I'm dealing with a weak signal from the high E string, from the cheap modern bridge pickup of this old custom build; the narrow blades don't cover the first string as fully as the center strings. I posted re pickup on the TDPRI pickup forum. It occurs to me that the saddles are part of this problem. Multiple haphazard notches, from many years of assembly, disassembly and experimentation. It seems obvious that I should file and sand the saddles smooth, then file a shallow notch in each, half the string diameter. Or are notches even necessary - would smooth saddles be OK? Thanks for your opinions.
