I have a 2006-7 Ibanez SR400QM (4 string) that I've been looking into replacing the pickups on. I installed a Bartolini 3-band active/passive EQ system and would like to get better pickups than the stock ones to make most of it. But after looking at replacements on the market and the size of the pickups on my bass, it looks like I have one of the older models with the 4.5" long pickup casing as opposed to the 4.25" Bartolini MK1 and Nordstrand pickups that now come with the higher end Soundgear models. The pickup is still the same 1.25" wide so I'm wondering if maybe previously Bartolini made 4.5" 4-string pickups and then there was a multi-company shortening of the pickup length
. Either way, if anyone has any pointers as to if I can get an old set of name brand pickups or if I should start looking at custom manufacturers, I'd appreciate it!
