Hey All, Just got a new bass, and it's got an SD 3-band with two trimpots inside the cavity. There's no switch or push/pull function for the mids. The switch you see, is for series/sc/parallel operation. I would've thought that one pot is for overall gain, and the other maybe being the overall frequency of the mids? There's no "slap switch", so I can't figure this out, as I'm not hearing a difference as I turn the pots' dials (while I hit the strings). Any help is appreciated!
