I've been away from drums for awhile. I have a set of Pearl forum series from a pawn shop but brand new. I replaced batter heads with Evans wet heads(hydraulic glass). This was a mistake I do believe. The tones are not right for me. It seems to kill the resonance. After playing them I am thinking maybe coated single ply batters and maybe even coated resonants. I know the quality of the drums I have so any advice will be appreciated.
