the gmad is a 12mil 1ply head.
I prefer the Aq. Super Kick 1 over all other drum heads for the bass drum. It produces more bottom end and still allows more tuning ranges. It lasts as long or longer than much heavier heads and together with the regulator counter part I think they excell. Doc
A thinner head will not have more low end than a thicker head, considering they are both single ply. Also a thicker head should give more sustain than thinner head. So GMAD is the only single ply drum head available? Can you remove all the damping from the head? The GMAD sounds like what I am looking for, I just don't want to have it be pre-muffled.
