I know of the Bass Guitar, but are there any other styles of electric guitars? Can you purchase a guitar that you can adjust for a more classical sound? I was told once it's how you play the guitar.
Do you mean literally a classic type guitar - nylon string? Or are you just speaking of a standard electric Spanish with six metal strings tuned an octave higher than a bass? If you are looking for multiple tones check the Internet for modeling guitars. Line 6 make a number of them and they will emulate electric and acoustic guitars of varying types and tonalities. Some guitar synths, like the Roland VG systems, allow you to take an electric guitar and use it to play octave lower tones which sound very much like a real bass guitar.
