Generic #226 - 1/4" Mono Right Angle Plug

Not as good as the switch craft (obviously since it's much cheaper) but still a good product. If you can, drill a small hole in the sleeve to solder your ground wire to. Makes life easier.

This jack works well and I can confirm it will make a solid guitar cable. My only complaint is that there is no speaker cable size available. Not a huge deal (obviously it doesn't specify "Speaker Cable" in the name), but it doesn't look like it would be too hard to sell it with the tapped cover from this jack: https://nextgenguitars.ca/products/switchcraft-285l-1-4-mono-straight-plug-for-speaker-cable.html?src=prn#write_review far as I can tell the threads are the same. Otherwise it's a great product.
