I used to have a 5 string . Unfortunately , I started gigging again,and had no proper time to master it. I wasn't too bad, but just never felt like I could use it in a band situation ,without sounding like les Dawson. I tried b-e-a-d on my steinberger , which is sturdy enough to take the pressure IMHO .
However, it doesn't feel right, and I can see myself getting another one , while offloading one of my 4 strings.The B string does sound great and make a difference IMHO .
