The Pros of Treatment

First, it can be a very valid aesthetic decision to treat your drums. With treatment, you can customize the sound, tone, pitch, and decay of your drums to your taste. That said, the drum head affects this decision process no end. A coated Evans G1 sounds very different from a Remo Pinstripe, so each head needs different approaches to Treatment. Refer  to the section on Drum Heads in the FAQ for more information on this. Even if common problems with ringing, decay, overtones, etc. can be addressed by tuning and head selection, Treatment can also give you sounds unavailable with tuning alone.
