Bassassin Posted May 31, 2018 Share Posted May 31, 2018 2 hours ago, briansbrew said: There seems to be 4 knobs and 2 switches Jon, what is the difference in them Not really clear about that - the 4-knob active seems to be a rarity, read about them & this is the first I've seen. My bass is passive so I'm not 100% clear how any of the active ones work. Chuffed you got this one! Link to comment Share on other sites More sharing options...
