Watch Gretchen Menn and Helen Ibe give the acoustic performances of a lifetime in the finale of the No Limits Challenge competition

When it first unveiled the offset SC design at NAMM two years ago, Martin wanted guitarists to re-think what was possible on an acoustic guitar. 

Featuring a bold cutaway that grants unprecedented upper fret access for an acoustic, the SC line – which was expanded with the unveiling of the SC-10E, SC-13E Special and SC-13E Special Burst in January – was a significant step for the storied company.

To celebrate the models, earlier this spring Martin launched – in partnership with Guitar World – the No Limits Challenge, an exciting competition where eight up-and-coming guitarists face off against one another, covering tunes one wouldn't normally associate with an acoustic using a Martin SC model. 

For the quarterfinal round, the eight competitors were split into four genres – funk/R&B, '80s rock, '90s rock and classic rock. Sophie Burrell, R.J. Ronquillo, Helen Ibe and Gretchen Menn advanced from there to the semifinal round, which featured two more genre-based face-offs.

From there, in turn, Ibe and Menn advanced to the much-anticipated final round.

For this grand finale matchup, the two guitarists truly brought their A-game. Menn wows with a serene acoustic instrumental called Venice, while Ibe shows off her impeccable compositional skills with a unique mashup of Classical Gas and Stevie Wonder's Superstition.

Who decides the winner, then? That distinction belongs to you, the reader! Take a look at the two performance videos, and cast your ballot for your favorite in the box at the bottom of the article. It's that simple.
