Does anyone have this problem: When I use my bass amplified (pick-up) I detect loss of volume from approx. half way up the F/B, especially on the G & D strings. (The bottom end is fine.) Would, say a transducer, under the F/B help volume in the upper register? Would a Graphic EQ help solve the problem? If a Graphic EQ is used what freqencies would be used,say from the note D---upwards--- on the G string. What 'on board' mic. do you consider to be the best? Your experiencies welcome.
