Yet more iPad love from Alesis with the Ampdock - designed for the guitiarist, you slip your iPad in to it - much like the IO Dock and DrumDock.
With input and output gain control, two assignable control knobs, it comes with Jam Up and Amplitube amongst other apps.
You plug your guitar in to the Ampdock, then a dedicated footpedal with program switching, bypass and a rocker pedal for volume and wah duties sits on the the floor connected via CAT5 cable.
