While discussing bass stuff with a colleague today, I expressed interest in a certain bass with a 9pc maple/walnut/padauk neck. He said It'd be a "bad investment" because multi-piece necks with different woods have less overall stability than say, all maple necks. His logic: As the different woods of the neck age over time with temperate & humidity, they naturally swell/shrink at separate rates which can lead to warpage. I know companies like Dingwall guitars use 5pc all-maple necks, citing enhanced stability... Comparing this to my bass with a 5pc maple/walnut neck that constantly needs truss adjustments (much more frequently than my other basses) makes me wonder. Thoughts? EDIT: Debunked by the fine members here, gonna give said colleague an earful on Monday.
