    Hi guys, I have a bass that has been upgraded to an opb-3 with a stacked bass/treble knob. As you can infer from the title, they are stuck together, so if I want to boost the bass, the treble also boosts, which diminishes the utility of the preamp.

    I don't want to force them apart because I fear I may break it. Any tips?

    Loosen the set screw on the top knob, slide the knob out half a mm or so. Tighten the screw.
