I don't know about other people but I've never needed to change the hardware on my Harleys. Not saying I haven't done it, I put @KiOgon switched tone pots in two of mine because they look cool and it was fun to do. I also put black strings on my two matt black ones, not because the HB strings are poor - far from it - again just cosmetic tinkering.
I'm glad these basses have arrived, I've a few low priced items in my basket waiting for something to get me into free postage territory. Included in this are some of the new higher quality HB strings (including a set of flats) which I'm excited to try
