Not very exotic, but I have Strat switch tips on my Teles. Got the idea from Mr. Richards. The shape has its advantages and disadvantages- for one thing it's less of an obstruction to reach that first knob, especially if you generally stay on one pickup setting.
A disadvantage is- if you
are a heavy pickup switcher it's harder to do that easily and quickly. Duh, lol.
To be clear, I kept knocking the stock Tele tip off, until I finally used teflon tape or epoxy or something to keep it on there. That tip flew off during a gig once, but I was able to find it thankfully. But that stock one is so round and large...I couldn't 'un-see' it once I became aware of hitting it with my pinky, if you get my meaning.
