I love a bit of slide guitar, it's probably the most soulful style of playing, and when my musical collaborator Phil Ockelford mentioned he was needing a guitar-mounted slide holder I was only too happy to oblige.
This easy little print is a stick on holder for a Jim Dunlop 223 Brass Knuckle Slide, the kind of slide Phil uses. It's essentially a tube with the bottom and top ends open, but with the bottom end also having a lip to stop the slide from falling through but which also is wide enough for a finger poke out when donning the slide. It has two rotating mounts for suction cups (which you'll have to find yourself, I use 20mm cups with 7mm buttons) which means that the holder will stick on flat topped and bowl topped guitars, and anywhere on those guitars which is most convenient for you. You can therefore grab the slide during your solo, play that killer slide passage and then slot it back in when you're done.
I sell these through my Etsy store (www.etsy.com/uk/shop/enterprisexddesign), custom-made for whichever slide you happen to use. It'll be delivered fully assembled, complete with the cups. So you're welcome to use this one or, if you need one custom-made, just drop me a message!
