I’m in Orange County; if it’s local to me I’m happy to take a peek and report back.....when you say LA what part you talking? As others have said LA is big and getting to the otherside is a 2+ hour trek at times.
It’s been asked a few times with no response but what kind of bass are we talking about here?
Another option and probably the best one....there’s TONS of shops in the LA area. Have your seller take it to a shop for an “inspection” that you can offer to pay for in advance. If it comes back with a clean bill of health, then the deal is sealed. If not, you lost out on a few $ to maybe get your dream bass!
