Description
I own a Yamaha FSX5 and have been frustrated and a little worried about the strap button… it is strangely small and my strap has slipped off a few times.
I was inspired by the Acousti-Lok Strap Lock Adapter for TAYLOR Guitars (which unfortunately does not fit onto the Yamaha's strap button).
I made my own version of it that fits the Yamaha and allowed me to install a Schaller strap lock button/pin onto the guitar. You can still access the battery compartment with it attached too. I printed it with PLA+. I tested the strength on a test print by trying to pull it to the point of breaking with two screwdrivers and wasn't able to break it - its more than strong enough for this purpose.
This may work for other guitars but I make no guarantee and if it doesn't, please don't give bad rating - it was designed specifically for the Yamaha FSX pin.
If you use this I would appreciate a Boost and picture of it on your guitar!
Push the nut into the square hole on the first piece
Put that piece on the guitar with the nut facing the guitar
Put the next piece onto that one pushing it in place. It is and should be a tight fit. The circle should be facing you
Screw through the guitar pin into the nut. I highly recommend using loc-tite as this will spin and work its way loose.
