Designed iPod friendly, BlueBox’s miJam series lets you add your own noise along with whatever’s coming out of your iPod. Each of these three devices includes a minijack-style connector that attaches to your iPod’s headphone port, and an audio output port that you’re supposed to connect to headphones or a separate speaker system. The instruments pass through your iPod’s music, adding beats and additional instrumentation as described below. Prices are $30 (Guitar), $40 (Mixer), $30 (Drummer). Via iLounge
