Cool. How did you end up choosing the M45CBC?
I looked at the M45CBC too but it's got a different screw hole pattern and at this time there's no specific tonal reason to go down this path over the CF5CBC which should fit right in.
No haven't done it yet. I'm just hoping the Barts are different than the stock Ibanez pickups, in a direction that I like.
I also shoe-horned in a Bartolini NTBT 3.3 into the cavity to give me some more scope. Turns out I really needed that mid control
Ahhh well, you suck it and see don't you.....
