It's been a few years now, but I attempted to own a Spector Performer 4 on October 2022 (if I recall correctly), and the process only failed due to a company refusing to send me another after issues with tuners on the 1st bass, a broken neck on the 2nd (FedEx ground destroyed it, not my fault nor Korg/Spector's), and more tuner issues on the 3rd bass. I fully intended to own one in white, and it did look and feel great in person-I remember thinking it was quite comfortable back then, and the Indonesia factory pickups weren't bad at all. I loved it was passive, as that is something I definitely prefer in my basses (or the ability to bypass the preamp.) I was annoyed at the company who sold me the bass for having a "policy" against sending me another bass for a 4th time, especially because the second bass was destroyed by shipping. The tuning machines worked well out of the box, but soon started slipping while tuning, and wouldn't hold a strings tension beyond a certain point ( and got worse and worse-often all of the sudden the other tuners will stop working as well.) Knowing what I do now, I would have just switched out these Gotoh GB707 replicas for authentic ones for cheap, but the company's response to my issue-and KORG having NEVER responded to my support request over email-made me lose interest as something that wasn't meant to be.
It is very possible that the current 2023 and 2024 new Performer 4 line does not have bad tuners out of the box, and I was just unlucky receiving basses with a bad batch of tuning machines, so do not let my experience necessarily deter you. I also never hated the bass. I forget now, but some of the samples may have had a few sharp frets, but nothing difficult to solve. Truss rod worked on both non-broken samples, pickups were consistently decent. If I had spare money, I would buy one in purple to modify with DiMarzio pickups, leave it all passive, and buy a Hipshot Xtender and 3 regular Gotoh tuners due to my fear of these failing in the future! But again, I may have been unlucky, and another bass from Indonesia Cor-Tek I purchased recently has no such stock Gotoh-style tuning machines issues.
If you love the shape and it's personally comfy, it definitely could work out well for you. Try ordering from someone with a good return policy. Despite my "bad" story above, I never hated this "entry level" bass, and was prepared to make it work had it not been for my unique issues. I found a great, new MiM Fender P bass soon after on sale, so I closed that chapter then-the only thing that keeps me away from "regular" Spector besides the price are the active only electronics, but IME, the shape was comfortable (the Performer 4 is specifically a bit different thickness-wise vs the normal Spector shape every body loves/hates, but it still is very much a Spector bass in spirit.)
