Still loving the 4003, Great playing and sounding bass, did have to set it up a bit & drop the action, but it wasn't that far off. Bizarrely, finding the back of the neck a tad "sticky", heard a lot said about it on the other US based bass forum, but never experienced it before. Thankfully, guitar polish, buffing and playing it has helped.
The case is more knackered than I though. The inside really smelled bad, Febreze spray worked for a bit, but it's starting to smell again. Noticed even more damaged bits recently, so a new case is on the Christmas list.
Love it, but still loving my custom Faker too.
