So I'm in the middle of two bass projects.. one 6 year old warmoth with a bass tremolo and a much less serious SX 5 string fretless bass revamp. Searching the internet for parts for both projects I stumbed upon a dual output jack... this one has a 1/8th hole and 1/4 standard.

So then it got me thinking... I could put a kill switch peeking out of the little hole but that would probably be in a bad position. Then I was thinking I could wire some kind of 9volt powered headphone amp through it... which would probably be too hard for me and I would guess eat through batteries fairly quick. Some kind of onboard "effect" on/off switch... maybe a gain boost?
So I'm interested to hear what YOU would do with this jack... LED on/off toggle switch? Cigarette dispenser? I'd like to hear some crazy ideas as well as realistic ideas!
