A couple of nice easy listening ones tonight , has to be Gregory Isaacs with a my love dub mix
and an early one from Patrick Alley around 1977, I really like the vocals on this, reminds me of another song but I can’t place it yet
I’ve got one fitted to one of my jazzes which was an experiment really, I don’t play hard or dig in as they say but I quite like it, once you’ve found the right height which is close to the strings I can’t really think why you would want it adjustable
I’m not familiar with those strings as I only use flats, but shouldn’t a new bass work with any strings, I certainly wouldn’t be talking it apart testing stuff, I’d ask for a return and new one, good luck
I use the Gibson pump polish occasionally on my vintage basses, it does leave a slightly shiny finish which buffs up well with the microfibre cloth, and not sticky, maybe worth a try
When you have a bit more info you could always ask here or in the vintage fenders thread , there’s a lot of knowledgeable people there who would be happy to assist if you needed, good luck
