Just thought I'd check - I bought a body that is routed for 3 4 string P pickups, wondering if I can convert it to 5 string. I can fit the 5 string neck and bridge on, no problem, but I'd rather not have to widen the pickup routes. I checked Bartolini's site, theirs measure the same, but not sure if that holds for other brands. The Barts are 2.20" x 1.8" per half (excluding mounting tabs) whether for 4 or 5 (or 55.74 x 24.73 in mm). So, could some folks with other brands of 5 string P pickups measure & post dimensions here? Wondering about Delanos and Lace Alumatone in particular (will check sites).
