Ok, obviously the construction is different, that's not what I'm asking. Just to bring you all up to speed. I play a warwick thumb bolt-on 4, my first 'good' bass. The other day I walked into guitar center (canton) when a friend of mine, who works there, nearly scared me to death! "Dude, you have to play this bass!", it was a warwick thumb 5-string. After taking it off of the wall he handed it to me and said, "It's a neck-thru". I had never played a warwick neck-thru ANYTHING before, so I had no idea what to expect. I plugged it into an SWR stack and started playing it. WOW! This thing sounded nothing short of explosive! It was unlike any bass I had ever played. So here's my question: What is it about neck-thrus, warwicks in particular, that makes them sound so rich, so sharp, so... goddamn good, compared to bolt-ons!? Is it the wood, the electronics, is it all one huge conspiricy working towards me spending way too much money on a new bass?! Someone help me out here! Perhaps I made this a bit too wordy, I'll keep that in mind when I post in the future.
