Vintage Simmons Drums (UK) Users Group

Hi,

I'm new here; hoping that someone might know how I could get 
permission to clone the SDS3/4 drumsynths?

I read at Wikipedia that Guitar Center owns the rights to the Simmons 
name. But I don't know yet if they have any prior circuit rights?

Anybody know any details?

I already have the information I need to do the clones; I'm looking 
for the permissions to use the old circuit design.

ANY help will be very much appreciated.

Thank you,

Randaleem
