It's been awhile since I dug it out, and I miss it, but it can be impractical and yet I would never sell it. For me it was best in small group situations where I can hear everything clearly. And as a singer I prefer not to have sing too much and just play fretless. Fret markings were totally useless to me, as you had to adjust for each note most times anyway (subtle adjustments). Though I have used it for some blues and reggae gigs, the fretted attack is very different and necessary for most work. The standalone expression on fretless is unbeatable. Special thank you to Jaco, if not for him we wouldn't be even talking about this...
