Not really.
The Grind started life as an active US assembled bolt on neck design. The 4 strings were P/Js with 5's being a J/J set up, they were quickly followed by BXP versions. None were great sellers so the design changed to an overseas passive neck through, very similar to the Zephyr/C-series sold only to the European market and which had been a very strong seller.
Thank you for the history lesson! Interesting stuff! Yeah for the next through design I think it cost a little over $450 new, and with the electronics upgrade, bone nut, and a professional fret job to have ultra low action, I have around $1,400 invested into it. It's the best studio recording bass but I would say it's a lot harder to play at a gig mostly because bands don't like seeing that many strings haha!
