I have an amp that has passive and active inputs. When i plug my active bass into the active side i have the gain at noon and volume at 1-2 o'clock. When i plug into passive side gain is at 9 o'clock and master is at 10-11 o'clock. It might just be me, but i find the tone of the bass to be more to my liking plugging into the passive side. I know older amps only had passive inputs and isnt the active side just a signal cut anyway? This isnt hurting the amp is it?
