To spare myself time and the money required trying out bass drum heads, I thought I would ask a few quesions on here about bass drum heads and muffling. I am in need of some new heads, both resonant and batter. First of all, I have only used Remo PS3 heads. I was thinking about a PS4, but does the extra ply really make that much of a difference? As of the moment I am using two Large Towels as internal muffling along with a Remo PS3 reso (ported) and batter. I was thinking of making the move to using a different style of muffling using foam rings as in the Remo Powersonic, and Evans EMAD, and eliminate the towels altogether, as it looks better, and it eliminates me having to re-adjust the towels every time after moving my drums from gig to gig. My next question is, will the Powersonic or EMAD heads get me the same feel and sound as using the towels? I once heard that they are two different types of muffling that will give two different kinds of sounds. Is that true, or can you achieve the same sound with both types of muffling? Thanks!
