My MM5.2 cost me $115 shipped from Jay at Blueberry Hill Bass. I had a great experience with Jay and Carey and I highly recommend going through Jay to get yours. The wiring notes that Carey included are quick and to the point, offering ways to wire it up in series, parallel, or with either of the coils on their own. I had my pickup wired up and going in no time without having to spend half an hour on Google digging up wiring schemes.
The bass I put mine into is a Modulus Flea 5 which of course meant I had to route the body since I was replacing a four string Bartolini MMC. The difference was pretty noteworthy. Wired in series I get a really great rock tone out of it. It's aggressive and middy, which is due to the series wiring (I haven't tried parallel or singlecoil yet but a switch mod is on my list of things to do sometime soon). It cuts through the mix without hardly any need for EQing either on the guitar or at the board. The F5 already sounded good with the Bartolini but replacing it with the MM5.2 was like putting a Corvette engine into an Acura NSX.
I'm actually sort of surprised Modulus would put a Bartolini into the Flea when there are pickups like this available because it sounds so much more appropriate. I love the way it sounds and I definitely recommend it.
