I’m also guided by weight these days, especially for basses. I think, on the whole, basswood is generally light, but each instrument differs somewhat. Something that is important regarding weight, is balance. I had a Stingray that was a hefty lump, but on the strap the balance was spot on and made it feel lighter and then there’s strap width to consider, which also helps. Anything chambered is going to lighter than it’s all solid equivalent and totally hollow lighter still of course. My Casino Coupé is stupid light, but obviously not a Strat.
