My Pearl set is dues for new heads..........these are over 25 years old.
I haven't kept up on any new tech ( if there is any) on heads. Currently I am using pinstripes on top and bottom.
Back in the '70's I saw a local band play and the drummer had his set equipped with Hydraulic heads ( brain****.......can't remember the the maker). Are these still available..........and are they still in vogue?
Any suggestions???
