John Rossi is no stranger to Maury's Music. He purchased a Martin OM-28 here last year, and almost immediately returned to have a Trance Audio Amulet MV installed. Since then, he's been back a few times for some routine set-up work. Today he dropped by to have his Amulet preamp adjusted, and his brother came along for the ride. Well, we can't have uber-talented guitarists coming here without aiming the camera at them, now can we? John is playing his OM-28 and Vinnie is playing a Martin 000-17. Check this out!
