In that range, the
Calin Wultur Basses are at least as good as any Upton Bass. From what I have been told, the Uptons are from Romania made in the Gliga shop just like the Plywoods from JR Music, maker of the Calin Wulters where E.Roy used to work. I bought 6 Corsini Basses for stock and was extremely impressed as were my customers who bought them. I think the
Shens are made at least as good if not better than most Romanian Basses and the
New Standard line is another good option at over 4k.
