Damn! I installed my Nailbomb in my Ibanez S1220 yesterday, haven't restrung it yet, but today I was just checking it out and it just hit me, I took the ruler out and compared it to the QM2 that was once sitting there and yep, sure enough, the original pickup is 50mm, whereas I ordered a 53mm Nailbomb. shite! How much of a difference will this make? I've soldered it in place and all, the box it came with is a little tortured and the strings have already been used on another guitar. Is it worth sending it back for a 50mm?
