Thanks guys!
The 506 is awesome! I don't have a bad word to say about it. It's effortless to play, the neck is so thin and it's a very light bass. I've not actually played either, so unfortunately I can't compare.
Out of all the basses I own/have owned the 506 is by far the most comfortable bass to play, and one of the best sounding too!
I'm sure you'll be fine with the build mate! Keep me posted on how it goes! Haha, maybe
