Greets all. Thinking about a change for my recent trade grab, a Czech-made MTD Grendel 5. Great feeling, playing, sounding bass, but the singles can get noisy. Used to have an SF-2 before i went away from racks. Im thinking of v/p/f/f which would reauire a bit of routing that im okay with.  
Questions:  
what is the viewing width of the 4-string JZ magnets? Ive got a 19mm 5 spread over a 4 string size pup. The poles are all the way at the end of the covers.  
Also, i know i shouldnt ask, but how much are wood covers? Thinking weng? to match the board.  
 
Thanks all, its possible im just angling for a reason to visit the shop again. ;-)

Hi Andrew; I do think it possible that you would love to visit the shop again.
 
 

Can you measure the overall length of both pickups? Not sure if MTD uses the traditional longer bridge pickup or not. Out 4-string JZ pickups have a 2.6 inch string spread above the pickup, so it's not going to work. The way the pole pieces interact with eachother, the field is larger than that with a bar magnet of the same combined length.  
 
You're going to have to route to use our pickups. Any of the 5-string variety will work, but there will be a lot of chips flying to fit in either MXY56 or AXY56.
