Most of the F basses I've seen have solid swamp ash bodies, but recently I've seen a couple with beautiful tops. There's one in particular I have my eye on, it's a BN5 with a gently spalted maple top with a "cherry burst" finish, and a birdseye fingerboard. My question is, what should I be looking for tone-wise from this instrument? Do the F basses with tops sound any different from the ones without? Is there anything that I should know about tops in general, and specifically on F basses?
