I've been thinking about building a custom bass for a while now. I'm a short guy, however, and weight is a very important factor when playing long shows. I own a 'Ray with an ash body and it seems much heavier than my alder P-Bass. As you probably know, it does have a wider body than the P-Bass. Even so, I'm concerned about this considerable weight difference. I'll probably go with either alder or ash for my homebuilt. Originally, I wanted a natural finish, but I'd be willing to do a sunburst or opaque finish on an alder body if I thought it would save me some back pain. Please give me your thoughts on this.
