Yeah if it has to super quiet the contour/loudness control won’t work.Yeah, I agree with this idea too, and the suggestion of amp. It's more money but the GK has the headroom needed to get loud enough for a band situation, plus can be turned down enough for bedroom practice. I will note however that I cannot use either the contour or the vintage settings on my Rumble100 in apartment and keep the bass from penetrating walls and floors. I do better by turning down the low bass in the EQ and then adjusting volume on whichever bass I am using so it is just loud enough to be properly heard in the bedroom. If my wife can hear it or feel it in the adjacent room, it is too loud. Also, I try to only play during middle of the day, most people in adjacent apartments aren't home.
Or, you could just crank it up and move every 6 months, which is how long it takes to evict someone here in L.A.?
Have you tried headphones? Some people hate them. But honestly, it can be worth getting used to them. In most recording situations I have been in my amp has been in an isolation room and I had to use headphones while recording.
