I have had the privilege to work on a couple of Wals since I started this crazy hobby and, without any hesitation, they are my favourite basses.  Everything is SO well engineered and the instruments just feel and sound - great!  It's one of the absolute delights of the regional Basschat Bass-bashes because the kind folks round here let maniacs like me actually pick them up and play them. So, anything that I can do that can keep a Wal working or get playing again is always of interest.
