Introduction: Repair Your Footswitches (SPDT, DPDT, 3PDT)
After a while some of them came with footswitch problems. You had to click the footswitch several times before the sound came through completely. If not, it sounded like you turned the volume down, so the signal was very weak. This happened in both way, with the FX on and the FX off. Annoying!
You can do two things: Buy high quality footswitches (can be very expensive!) instead of these economical footswitches, OR fix it yourself! I fixed like 10 switches, and 8 of them did work again after using this method (And they still do!)
You will need the following tools:
- Screwdriver (Flat and star)
Step 1: Isolate the Footswitch From the FX
Remove the screws from the backplate. Then create a picture of the current wiring, it's a lot easier if you put the switch back later. Remove the nut from the footswitch on the front of the FX. The switch will come loose. Remove all wires by desoldering them.
I left the red wire in place because It doesn't go anywhere.
Step 2: Break the Switch Open
The switch is held together by 4 clamps on its body. Bend all clamps a bit up by using a flet screwdriver. If you only bend one side, you'll get problems putting it back together. Carefully open it and put the parts away.
Step 3: Cleaning
Clean the metal plates and put them back in on their place. Use a pincet to do this the fastest way.
Step 4: Filling Up the 'pushers'
I believe the switch won't work proberbly after a while because the metale plates make bad contact. To make sure they will, you need to fill up the holes behind the pushers.
You can use some paper to fill it up, but make sure they lay flat by pushing it with a stick that will fit in. After you filled the holes, gently put the pushers back in place.
Be carefull! If you use to much paper, the footswitch won't work anymore. Find out yourself howmuch you'll need.
Step 5: Put It Back Together
This might be a tricky step, but it'll work. First put the pusher back on it's place. If you you can simulate the clicks by moving it up and down, it'll work. If not, you have put too much to fill the space of the pusher.
Put the white plastic pin and the spring back on its place (Picture 2 and 3). Then gently put both sides together and bend the clamps back on their place with a clip.
Then install the switch back on it's place (Step 1 reversed), but do not tight the nut; give it a test run first.
Step 6: After the Repair
If it doesn't work, try again. If the switch doesn't click at all, you proberbly have used too much paper for filling up the holes, or the metal plates are out of their place.
