That includes replacing the old school felt washers on your cymbal stands with the latest technology. I have replaced all the felt washers on all my cymbal and hi-hat stands with Cympads. I can't tell if they have improved or even changed the cymbal sounds. But I like their consistent density and the assortment of sizes and colors. Highly recommended for the drummer who has everything or demands only the very best.
I am not sure these foam pads will last as long as felt does, but they are cleanly made, good fits, and do the job. Remains to be seen if they will disintegrate over time like most foam does, since I only have been using them for 2 weeks...
