RockJAM RJSP01 Professional Sustain Pedal for Digital Pianos and Electronic Keyboards with Polarity Switch

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.

Pedal works well with my Go Piano and assorted synths.Pretty cheap and plasticky but its heavy enough that it doesn't move around too much.Just wanted something that I can sustain notes with and this does that perfectly.I guess if you are keen pianist this might be considered a bit too rough and ready, but for the novice I'm sure its fine.It appears to be the same pedal that can be bought from various sellers from China, but as this is RockJam branded its available to ship direct from Amazon on a next day and only fractionally more expensive. I wouldn't necessarily recommend any RockJam product (they seem to specialise in very cheap 'kids' pianos - the type you would by for child knowing that they'll never actually use it, and if they did take an interest you would probably want something better!) but as the pedal is just a switch not much can go wrong with it :)

This pedal just took my poor playing to a higher level! I’m a hobbyist when it comes to keyboard playing, never had a single lesson, I’ve watched a few tutorials on YouTube and got an idea of chord shapes...I do play guitar so I have the standard guitarist music theory knowledge (minimal) , awkward chord changes have now become a pleasure to attempt and 9 times out of 10 I’m successful! All thanks to this pedal!!Plug and play, easy as that....all you have to remember is to release the pedal as you play your new chord or you’ll sound like a guitarist discovering a delay pedal for the first time.

It is a bit light so I had to tape it down. Other than that it works fine. It has a polarity switch so if its not working make sure to adjust that. I am going to buy a few more for my other keyboards in my home studio.

This didn't work with our piano. It was one of the models it said it supported, but no luck. We tried with the switch in both directions... in one direction it didn't do anything, in the other it was 'sustained' all the time, even when we weren't pressing it. On the upside we sent it back and got a quick refund. Bit the bullet and bought a genuine Yamaha one instead now which works perfectly.
