In the early 90's I bought a new 5 string fretless Stingray. I thought I needed a 5 string, which I didn't, and for some inexplicable reason got a fretless instead. I never really got the best out of it and had to sell it quickly for a huge loss to fund a move abroad. I still haven't bought a 5 string and have done ok with a Hipshot D Tuner instead.
