I think that's exactly it. And yeah I've seen precisely one Coral Red Caprice for sale which I think was bought by said TB'er. The EB passives are amazing but it's not an easy niche to break into when you're known for active basses and there are SO many variations on that classic P & P/J theme, even if they are really unique. Hopefully just a matter of time before they catch on. That 6-month turnaround is pretty rough lol.
6 month turn around is standard for any build of an EBMM bass if you want one not in stock. Not limited to just the Caprice.
