Avante Bariton

This is a long scale baritone acoustic guitar, designed to be tuned to a low B with an extra long 27.75" scale length
You can play it just like an ordinary acoustic guitar and get huge low end sounds without a bassist. The scale is long enough to get good string tension to support the low pitch, but still feels comfortable for a guitarist. Such a cool instrument. Plus it looks amazing.

Designed by the legendary luthiers Michael Tobias & Joe Veillette, & discontinued for years, this model is probably best known for Ani DiFranco & Keller William's use of it.
