So, I've had my Bravewood 'Sting' relic/replica since November last year. An incredible bass but it suffered fret buzz quite a lot. I put this down to tuning it to Eb, neck relief etc.
I finally got round to taking it to me local tech, 'Andy Crockett'. He said he's seen this before and could sort it.
Well he eventually did a fret level and it made no difference. Very strange.
Andy said that's also happened in the past, where he just can't sort it. Everything is as it should be.
Last ditch effort, Andy said, 'try changing the strings'. So I picked up the '83 JV Squier P bass which had a set of lightly used Swing bass (tuned to E this one) and swapped the strings over, making sure to put the Bravewood strings on the Squier.
Hey presto, Bravewood almost as perfect as anything else (detuned to Eb too) and the squire had developed the Bravewood problem, only worse.
I don't know what the strings were, but they were nickel wound and I think had lower tension.
Anyone else come across this problem/fix
Here's a gratuitous picture of the Bravewood
