They're good, but you can't take the strap off, unless you unscrew the whole thing.

Dimarzio strap locks have a buckle so you can take the strap off, and the strap is secured similarly. downside to the Dimarzio is that you cannot use any strap.

Is there such a thing as a heavy riff with out chugging on the e string?
I think the best straplocks out there are either Schallers or Dunlops, I prefer Schallers, those things untrustworthy, I don't trust the "fits on any instrument with no modifications" thing at all.

These strap locks are killer. I like the pinch design. Just bought some of Musicians Friend and am very happy with them. They look good too...
