I have a realist pickup on my bass. I have been having problems with having a consistent tone with all my strings. A noticable difference in tone can be heard when switching from E and A strings to D and G strings. Assuming the problem is not the strings, then could it be possible that the pickup is affecting the acoustics of my bass? Of course, all my orchestral playing is done acoustically and not plugged in, but the pickup stays on my bass. Since the realist is under the foot of the bridge on the E string side, maybe it keeps the bridge from having total contact with the bass? I dont know....just an idea. Anyone have any thoughts?
