They may not advertise them, but it may be worth querying whether they have them. They were selling a "Stealth" Jetglo recently, with the black scratchplate & TRC, where they'd customised it in house. Seen these on eBay: Black Plexiglass Vintage Style Truss Rod Cover for Rickenbacker | eBay

Always thought Rickysounds had black TRC's in. Might be worth a query if nothing else. Congrats BTW.

From what I've read, they're an iron & cobalt alloy, so I would assume that they would more be prone to rust rather than any steel based string (especially stainless steels).

What's the deal with Cobalt's? Are they coated with cobalt, a high cobalt content steel or pure cobalt? Reading the blurb on the EB site, there is no info regarding what the cobalt content actually is, and how it contributes to the sound. Confused.... Ah, bit of t'interweb digging... an alloy of Iron & Cobalt. I'll stick with the Dunlop DBS.

@Beedster's dog doesn't like slap bass either.

The guy who runs the local rehearsal room has said he's rebuilt & renovated a few in the past.

Lets hope it gets sorted, and that none of your other basses are affected.

Obviously, a tortoiseshell scratchplate sounds better than any other colour.

IIRC, G&L's have a grub screw on the side of the bridge in order to stop the saddles rattling. Maybe tighten the grub screw, as it sounds like a 'loose' saddle.

Some shops will offer 'commission sales', where they will add on a percentage, but you have entrust your instrument to them to look after. Unless it's a trusted specialist, not sure that it's viable these days. As has been said, part-ex prices are often insulting, in order for the shop to make it worth their while. Not viable. Private sales, either here, the Bay of E, Gumtree, Reverb, or some other site would be the way to go, but needs a lot of trust, and careful packaging if you're going to post. Thankfully, the marketplace on BC is great.
