This is an advantage of a bolt-on neck. Much easier to handle fingerboard dressing!
I've adapted an old black'n'decker workmate for benchtop use. It is really useful for holding tapered things like necks and fingerboards. A bag of lead shot in the box holds it nice and steady.
I fitted the bridge feet and strung it up with a rough string height and quickly done nut.
How does it sound? Well, new bass, new strings, its going to be bright for a while.
But ... louder than Sirente, despite the shallow ribs ... easy to play, the notes seem to just come out of their own accord. This bass
works. And even though i just used some Corellis i had bought for the other bass but hated, surprisingly mean and growly down low.
Arco? No idea really as I'm a shocking arco player. Sorry. And now I've pulled it all down again to do the neck and bridge properly, adjust the machines a bit, and a few more touches to the finish.
However I have played it enough to be able to say with confidence that this bass as way better than the first one - which wasn't bad. And I can't wait to get it back together again!
