Sorry to hear about your injuries and hearing loss. Or ... are you looking for info to prevent them?
My daughter just informed me she has tinitis in her left ear, and she plays violin! Classical music. Imagine the SPL's from drums. I'm thankful I have always worn some kind of ear protection all my life.
I play a bunch of gear. Mostly my 65' Rogers WMP Holiday kit with a COB Dynasonic (second owner since 1971). I have a collection of fun old kits and snares that I do play regularly and a super fun TRS stand up cocktail kit (darn small stages) My band of old guys rehearse weekly and play out about 6 times a year. I look forward to this forums collection of wisdom and humour. Cheers,
