The world's most metal guitar is brought to Guitar Electronics for service and documentation. James Hetfield's "So What" Explorer is the guitar that was used to record the first Metallica albums ans James's #1 guitar for the first several world tours. We got a chance to measure every aspect of the action and frets as well as photo document all of the unique markings, decals and road damage. Amazingly it still plays great and has a sound like no other.
