| Soundwise, in my experience with doing it both ways on the same bass, it won't make a bit of difference. I didn't notice any difference in feel either. Some guys say that string through couples the string to the body better. Maybe, but I haven't noticed the difference in basses I've converted to string through.
One thing I do find makes a small improvement in sound is to have a steep downward angle where the string exits the bridge and sometimes string through makes this easier. But the difference is minute and in most cases inaudible as on most top load bridges you can get enough downward angle easily. Past a certain angle it won't make any difference.
You're set up to do it either way so why not try it for yourself? |
