Mainly doing so so that the weight of the bass (when standing) falls more toward my body, as opposed to away, as it does now. I see that one could buy a pin that is pre-bent, thereby allowing you to try it out before having any major surgery done to the instrument. http://www.slavapub.net/Endpins-Bent_endpin.html I'm not sure how this factors in but my bass is large and I only use about 6 inches (first notch) of my current straight pin. I'm assuming the less length one uses, the less benefit of the bent pin. Anyway was wondering, of those who have gone whole hog on the the bent route, any regrets, no regrets? Also was wondering what if might do in terms of resale value to the instrument.
