Going to Home Depot tomorrow to look for something else, maybe rubber grommets or something that will fit around the two nubs and still clear the channel it drops into.
This only fixed the plastic-to-plastic contact that the pedal makes when you push down on it, it won't help the amount of pressure you're using when you press it. A piece of carpet remnant/small mat with a tiny piece of carpet foam underneath might work though.
Trying to think up anything I can so we can play a little later without getting noise complaints. Good thing we don't have downstairs neighbors just yet.
