I have a set of Supreme drums also, I bought them when I was 13,and I'm 55 now...still got 'em but don't play 'em anymore....
Welcome! It is cool knowing you have had these MIJ drums for 42+ years. If you no longer play them, now might be the time to look for that special young man or woman to donate them to. I restore and donate a kit about every other month. It takes a lot out of, physically, but I do it because I love the instrument. I can't play a lick, but I do what I do because of the love I have for drums. You see, my baby brother was a smokin' drummer, could lay down Bonham smooth as silk, Alex VanHalen, no problem, a little Stewart Copeland or Buddy Rich, a little Art Blakey perhaps? He had a ghost, however, he could not shake. It finally won, I decided that one day, I would again go back to the percussive arts. Last year my then 9 year old son began to show an interest in drums, and there I saw the time was right. I had already been playing hand drums for the past year and half, getting my chops back as I, too, was a player in the early 90s.
Anyway, today my body is wracked, ravaged by too many years of self detrimental activities, and just plain neglect and poor exercise habits. Can you imagine, my form of exercise, for 20ish years, was taking a handful of acid or mushrooms, smoke obscene amounts of pot, drink far too much, and dance all night, to whatever band was playing, and I have seen over 800 Pro shows, let alone all the other music, bars, fields, backyard parties, we were golden, deeply rooted in the music industry and the party scene. "The Untouchables" as it were.
Should you decide it is time to move them on to a younger generation. let me know, I can help you locate the right person, but then again, so can a great local drum teacher. Be purposeful in your search, and if you would be kind enough, would you post some pix of the kit? I would like to see it, to know the specifics of the shells and the rest of the kit. It may be that they could benefit from some of my special "tuning techniques"...they may be drums you never knew you had.
