2 weeks ago I purchased a 4-string M.Miller signature Jazz Bass.Even though its sound is killer,when i play with my band i find that the low E string doesn't have the presence and the tone i want to be heard.I also noticed that the string has a slight lower volume than the others.Would you suggest me moving the pickups closer to the strings or is it common for this type of bass to sound like that?I've already boosted me low-low middle frequencies using equalizer...Any suggestions...
