This Digital Keyboard does not come with a pedal unit. • You can use the PEDAL1 jack to connect an optional (SP-3, SP-20) sustain pedal. You can use the.

I would suspect the sustain pedal jack on the keyboard is either dirty or defective. Try using some contact cleaner first, and if that doesn't work replace the jack.

When you replaced it, you either have the wrong jack, wired it wrong or it is shorted out where you connected it. Recheck the connections.

DId you remove the plug from the input jack to turn the pedal off? If so then you may have a bad input jack.

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.

The first thing i would check is the ac adapter .Make sure you are getting the correct voltage from the adapter.If you know how to use a voltmeter or know someone that has a volt meter,check it with it unplugged from the guitar pedal,most of these have a voltage range from 9 to 12 volts dc.you could also take it to your local radio shack or local repair shop and they will be glad to check it for you for free.after you confirm the adapter and it is ok then the next thing you will check is the input jack assy on the pedal,input jack assy are soldered onto the board at the factory,these jacks ,no matter what it is are famous for cracked solder joints where the pins of the jack go into the board because of stress delivered to it during plug ins and plug outs.if you dont know how to use a sldering gun or dont want to you will have to take it it to your local repair shop-cost should be around 15.00, 20.00 tops,make sure that your guitar cables are good,check the 9volt battery inside the unit if it takes one,if its dead that could be your problem,if all above fails i would send it back to the factory or wherever you bought it.,good luck been playing for about 30 years myself,rock on

You might have to replace the input jack for your pedal. It will involve disassembling the keyboard enough to get at the solder side of the circuit board where the jack is mounted. Desolder the jack and take it to a good electronics parts supplier to obtain an exact replacement and solder the replacement in. That is the easiest fix.

The probable problem is poor connections at the input and/or audio output jacks.

Usually the power supply will fail either on or off which is sometimes cause by a bad input power jack.

In any case, the problem is likely internal and will require repair.

The fact that the pedal works in the on /ff is not a complete exhoneration.

Due to certain possible failures the pedal can still be at fault. Test the resistance of the switch and leakage resistance.

The two inputs may have different electrical characteristics where one would tolerate a partially defective switch and the other would not.

Use an ohmmeter to test the pedal before drawing conclusion.

If you only replaced the jacks, then check where you soldered your wires. The ground wire from the circuit board an/or switch will be wired to the sleeve of the jack. The tip of the jack would be wired to the output lug of the switch. Also check the wiring on your in jack to make sure the correct wire is going directly to the switch from the jack's tip. The ground wire will go from the sleeve to the circuit board and/or ground lug on the switch.
