This was my first encounter with Mr. Grech...
Indeed. The Les Paul Bass is 5.5kg (12.1 lbs) and Triumph is 4.75kg (10.45 lbs). Other stuff as well...
Why was I under the impression that you own or have owned a fretless JS-2 ?
I did pick up on a Guild fretless "husk", relatively cheaply, to check out(as fretless is a different animal)if it would be workable. Left in the case as a project, it took me a while to aquire all the proper parts. The ergonomics of the short scale JS basses are a bit different, a vast improvement on the EB concept, it feels more like a full scale(and I'd love to find an actual 34" JS-II, but they're rare and expensive). It's more of a novelty, and it would go out the door if I really needed some quick cash flow.
