Rolling Guitar amplifier!
I found a piece of gear I have (a tascam CD-gt1 mkII) google it.. Let's me plug in my guitar and have a bunch of cool effect's that play out through the Aveo's stereo speakers. Now I can jam on electric in the park, no electricity needed! It helps that I have an aux. input jack on my stereo.
Just thought this might be of interest to any guitarists out there.
