Hello! I was wondering if you could help me sort out a problem I have. I have a fender rumble 350 and it has served me well, most recently at a gig for Legally Blonde the musical. Anyway when I use this amp in my bedroom which is on the second floor the low end seems to completely disappear leaving me with not so pleasant mid range which I have to cut. Would a gramma help isolate my amp and provide me with more low end instead of it being absorbed into the floor etc? Thanks!
