I got a quote of 12-18 months for a Sonus 8 with almost no custom features.519 is 35” 19mm so it sounds like you’re looking for a sonus or sonus custom with 19mm spacing.
my takeaway (or one of them) from this thread is that given the inconsistent wait times, one of the through lines is that custom orders seem to take longer. So I’d be more inclined to order a stock instrument than something that’s going to require a custom neck or custom electronics/hardware. It still doesn’t sound like that’s any kind of guarantee for a quoted timeline but customization seems to be one of the things that pushes timelines way out.
all that being said, as much as I love Zon basses, for me it would 100% be about finding an existing used one with a truss rod.
Let you know in a year how it's coming.
