This Modified SUB is far too quiet...

[May Cassidy]

I recently put a Seymour Duncan SMB-4A in my Sterling by Musicman Ray 4 and upon plugging it in found I had to turn my amp all the way up just to hear the bass at low volume. I've tried new batteries and adjusting the pickup height so I wonder if I wired it incorrectly? I put the green, white, and bare wires together on the port labeled "GND" and the red and black on the "IN". Any thoughts as to what may have happened and how I can fix this?

Cheers,
Doc.

Just try other wiring combos until it sounds and works the way you want. That's what I did with a generic pickup that didn't have a color coded wiring diagram.

You wired it in parallel, which will reduce the output. The standard wiring on a SUB is series. However standard wiring on an EBMM Stingray is parallel. To wire that pickup in series, solder black to "IN", connect red and white, and solder green and silver to "GND".

Also, that's an Alnico pickup, versus the stock ceramic pickup, which will change the sound as well.
