Hi.
If you are able to burn Eproms by yourself, you can download the original
.bin-file of the snare from www.simmonsmuseum.com. If not, you can contact
me under
michael.buchner@... for a replacement Eprom. The original
SDS7 snare is called "tight snare" or later "tight rock snare". Check your
SDS7 snare-card if it is a 8 or a 16K card. And check the card itself with
another Eprom, maybe your snare Eprom is still working, but the card is bad.
