Did a bit of a set-up "tweak" to this bass last night. I managed to get the action feeling even nicer. I wanted to give the neck a tad more relief - but the bridge saddles are at the bottom of their travels... and I can't set them any lower. However, it's set rather nicely, just as it is. There was a little string buzz / rattle at the heel end of the neck, and a close examination showed the fingerboard had a little upward slope at the end of the heel. Again, I bravely / foolishly took the sanding block to it, and gently took the level of it down a little.
A bit of Lemon oil on the fingerboard afterwards, and it looked like new. It's now playing even better than before, and I'm even more pleased with my recent purchase. I could still do with selling my Precision - even though it looks lovely, it's just going to sit there, looking pretty, but unused. I am determined to make more use of this fretless bass than I did my last one, especially as I confirmed its weight with my digital scales - it's 3.5kg and that included the chunky leather strap I put on it.
As you can probably gather, I am rather happy
