i use a plastic dunlop thingamy (with blu-tak inside so it doesn't come apart!) on the strap button on the horn, and one grolsch thingy with a plastic dunlop fella on top on the other.... why?
the grolsch thing kept unwinding the screw on the horn (guess cuz i throw my bass around my head alot) anyone else find that to be a problem?
on the other end i found the plastic dunlop unwound itself and kept popping off... so i put the grolsch thing on as well... doesn't happen with the grolsch underneath cuz it cant move enough to come undone.
a little OTT and very much bodged, but it seems to work!
