I'm thinking of buying a Kolstein Guarneri bass. He is making them with either maple or poplar ribs and back. What is your take on what would be better, and what are some differences tonally? This is a smaller bass almost a solo model size (it has the sloping shoulders) so bear in mind volume and projection are a concern. I'm thinking the poplar will give it a very unique sound and the maple will be more bright sounding. What do you think would be best, TBers?
