this is probably going to sound like a stupid question but i own a 4 10 cab with the speakers frequency range being 40hz-3.5khz. now at about the 7th fret on the E string the speakers sound as if they are farting out but i don't understand this becasue that note should be well in the frequency range of the cab, however, this doesn't happen with the other strings. i'm running active pickups on my bass with EQ... could it be possible i'm over EQing through my bass or what? i don't know, i'm kinda slow at these things. oh and it can't be the amp overpowering because it is not clipping and i'm only running 500 watts rms into the cab which is rated at 1200 rms. the amp does have the good old 9 band EQ so could i be over EQing there to? i don't know. somebody explain please.
