all you need is 2 old tin cans and bash the fuck outa them while recording

that will give you a nice Tr00 drum sound....

as for souble bass drum machines, I don't realy know of any, if I ever needed synthed drums (very rarely I can assure you) then I used a PC program like fruitloops and made a double bass beat in that and then recorded that as a wav file etc. etc.

and used that.

and anyways a live drummer always beats a drum machine.

(lets all play spot the terrible pun)
