Re: Blog: "Play Nice" with the 8-string Guitar in Your Band
I play guitar, bass guitar and make plunky noises on Chapman Stick. Hence, I can see several sides to this discussion.
So far, most opinions have been "top down", so to speak. (Range extension from the guitarist's perspective. Intrusion from the bassist's standpoint.) I generally see the additional strings from a "bottom up" perspective.
Multi-string bassists such as Les Claypool are, effectively, covering bass and rhythm guitar functions within a band context. A multi-string guitar that covers the entire guitar/bass range only makes sense if the pitch difference between the melody and bass parts is going to be two or three octaves. (Just like playing a piano.)
At the time of this writing, I own one five string bass guitar. I have owned other five- and six-stringers in the past. For the most part, I find that I play better on a four string. Its "limited" pitch range forces me to be more creative.
EDIT - Being for the benefit of Mr. Jon. I agree that solo Chapman Stick recitals are not a bundle of laughs. I generally keep the bass register strings straight and process the **** out of my melody register strings. (Distortion, auto-filter, Roland VG99 modelled synth or guitar sounds.) Typically, the music produced is in the Crimson/Gabriel zone.
