this is a Pearl Tru Trac 14"
(I painted it Black with rubber paint to enhance the rebound, since its rubber paint you can remove it in one go without leaving any damage or residue)
on one side you have the Pearl tru trac, on the other side a 3ply mesh head in case you want to connect both and let your creativity flow, yes, you can add a second 2 zone system on the bottom if you know how
