I play double bass in several jazz ensembles, and in lieu of hauling my full-size upright around, I use an EUB -- thus I'm in search of a minimalist EUB that produces a decent sound. I own an NS CR4A and love it, but with stand it is hardly lightweight. I have owned/tried the Yamaha, Ibanez, Stagg, and others. The most portable instrument I've found is the ERGO, and I have one and love it, but Jesse has stopped making them. Are you aware of other very light full-scale EUBs, including ones made by boutique lines or individual luthiers? Many thanks, Paul
