" I would go with the guy that says send it back to Kyser with $10 and they wills send you a new one."

They don't even do that any more... You send the busted one to them, they send you a new one...

But ya gotta talk to them like they're 4 years old... I send them 3 busted ones... they sent me 2 replacements... after saying they were gonna send me 3...

I hadda email 'em back and give 'em a gentle boot to get my 3rd...

Probably because you don't leave them on the guitar for long periods of time...
