Vintage Simmons Drums (UK) Users Group

Hi my name is Jeff.  I am 15 years old and my dad introduced me to 
Simmons drums.  I have been watching ebay and reading your posts 
here on this site and I have learned alot about these drums.  He 
finally bought me my own set of SDS9's.  I have a few questions over 
these drums.  

First off does anyone know if the Alesis D4 would be a better brain 
than my old broken SDS9 brain.  I love the sounds I get from my SDS9 
brain but the brain must be broken because I can not save my kits 
that I make and when I hit my bass drum it makes very little to no 
noise.  I want a new brain anyways because I want to add another tom 
pad.

Thats what i have now Thanks and Hi.
