I have a Kremona 5-string, as well as an old Juzek 5-string (my main bass). The Kremona/Bulgarian basses are fully carved European basses sold by Bob Gollihur, and he is fantastic to deal with. Bob doesn't sell things that are sub-standard, and you will find pretty much everyone agrees that his is the best in customer service. My Kremona is a very good bass for the money, and I would recommend them. The tops of these basses are a bit thick, but I've heard that Bob had the factory in Bulgaria thin them down in later production models. The low B string takes some getting used to with the bow, but once you do get used to it, it is great. 5-strings are used a lot in European orchestras, but are rare in states. The neck is a bit larger than a standard 3/4 four string neck, but I have large hands and it doesn't bother me. Bob Gollihur offers a 7 day trial of these basses, in case you decide it's not for you.
