I bought the Kingston LK5 as well. It just arrived and out of the box, plays and feels magnificent. I was really looking forward to this bass: super light (<8 lbs), MTD build quality and playability, 5 string PJ, etc etc. And, it delivers. It is a well made bass, with good (decent) quality hardware, fit and finish, and excellent action. In this price point, it is in line with industry standards and has much to offer those in the market for a mid-tier mass production made bass. To be clear: in no way, shape, or form am I saying where it's made is a deficiency.
Unfortunately, I also found the tone to be abysmal: weak, lifeless, anemic. However, this is in comparison to another bass I already play. Is this unfair? Possibly, but it does tend to contextualize some personal reviews/anecdotal observations.
I am quite sure the electronics are the weak link. Although, there is a active/passive bypass, the pickups are less than enjoyable without the pre engaged. Even in active mode, the bridge pickup lacks any depth or authority.
Of course, all of this is completely subjective. Everyone has different goals and expectations. I'm usually the first one to say 'mod!', but I don't see me having the desire to do it. I am just so disappointed with it (maybe unrealistically). I didn't even want to do a video/review to post. I wanted to just put it back in the box to return, before I damaged it in any way.
Again, just my opinion (and I was so hoping to have a different experience). Ennyhoo…just wanted to relate another experience for the search algorithm.
