Yamaha FC5MM Sustain Pedal for Keyboards Right now

To make the sustain pedal Yamaha FC4 work with a Casio wk-1630 keyboard. I bought mine on Saturday just before closing, and needed it to work on Sunday morning. As stated in other reviews, the polarity is opposite for a casio and a yamaha pedal. If in a jam, like I was, and a little handy, here is my soulution: First of all, don't unsolder and switch the wires to the internal switch; it doesn't change the effect at all, so don't waste your time. The actual problem is that the internal switch is an "always-on" switch that is interupted by the pedal action; what you have to do is turn this internal switch into an "always-off" switch that activates or connects the switch by the action of the pedal. Please read all instructions before you begin! This is my fix:
1) remove rubber backing on pedal. 2) remove screw holding switch to pedal. 3) pry contacts gently apart so that the switch contacts don't automaticly contact each other by spring action. 4)Tricky part: gently bend contacts using a needle noze pliar and a steak knife to arch contact while bending tip toward other contact. The finished product should result in contacts close, but not touching, which can be pressed together, but spring apart when let go. 4) Move white plastic cylindrical shaped block from one side of contact to the flip side, using a solder gun to remove and melt to reset. The goal is to make switch fit pedal upside down from it's factory position.
5)Reinsert switch upside down using screw to secure. You may need to loosen mechanical catch on cord to get some slack. 6) Test pedal to see if pedal depresses white block to cause switch to make contact, and adjust if necessary. 7) Replace rubber base and enjoy!Get more detail about Yamaha FC5MM Sustain Pedal for Keyboards.
