...but that is something you should find and make for yourself...

if you search, there are a lot of soundbwoy alarms floating around... shit, if you search you can find instructions to make one of your own...

i made a raggae mix and borrowed some alarms, but twisted them up in soundforge...

also, if you get one... find a way to fire it with the song. a sampler is great, cuz it sounds dope when you trigger the alarm with the beat.
