Yes you read that title correctly, ThinkGeek have created a T-Shirt called The Electronic Rock Guitar Shirt which has a 7 fret fingerboard where each fret contains 2 buttons, top and bottom containing different Major chords. If you strum without pressing a button it plays an E Major of course! Now it says Major chord but I would have thought a power chord would be more appropriate, maybe it does? Using both sets of upper and lower buttons you can play a full octave of chords using the included magnetic pick. You might be wondering where the sound comes from? Well you plug into an included mini amp of course! The amp clips on to your belt so you can annoy people at the bus stop with your Black Sabbath riffs. And yes the amp goes up to 11… how original.
