Fender Strap Blocks (black)

Perfect. I cannot play without.

Had long used the Ernie Ball strap locks, went back to a more simple setting, so I could keep the original strap buttons on my guitars. They do very well the job, come in different colours for those who want to assort the Strap Blocks to their instruments, extremely simple to put on the strap buttons.
Like any other strap lock, maintenance is necessary, the mechanical strap locks need some oil here and then, the Szrab Blocks need to be exchanged. It's plastic resp. rubber, and plastic/rubber ages and get brittle with time. Mine last some 3 years and at some point you note that they are getting rigid and brittl, so order a new pack-

Super Security for his guitar, which prevents the strap from falling out of his guitar, the best strap Blocks for me, simple, solid, effective.

Good solution for those who has one strap and more than one guitar.
And for those who doesn't want to install straplocks.
