Brought a 22" bass drum, 12, 13, 14" toms to Precision Drum company in Pleasant Valley NY and wow-cool experience to witness and great sound afterwards
None of the drums had even bearing surfaces to begin with but they also had some other nasty areas. The bass drum head never seated down all the way in one spot. One of the toms always sounded dull. The shells are thin mahogany with some other wood ring.
Results were excellent. The three toms became way more "musical" with a pleasant sustain. The bass drum went from bad to very nice.
