Apparently I do! I have a 5ver actually 2 at the moment, though most material I play don't go below low E! The scattered song I use low D, though I have a D tuner on my jazz for such occasions I find that when I play a 5ver I could very easily have gotten by with the 4, and the B string is used more as a ramp than anything! I actually force myself to hit notes on that B just to justify having the darn things!!!
