I've busted a few jackplates along the way, but none for awhile (until today). I was jamming a little this morning and I spun around kinda quickly and I hit the cable end right where it meets the jack on my music stand. The plate exploded.... .
What's annoying is after years of being a parts horder I've got rid of most of my extra parts, and don't have another jack laying around....
Or to avoid a re occurrence you could use a right angled jack threaded through the strap. Essential equipment on a 335/SG and if you use a small right angled jack plug like a a George L it will even fit in your 50's Tele which larger right angle jacks won't.
You're no longer a virgin. When it happens for the 3rd time, you know you're a player
I haven't done that on any of my guitars, since I went wireless. Come to think of it, I haven't tripped over a cord, or pulled out a cord. Wow. Another benefit of wireless that I hadn't thought about, until I saw your pictures.
