it's not the scale or the nut width which would be in question. it's the shape of the neck heel. it might be ok, but then again, it might not.
try asking warmoth if it will be a good fit. or even send them a tracing of the heel for them to route the body for a suitable neck pocket.
they were sealed lifetime lube tuners on those new jagmasters, weren't they? i thought they wouldn't need replacing. it's possible a set like these would fit, but it's always difficult to know if the bushings will fit the old holes etc. click on the "specs" tab
