2 kick drums will rock You need one of theseor one of these (can't remember if you need mono or stereo but I'm sure there's a setting in the brain to tell it what type of input you're using)oh and you'll need another jack-to-jack lead (mono/stereo?)I've tested this out with a DDrum + 2box kick going into the 2box brain and it worked no problem, although the levels were slightly different - but 2 x 2box kicks should work fine I guess
