Alder is NOT INFERIOR! I own alder basses just because they are warmer! Ash basses are good for the thump and pop stuff which I do a lot of, and alder while also very good for that technique sounds "mellower". As far as ash not sounding good with rosewood thats B.S.! My CS jazz bass is just that, rosewood and ash! I also own basses that are maple/ash, alder/rosewood, koa mahogany/rosewood, alder/maple and all these different combinations sound different. None sounds better just different! Different tools for different jobs!!!
