been done before, MusicJam is looking to combine the simplest of mixer functions with a karaoke machine in its aptly-named iPod Mixer. Essentially, this device allows you to add your own vocals and guitar riffs to the tune currently playing on your iPod, which could definitely bring out the "one man band" in any musician. The mixer sports an iPod dock (presumably compatible with the iPod with video only), microphone / guitar inputs, volume sliders, tone / distortion controls, RCA outputs, and even attempts to replicate that on-stage allure by touting echo / sustain options for your vocs. The company also throws in a microphone, mic clamp, and cabling to get you warmed up, and includes "KaraokeVideos" software to turn any jam into an iPod-compatible karaoke vid. While the quality here is certainly questionable, it looks to be a solid addition to your Korg-infused Les Paul, and hey, getting you fully prepped for that karaoke circuit will only set you back $229.
