The playing brief
For bass players seeking a purpose-built acoustic instrument. The archive includes five- and six-string builds, smaller and extra-large bodies, and an eight-string octave bass with paired courses.
The string count and tuning establish the design brief. A five-string bass and an eight-string octave bass are different musical arrangements, not just different neck widths.
No. 634 has a small body with a 32-34-inch multiscale layout. Concorde No. 708 uses an extra-large bass body and the same documented scale range. Body size and scale are separate decisions.
