I saw a Kay pre war bass for sale online and its a five string. I never new five string bass went back so far. Whats the deal is it a low B or high C or something else all together. excuse my ignorance but I'm a elec. bass player who's getting instrested in Upright latley. Also for a guy like me who's been playing fender bass for thirty years should I go for a 3/4 bass? thanks Tony F.
