I've recently been having a fair biit of headless GAS (I know it's 80s but I like it), and i'm completely in love with my jazz bass at the moment which gave me a bit of an idea. I googled 'headless jazz bass' and didn't find anything, so I did this little mock up on paint.
Don't worry, I wouldn't dream of modifying my jazz in any way, but I am building a project jazz at the moment for which headless could be a possibility. Just thought i'd post this to see what you guys think.
