Damper pedal no loner works. Could it be just a loose wire? screws on bottom have been lost.

Lots of advice on this page.

Try plugging in the pedal with the Roland powered down or off. With the pedal plugged in, turn the Roland on again. The Roland should sense the polarity upon power up. If this doesn't work, I have had those pedals get defective right out of the box, so try this...Get a ¼ inch guitar or signal cable and plug that into the damper jack. The cable will represent an open circuit polarity since nothing is shorting out the leads. See if the EP77 is sustaining or if it is not. Alternately, try shorting the guitar cable by laying a piece of metal across the top and bottom of the jack. A pocket or kitchen knife or any bare wire will do. If this does not work, your assumption about the power supply may be correct.

I can't! In my opinion, no. Start drift boss customize your car by choosing different colors and patterns.

First thing is to check the connector is fully seated... sometimes most of the contacts make but one might not. Beyond that, contacts in the pedal are next suspect.

Hi genoness1,

If you noticed that the pedal works on and off depending on the jack plug positioning, it is because the jack is already broken loose from the solder on the board. If the pedal that you are using can normally open as most or normally closed like Roland types, you can still replace the loosed jack. Unit has to be opened and correct jack replaced.

Hope it helps.

Thank you for using FixYa.

Please note that ROLAND equipment USUALLY uses Normally closed (electrically) damper pedals for their equipment. Most other brands use normally open ones. If you are using a non-Roland pedal, that is likely the problem.

SOME PEDALS require opening and changing a wire (involves soldering) to match the unit you are plugging into. A very few have a switch on them to allow changing polarity.

A few synths, like the Yamaha Tyros have a built in setup screen where one can select the polarity of the attached pedals.

For a damaged cord, just buy a cord wot correct plugs on it and open pedal and replace the cord. There are usually only two wires to worry about.

I had the same problem, its to do with the polarity of the pedal. My pedal had a polarity switch on the bottom just flick this over and this should fix the problem. Otherwise another solution was to hold the pedal down and turn the keyboard on.

There are two types of damper pedal switches, on that is closed until you press it, and one that closes when your press it. It sounds like your Casio is expecting one type and your Roland pedal is the other type. A quick way to test this is to plug a guitar cable into the Casio pedal input and see if the keyboard sustains. If it does, then your Casio requires an "normally closed" switch.

Some pedals have a small switch near the cord or even on the bottom of the pedal that will reverse the switching operation (BOSS pedals, a division of Roland, have this feature). If you can find that, then change the switch position and you should be OK.

If not, and you feel like digging into your pedal, you could take the bottom off of the pedal and check out the switch itself. Many pedals use a switch that can be used either way. The clue will be on the switch itself. If there is an extra tab on the switch that is unused, then switch the wire that is furthest away from that tab to that tab. This will probably involve soldering, but it is nearly impossible to damage anything.
If moving the wire that is furthest away does not do anything, then try putting that wire back and switching the other one.

If your pedal does NOT have an extra tab, you're SOL, unless you want to buy a replacement switch (unsure of make). If this is the case, you are probably better off getting a different damper pedal - preferably one that is marketed as "universal"

I'm 90% sure the pedal is shot ... It could be the switch ... Open the thing up (If your confident) and look to see if a wire has come loose ... If no wires are loose then try another working pedal with the keyboard.

If it still won't damp then there is a problem with your keyboard and I do not suggest opening up one of those ... I used to repair sockets and keys on those for a local boys school and there are full of things that can break if not opened properly,

My suggestion is getting someone in to repair the keyboard if its that ... If its the pedal then either get a new one if you don't want the old one repaired ... Or repair it yourself (pretty easy if its the wiring ... fiddly if its the switch but only attempt if your confident and have the proper tools).
