Hey folks... I have a set of Schaller straplocks on my strap (which has chains and loops and all sorts of fancy heavy things on it). When I first installed the straplocks on the strap (when I bought the strap new), the threads of the schaller didn't go far through the strap since the strap was thick. Meanwhile, my guitar player was basically anchoring his straps to his guitars just by putting the screw with a washer on top of the strap itself through to the guitar. He ran out of washers. I had one that wouldn't fit on my strap. I gave it to him to use. Flash forward a few months.... Playing a show, in the beginning of my last song, the strap lock on the upper horn pulls through the strap, and the bass is now resting in my hands. Needless to say, my hand was starting to hurt. Thank god for the combo amp that was close by. I leaned the tail end of the bass on it. I was able to complete the show without the strap doing anything good. And, I didn't miss a beat... So, I'm going to get a thinner washer, and NOT give it to my guitar player.
