Nice for deep, thocky sound
Really easy to install, cut out precisely, make for a noticeably deeper thocky sound (on my kbd67 lite r3 w/ Gat Milky Yellow KS-3 Pros), maybe a little too deep and thocky. I believe PE foam would yield more of a marbly sound, so i may go that route later, but these are great for quiet, deep, thocky builds. Can be peeled up if lightly applied crooked. Press down after ensuring the pad is centered to stick it down. Apply with tweezers.
An underrated mod
These are easily applied, and I experienced no difficulty putting the switches in after applying these. They definitely refine and clean up the sound of the keyboard, I interpret it as creating a bit of a quieter, poppyer sound.
These pads are the most amazing lowkey mod you can do to your board. I've improved the sound and even feel of $500+ boards with these things and I will never build another without them. I personally prefer these to PE foam as they give a more "solid" sound while the PE foam sounds more "thin" to me, if that makes sense.
Excellent, cheap, time consuming to apply though
Application was fairly easy, and they did seem to change the sound of my board. Feels similar to the PE foam mod almost, but without any risk of damage to the PCB. Good stuff. May take a while to put them all on.
Made my keyboard sound much better. I'm searching for that perfect sound, and these switch pads put me on the right path.
