if your the kinda guy that likes to mess around with all kinds of crazy stuff, then maybe the jl audio amps with RIPS technology would be for you. they deleiver the same amount of power at all impedance in their operable range.
and i wouldnt necessarily call it a "beat", as it is more than just a rhythm track, but i wouldnt necessarily call it a full arrangement either............ i think the term "loop" would most accurately describe trhis.
what program you use?
and how do you propose making your buddies pay this? if they were really your "buddies", they wouldnt have done this in the first place, or they have atleast been willing to wash it off themselves.
you got kinda lucky though. even though some people dont have any reaction at all the bite, some people have such sever reaction that their whole foot would have rotted off.
glad you still in one piece!
