If there is a 1/4" sustain connection it should work... there is a polarity switch on the pedal that you may have to flip but that's a good thing. Makes it pretty much universally compatible **Q: We bought the rockjam keyboard rj88dp and purchased the rockjam sustain pedal separate. the sustain pedal does't work. is there a button on keyboard?** A: I have the same type of keyboard I thought it didn’t work as well but it really does you have to know how to use it and the best thing that I can tell you is to go on YouTube and look up a video on how to use the sustain pedal because it is a technique once you learn the technique you’re good to go I hope this helps **Q: Hello guys, i'm looking for a 6-pin din sustain pedal for my piano. do you have any ? thx ;)** A: No **Q: Will this pedal fit a rock jam 561?** A: It did not fit the one I bought as a gift—RockJam 61-Key Electronic Keyboard Piano SuperKit with Stand, Stool, Headphones & Power Supply. Probably won't fit the 561 either, but not sure. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great expression pedal *by C***P on 19 May 2026* Fantastic expression pedal. Ideal for my use. Beautiful and well made. Works perfectly. ### ⭐⭐⭐⭐⭐ Great pedal *by D***S on 30 May 2026* Sustains well and feels great for the price it is ### ⭐⭐⭐⭐ Low cost and does the job. *by B***T on 8 September 2020* This is not a Rowland type quality, but its not a Rowland's type cost either (!) Using it to start/stop an Alesis SR-18 drum machine - and it does the job just fine. No frills just a simple foot switch with switchable normally open/closed switch. You would not want to use this on the road as its not really robust enough and the cable is a trailing one, so if it gets damaged or pulled its a soldering job (lost a star for that), but great for light studio or home use. Would I buy it again - Yes. ## Frequently Bought Together - RockJam Universal Sustain Pedal for Electronic Keyboards and Digital Pianos With Polarity Switch, Anti-Slip Rubber Bottom and 5.9 ft.
