EX-P Expression Pedal for Keyboards, MIDI Keyboards/Controllers and Supported Guitar Effects Pedals

This pedal has been working great for me! I play a lot of different gigs with it and it's been holding up very well. I love that it has good traction too. My old pedal sometimes would slip while I was playing it on certain floors but I haven't had any issues with this one. The feel is super nice - I'd say it has the same resistance as an acoustic piano. It also is a very quiet pedal which is super important for me since I record a lot of videos on keyboard and don't like it when pedal clicking sounds get through. Very sturdy little pedal and I'm sure it will last a long time!

I bought the M-Audio SP-2 Universal Sustain Pedal for my Casio CTK-2550, and I can say without exaggeration that it completely transformed how my keyboard sounds and feels. This is one of those accessories that doesn’t seem exciting until you use it — and then you realize you were missing half the instrument the entire time. Before this pedal, everything I played sounded flat, clipped, and unnatural no matter how carefully I phrased it. The moment I plugged this in, the difference was immediate and dramatic. Notes finally flowed into each other the way they’re supposed to. Chords had body. Melodies could breathe. Sustain stopped being something you imagined and became something you could control. I tested it right away on “Interstellar” and “Breathe Me” by Sia, and those songs are the perfect stress test for a sustain pedal. Without proper sustain, they completely fall apart — the emotion disappears, the transitions feel abrupt, and the music loses its cinematic quality. With this pedal, those same passages suddenly worked. The crescendos landed, the decays felt intentional, and the songs finally sounded the way they’re meant to be played. It genuinely makes or breaks them. One of the most important reasons this pedal works so well — and something I don’t think people talk about enough — is the polarity switch. This is a must-have feature, especially for Casio keyboards like the CTK-2550. Different keyboards interpret sustain pedals differently, and without a polarity switch, you can end up with a pedal that works backwards — meaning notes sustain when your foot is off the pedal and cut out when you press it. That’s not just annoying; it’s completely unusable and will drive you insane. The SP-2 has a polarity switch, which means it works correctly and immediately with the Casio once set properly. No guessing, no weird behavior, no troubleshooting for hours. One quick switch and you’re good. Build quality is another major reason this pedal stands out. It feels like a real piano pedal, not a cheap button pretending to be one. The pedal has weight to it, a smooth piano-style action, and a solid resistance underfoot. It doesn’t feel mushy or clicky — it feels controlled and expressive, which actually matters when you’re trying to play dynamically. The rubberized bottom is also a big plus. It stays put on the floor instead of sliding away mid-song, even during heavier footwork. That stability makes a difference when you’re focused on playing and not thinking about chasing a pedal across the room. A few practical notes that helped ensure everything worked perfectly: • Make sure your keyboard is turned off before plugging the pedal into the sustain jack. • Plug the pedal in first, then turn the keyboard on — this helps the Casio detect the pedal correctly. • Flip the polarity switch if sustain behavior feels reversed. Once set up, it’s completely seamless. Yes, it costs more than the ultra-cheap pedals, but this is one of those cases where the difference is absolutely justified. This feels like a long-term piece of gear, not a disposable accessory. If you care at all about expressiveness, phrasing, or recreating emotionally driven pieces, this is not optional — it’s essential. Bottom line: if you’re playing a digital keyboard and want your music to sound full, connected, and emotionally convincing, the M-Audio SP-2 is worth every dollar. I wouldn’t play without it now.

I bought this sustain pedal along with the Williams Legato 88 Key-Keyboard and I am so happy with it! Most importantly it works extremely well! Sometimes, when playing piano, I may adjust my seating and when the time comes to press the sustain pedal I have moved slightly out of position to press it down fully. But the pedal picks up the signal and it sets the sustain just as I would expect from a real piano. The reason I am mentioning this is because I do know of some plastic sustain pedals for keyboards that DO NOT set the sustain unless you press that pedal all the way to the base and I do not like that. This can get you in a bad habit of "stomping" the sustain pedal which will lead to damaging the pedal and it creates a subtle but none the less audible "thud" in grand pianos. However, this pedal is forgiving and it never get's stuck in a pressed position (again, like some plastic pedals I know of) The pedal has a rubber grip that covers the whole underside to prevent from sliding and it has weight to it which is really important. When I press down on the pedal it always remains stationary and the feel/resistance from the pedal is spot on with that of a baby grand piano (which Is what I play on when I'm at my mother's home - I grew up with the instrument.) Underneath the pedal (on the base, not the pedal) there is a raised rubber stopper which prevents the pedal from every touching the plastic base. This is fantastic because you will never hear "tap" sound when pressing the pedal down all the way. It also doesn't have noisy springs inside which make a subtle crackling/popping sound when compressing and expanding. I have heard these affects on other plastic sustain pedals. This pedal is excellent quality. Not only does it feel right, it also looks fantastic. The sturdy plastic case is a nice solid black and the chrome pedal itself is just gorgeous! It is a smooth round shape at the end which I prefer - it looks really nice. It comes with a small plastic cover for the chrome portion (doesn't cover the whole thing, just the majority). It is a sturdy cover, not just a cheap and flimsy one to keep it safe during shipping, it is part of the product. It fits snugly when attached, doesn't slide and is easy to remove. I have decided to keep it on just too keep the chrome shiny for as long as possible. It is a pedal to be proud of. The cable is long (~6ft), perhaps longer that necessary for any setup I can think of but regardless; I would much rather prefer too long than too short when it comes to cables. I am sure anyone else would obviously agree. The plug is the standard 1/4 inch and it too is well made. It isn't flimsy. The only issue I experience (know before reading the rest that it may not be an issue with the pedal) is having the sustain pedal invert when I turn on the piano. This means that pedal will set it's sustain while unpressed and shut of the sustain when pressed. This only happens rarely which is strange - might happen from pressing down the pedal while powering on the keyboard but I'm not sure. Either way, It really doesn't bother me so much. If this issue occurs for you it is easily fixed by powering off the keyboard, removing the plug, putting it back in and turning the keyboard back on. However, I can't say it is even the pedal's fault because it could just as easily be the keyboard's fault (which I think is more likely and makes more sense). I just thought this would be fair to mention just in case it is the pedal. To sum it up - I can't see any other pedal performing better, feeling better or looking better than this pedal at this price or even more! It is an excellent choice! I recommend it.

I like having the adjustment knob which allows me to set the silent point of the travel at the physical stop. The adjustment is a bit sensitive, and slightly difficult to set exactly. Also, there is a tiny bit of free play in the pedal linkage, which makes precision a bit less than I would like. The mechanism, a slotted lever and round pin, is very standard for foot pedals, and I am being overly picky about that. I am comparing this to a Studiologic VP-27, which I have nearly worn out. The VP-27 uses a nylon rack and pinion gear system, which is slightly more precise. Overall, this is a very good expression pedal, which should work well for nearly any expression pedal application using a TRS plug.

I really like this Universal Sustain Pedal. It has a nice, piano-style feel, responds smoothly, and works well with my digital piano. The build quality overall is solid. However, the grip on the bottom definitely needs improvement. It’s always slippery on my carpet, and I have to stop frequently to reposition it. Better traction would make a huge difference. Overall, it’s a good pedal with great functionality, but the lack of stability on carpet holds it back.

Good product

Bestellt am 18. Mai 2023 für €15,00. Klein, günstig und robust. Ich steuer damit Start/Stop vom meinem PSR-SX900 Keyboard. Klappt prima. Gut ist der Polaritätsschalter. Denn nicht jedes Device ist da gleich geschaltet.

Estoy muy satisfecho con el M-Audio SP-2. Tiene un tacto muy parecido al de un piano real, lo que hace que tocar sea mucho más natural y cómodo. Funciona perfectamente con mi teclado y la respuesta es rápida y precisa, sin retrasos. El pedal es resistente y estable, no se mueve mientras lo uso, y el cable es suficientemente largo para colocarlo cómodamente. Además, su diseño simple y clásico encaja bien con cualquier setup de teclado o piano digital. En general, un accesorio práctico, confiable y de excelente calidad. Ideal para estudiantes, músicos en casa o en el estudio. ¡Muy recomendable!
