I really like this pickup. Everything about it is just right. I've placed mine 8.5 cm middle of pickup to bridge saddles. For me there's not much to wish for. Decent? What would you like to change? My bass is nothing like an MM (alder body and fretless aluminium neck), but this pickup makes it sound like one. There's no wonder why Stingray is one of the most sought after musical instruments, one of the few (or only) classics after Precision and Jazz. The pickup sounds best in parallel (if you like the classic Musicman sound). It's OK serial but slightly boomy. As single coil and in the position mentioned above I prefer the "neck" coil, but it's a bit noisy and prone to pick up interference. I've compared it to a Bartolini MME in this bass. SD is rock 'n' roll and Bartolini is... I don't know. No character, no sex appeal. SD has plenty of it.
I haven't tweaked the sound with eq. With the SD I feel no need for it. Maybe the Bartolini comes to life with a good eq.
