There's loads on ebay. Yes, shipped from China. I bought a roasted flamed maple neck there for about a 100 quid. It was stunning. I didn't end up using it though but I know the basschatter who I sold it to liked it a lot.
I couldn't say if the fingerboard was real rosewood but it looked good. Nice and dark.
My take on playing music is that the player is actually the instrument, the conduit for the music. A bass is simply a tool for the job.
You have your favourite tool, it's ok to change it so it's up to the job at hand.
Imho of course.
Shielding the whole cavity can be bad for tone? Interesting...never heard that one before. Can you elaborate? Kind of makes sense but I'm no expert with electrics βΊοΈ
I put a set of Gotoh Resolite GBR640-XN (X Nickel) on a custom shop P I used to have. They were a perfect fit and not new shiny chrome. They looked the part and were so much better in operation and balance.
Reverse wind gears like the originals. I don't think they do the forward gear version (GB640) in X-Nickel unfortunately, soon got used to them though. Recommended.
