Willem offered me a trade - his 2 high end basses against my Fodera.
We wrote countless mails before. The communication was super fast, open, kind and very trustworthy.
As it came to a deal he sent me 2 of his basses in advance.
He knows a lot about basses. A true gentelman and bass lover.
Would trade, buy (or sell haha) at any time.
300% recommended.
And also on the top of that - a GREAT guy!
