Hello friends of the low end, I apologize if this question has already been discussed. I recently over the last couple of weeks acquired a couple new basses to my line up, an ESP/LTD Surveyor-4 and the ESP/LTD Surveyor-415. I love both of these basses and have moved them to the front of my guitar stands. I know the electronics pretty well, I mean come on, it's pretty straightforward. Here is where I would like your two cents: when I engage the coil tap switch on my Surveyor-4 you can clearly hear the difference between the single coil and the MM humbucker but the volume of the two is closely related. In the case of my Surveyor-415 however the volume between the MM humbucker and the coil tapped single coil is so far apart. It is almost as if the MM humbucker mode is twice as loud as the single coil mode. Is this normal? The only difference between the two basses is that the four string is stung with Cobalt Slinkys and a rosewood board and the five string is equipped with Regular Slinkys with a maple board. Is there anything I can do to help the single coil mode be more prominent? Making extreme modifications isn't really an option. Thanks!
