I've had a distortion pedal, tuner, and a mic stolen, all at different times. I never leave any of my guitar's or amp's sitting on a stage unattended, or unattended at any time in public for that matter. Even when loading up, one of the band member's will stay with the van or truck while the other's go back in to bring something else out. Anytime you leave a guitar unattended your taking a chance.
