Guitar Synthesizer Repair Tips

GR-700 pedals work with difficulty or are broken.


What seems to be the problem?

The plastic pedals on the GR-700 tend to break over a period of time. These are unique pedals, sold only by Roland.

The last time I called Roland US, these pedals were not available, but sometimes you can find them for sale on ebay.

Below is a video clip of replacing a GR-700 pedal. All you need is a soldering iron, some solder, and a large, flat tip (standard) screwdriver. First you will remove the twelve 3x15 mm self-tapping screws that hold the side panels on the GR-700, and then remove the 3 4x6 mm screws along the front of the unit. You can now open the GR-700 up. Carefully lift the lid. I placed the unit on the side for my repairs.

You will reheat the solder that holds the wires to the switches with a soldering iron. You may need some fresh solder to help the joint to soften.

After you have the wires off, you need to remove the pedal itself. This is the hardest part. Start with one of the plastic tabs and gently push the tab in. You do not need to push the tab in all the way. While holding the pedal in position with your free hand, do the same with the opposite tab as shown in the video. By alternating between the tabs you can gently work the pedal out. After you remove the existing pedal, the replacement pedal will snap into place. When you press the new pedal in, make certain that the four plastic clips "click" into place. Then resolder the wires and you are done.

Here is a video clip of one pedal replacement:
