I'm thinking of a slight upgrade for my "arco" bass. I currently have a 2009 Calin Wultur Corsini bass. Looking at a 2014 Emanuel Wilfer 402 (also looks something like their #10) bass. I've played several Wultur basses and mine is the nicest sounding of the bunch. Fairly easy to play. It doesn't have the nicest finish I've seen. The wood isn't especially beautiful. The only problem it's had was that it needed the A string tuner hole "adjusted." It was slightly mis-drilled, causing a slight bind in the tuner. The E. Wilfer I'm looking at is billed as an "upper register" bass, allowing somewhat easier access to thumb position. The finish is excellent, the wood looks nice, it plays and sounds very nice. Nicer than the Wultur. Any thoughts on one vs the other?
