Vintage Simmons Drums (UK) Users Group

Hello Gregory, I've tried to contact you from your website without any chance... would you answer me through this way....?

I also wanna do your modification on my sds800, as you wrote 8 years ago that you could provide the schematics, I'll be really happy if you could share it with me.

Thanks on advance
romain
