Interesting ! Thanks for the info. Sometimes I see Grinds for sale for pretty cheap ($175-275 or so) and I always think to myself that these would be really good “sleeper” basses to modify and upgrade. I have only seen the neck through soapbar ones. Good looking basses for sure. Unfortunately the ones I’ve checked out tend to be pretty heavy, and I have cancer tumors in my spine so weight is an issue. If I found a lightweight one cheap it would certainly be tempting though.Not quite.
First difference being the 'Grind' has an offset body shape and is 35" scale length. Then there's the history, Grinds started life as a USA production line bass. They were an active bolt on neck design, the 4 string being a PJ and the 5 string a JJ. Those were quickly joined by an import line with the same hardware/materials/spec. Below are my US Grinds along with the more common neck through version.

Sales were poor so Peavey switched things around.
Passive C-Series/Zephyrs were brought back with a scale length increase to 35", active pickups/EQ and a new name; "Cirrus BXP".
Active bolt on Grinds became passive neck through basses. For some reason there was a slight change to the pickups, 4 wire humbuckers became 2 wire humbuckers and the DCR dropped by 5%
Yours are Beauts ! I especially like the natural finished one and the hologram…. That one reminds me of the G Basses, which are criminally underrated instruments. I should’ve never sold the one I had way back when.
