Keeping a guitar

If you are not opposed to using mods then there is one by Scumbumbo called "Keep instruments in inventory". I have been using it in my game for quite some time now and it works perfectly. Here is the link if anybody wants it https://scumbumbomods.com/#/keep-instruments-in-inventory/ You can probably also find it by googling the "Scumbumbo Keep Instruments in Inventory" in case you don't trust the link.

I know he passed away but his wonderful mods are still be kept updated by another mod creator.
