The rig I use is a GK 1001-RBII with a GK Neo 2x12 cab. Lots of great reviews and recommendations. The bass I use is an Ibanez GSR200 4-string. When I bought it (for $200) it was just what I needed. Something to get me started. My question is whether or not this cheap bass will impact and, ultimately, hinder the sound and performance of my amp and cab. I ask because I notice when playing live and having my volume on the amp at around 50%, I get that muddy thump when I hit notes on the E string fairly hard. I know the Neo 2x12 cab isn't a monster, but I figured for the price it'd be able to handle something like that. Would a $700-800, higher quality bass more than likely do the same thing or is it just my rig? Thanks in advance.
