Vintage Simmons Drums (UK) Users Group

I have a set of original SDS9's I'd like to sell.
I am the original owner, they've basically been
sitting in my closet in a case for years. Drums
are in good shape, I have a rack if needed.
The only glitch in the controller is the bass drum
seems to be stuck on a very fast echo. I've never
had it looked at so it may be fixable. Let me know
if anyone is interested.
Thanks,
Rick.
