Engadget: Hello Cleveland! Or, you know, wherever you are. Are you ready to rock? No? Oh, well, maybe just a little jam session, then? Apogee Electronics (no, not the company that brought you all those Duke Nukem releases back in the day) has announced the new Jam device, which enables a digital connection for electric and bass guitars into iOS 4.2.1 (and greater) devices or into any Core Audio compatible apps on Mac. You can record straight into GarageBand if you like and use the built-in control knob to adjust your levels.
