Yeah I wanted to know if these were like a DC in a SC casing like what Duncan does with the JB and JB-JR. I don't mind that it doesn't have the dog ears. My guess is these will still be to big to fit down into a Jazz pup cavity.
Cool it is just that 74mm spacing divided by 4 is 18.5 spacing not 19 possibly it is close enough..........t
The Bartolini spacing specs are over the pup not at the bridge. 19mm at the bridge is aprox. 18.7mm over the bridge pup (depends how far the pup is from the bridge). That's a nominal mesurment, the magnetic field is wider. BTW, if you check with a EMG magnetic paper you'll see the coil are way wider than 74mm.
Still, these pups are oem on an instrument with 19mm spacing without any problems.
