This maybe for new bassist. This is something I just discovered all this time I was thinking I had my EQ setting on my amp set flat and it never sounded the way I wanted. Heres the discovery, after looking closer at my manual my Low is 40dB @50Hz, Mid 30dB @500Hz, HI 40dB@10k Hz. I was thinking that flat was 5 for (Low/Mid/HI), but now my setting are Low 5(20 dB), Mid 6.7(20 dB), HI 5(20dB). Now I know how to better adjust my EQ, it's like having a new amp.
