I've desided to go with a Swamp Ash body for my first bass. I was looking at Larry's Gallery Hardwood site. After e-mailing him about what I wanted, he responded saying he has two piece unglued body blanks. I've also noticed that some builders use two pieces and some use one. What is the difference between a one piece body and a two piece glued together? Are there tonal differences, or is it just cheaper to buy two narrower pieces and glue them together?
