I tried and tried and tried to believe that 4-string basses are the only thing to use in a band, but that has been changing over the past half year for me. Last spring I took delivery on my custom built 6-string bass (32" scale, strung EADGCF). My plan was to only use it at home for solo bass noodling. Well, the bass has infected me and now I'm talking it to nearly all of my band practices. No, I don't NEED the extra strings, but every once in a while the opportunity presents itself where the extra strings are a serious benefit. Yes, I used to say 4 is all you need which is true, but now I realize that it goes beyond need. 6 strings equates to convenience. Actually, the freedom even extends beyond just me. In my three piece band, we are finding that I can use chords to fill out the sound when the guitarist plays a solo. I was even noodling around on the F string tonight at practice at the opening of one song and my friend the guitarist asked me to leave it in because he liked it. All I can say is, wow, this is really fun and I don't know why I didn't try it sooner.
