Jack's burst starfire would have been maple. The original one I'm not sure about. But either way, those basses both had different versatile electronics in them, plus it seems like he started playing around with inverting the pickup orientation once he got the burst one, so it would be hard to compare the wood of the two. Beyond that, wood is organic material and will vary greatly in density, weight, grain, etc even if it's technically two of the same type. For this reason I usually just let my ears decide once I play a bass whether or not it is too muddy, bright, woofy, clanky, bonky, raw, dull, slippery, zippy, or donky.
I will say though, if my mahogany 1970 SFB was any brighter in tone, it would probably end up being too clanky for my style of playing. I'd probably have adapted to it after a few weeks, but it felt/sounded just right to me right off the bat
