sliding on a slippery surface, and it comes quite cheap. It is even available in at least two colors (black and brown). This guide will let you modify this pedal to let you select its polarity with a switch located in front.

What you need: a Roland dp6 (of course), a switch, two short cables, a philips screwdriver, a drill and a soldering iron.

Turns out the dp6 pcb have a unused point called "dp5". Guess they have an alternate version with opposite polarity. What you do is simply having the switch select between the dp6 point and the dp5 point.

Picture: The yellow, thick wire remains where it was. The wire with transparent isolation is originally soldered at the "DP-6" point, located bottom left at the picture. It must be soldered to the common (centre) point of the switch. The red wire goes from "DP-6" to one free switch connector, and the black from "DP-5" (top left) to the last free connector.

Open the pedal. Drill a hole suitable for the switch (remember to make space for the pedal moving up and down). Remove the cable going to the "dp6" point, and solder it to the common (centre) point of the switch. Solder a wire from "dp6" to one free switch connector, and another from "dp5" to the last free switch connector. Mount the switch in the hole, and mount the pedal. That`s it.
