...and I hate the paying for a new one part about changing heads even more. So I say: when you wear through it with your beater. Plus, it sounds like you've got a "rare bird" there. Enjoy the unique experience for as long as you can, 'cause you'll not likely find any more of the treasured Soundmaster heads!I change them when I break them— which I never do— or when I get sick of the sound, or get excited about getting a different sound, or need a different sound for some kind of musical reason. It has to be pretty dire, because I hate changing heads.
If you do not know how good or bad it sounds, then I'd recommend NOT changing. This goes for all music equipment: drums, heads, cymbals, guitars, amps, etc. If you can't tell if it sounds good or bad than it creates two issues:My bass batter head is a "soundmaster". I have no idea how old it is, nor do I know how good/bad it sounds or if a new head would change the sound. Any input?
