Vintage Simmons Drums (UK) Users Group

Hi guys,

I'm looking for a Simmons drumset, so I found an AD about an SDS7...
The price is good and the kit is complete (drum brain with 5 sound
modules, 5 pads - bassdrum included-, eprom burner, quick selector
pad). The AD mention a problem with the drum brain: sound memories are
lost. I asked him about that and he told me there are some
"rechargeable packs" that must be recharged once in a mounth; these
packs are used to keep the preset stored in the drum brain...
my question is: 1)how can I restore the preset drumsets in this sds7?
2)is it worth to buy it as is?


thanks

Fabio
