A short comment from Marius on this bass was:
The bass arrived safely yesterday and is an absolute dream to play. Woohoooo! I love it!
Best craftmanship and looks and the sweetest p-bass growl ever. It is an absolute joy to play.
I have p-basses from fender, alleva-copollo, custom shop and several others but this one beats all of them.
