Casio SP-34 Sustain Pedal Unit

If you care enough about the playability of your instrument to get one of the Privias compatible with this pedal, the upgrade is a no-brainer. Even if you only use the far right pedal, it's a huge upgrade in feel from the tacky footswitch-style sustain pedal included with the Privias.

Really solid base which stays in place without needing any additional non-slip measures, nice weighty pedals with smooth action. The only criticism I have is that the sensitivity doesn't live up to the otherwise impeccable accuracy of the rest of the Privia experience. I'm by no means an advanced player but it felt like it lacked the nuance of real pedals where you get different effects by pressing down at different weights. I'm not sure if this is a shortcoming of the pedal or the PX-S1000 itself, but either way it's a noticeable flaw.

Even with that caveat, it's an easy two-thumbs-up recommendation from me.

I bought this as part of a bundle, with the Casio PX-S1000.

Overall, the unit looks simple and elegant.

The rubber feet ensure there are no problems with slipping at all.

The pedals all feel nice to use and are very responsive.

The damper pedals work very nicely and they do respond to different levels of pressure - it's not just on off. The range is quite small so it does take a little bit of control to keep constant if you don't want it fully on. The right-hand pedal makes a slight whirring sound when pressed in which is audible over headphones and can be a little off-putting.

The soft pedal is fine for brighter tones but if you're already using a fairly dull tone (e.g. the default tone on the Casio PX-S1000) then the effect is barely noticeable at times.
