Hello all. A while ago I picked up a pair of unmatched 15" Zildjian A's (one '60s, one '70s, both very light), and it turns out they were so buffed that they've taken on that pie-tin tone due to being overheated. I liked them at first because they were so light and fast, but then realized they basically sound like crap. Anyone ever had any success with any sort of rehab method for this, like reheating them and trying again on the sound, or something else? I buried them for a while to give them a bit of patina, but it didn't really change anything. They sound a little better if I use one over top of a relatively heavy Zilco I have, but together they are just meh. Thanks for any assistance.
