3 coil Sterling? No, I'm talking about the MM SUB. One of the newer el cheaper import ones. the sea foam green maple fretboard one to be exact . Yes, 3 knob active.
What Duncan was referring to was the EBMM sterling, which had special switching for series, parallel, single. They were not referring to sterling by music man brand. It should work on any standard stingray style pickup. They came standard on my Warwick FNAs, which have Warwick's MEC version of a stringray pickup. I love that preamp. The slap contour is very useful. Basically it is a bass boost/mid cut, with trim pots inside to adjust the amount of each.
I would put one in my OLP MM2, which also has an MEC stingray style pickup, but I do not want to deal with routing for a battery box, and perhaps the preamp as well (not much room in the cavity), so I am eyeing the stc-2c-bo preamp instead, the 9v fits under the plate where the 3rd knob used to be, and the preamp itself is all one piece with the concentric/stacked bass treble pots. I'm sure it won't be quite as nice as the 3 band with contour, but hopefully it is in the same ballpark.
Ultimately I want that Duncan 3 band slap contour preamp in my sr500 as well, but not sure if it works with a 2 pickup bass with blend control. And hopefully I could get a few bucks for the bartolini mkI preamp that it would be replacing.
And about a stingray or bongo purchase vs a 115, isn't that like asking, McDonalds or Mortons? Huge price difference between those 2 items. Even the cab plus preamp option is significantly less than either of those USA made EBMM.
And to @Linnin , yeah I tried one of the active dimensions, even the MIM, and it really had a stingray type feel to it. They were all Leo Fender's babies anyway, but the dimension is like getting a stingray with a fender logo or headstock. You really can't go wrong with either though. And then there are the G & L L basses too... They would all have been fenders had Leo not gotten sick in the 60s and sold to CBS. Sterling Ball would just be selling strings now.
