WHAT DOES IT DO: If you want to practice the guitar, but often find yourself in less-than-guitar-friendly places...it comes in two models, one with four frets that's great for playing chords, and one with six frets that's perfect for scales. It has genuine guitar strings and a strum pad to keep your rhythm right — so it feels almost like the real thing, only without the noise. Collapses down to fit comfortably in a pocket or bag.
HOW MUCH: $25-30
FUN FACT: Peter Bush doesn't need this - as he plays his full bass while in the studio
