Some musicians use the baritone as a replacement for bass instruments, while others make use of the baritone by adding new dimensions to their guitar tones. However you use it, bear in mind a few words gleaned from experience - be careful how you mix and match your guitar instruments.

Unless the music is superbly arranged, a bass, standard guitar, and baritone guitar all playing together can thicken things up as much as a milkshake. Used in the wrong context, this could cause more harm than good, but when a baritone is featured properly, there's absolutely nothing that will replace its tone.
