Chromatics is Cympads' modern take on cymbal felts for your cymbal stands. The felts are actually made of a foam material that works really well for your cymbal stands.
Not only do they look better, but they also last much longer than traditional felts. Additionally, they provide better movement for your cymbals, resulting in a better and more open sound in your cymbals.
The colored foam discs are 15mm thick and come in packs of 5 each.
You are meant to use them over your cymbal, with Cympads Optimizers underneath your cymbal.
The black optimizers are made of a slightly softer foam and come in 15mm, 12mm, or 8mm - depending on your needs.
You should therefore check how much space your cymbal stand has under the nut, and choose a thickness of felt to place under the cymbal that makes sense in the overall "height calculation" (your Chromatics felt is 15mm over the cymbal).
White, Red, Green, Blue, Yellow, Purple, Orange, Pink, Crimson, and Camouflage.
Chromatics are made of a different and slightly harder material than Cympads Optimizers, which is why they work best on top of the cymbal.
