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.

With that in mind, Martin recently 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 and Helen Ibe have already advanced to the semifinal round, which comprises two more genre-based face-offs. The winners of those, of course, will advance to the finals. 

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

This week, we've got two killer unplugged covers, by Jay Leonard J and Gretchen Menn.

This week is all about the '90s, and Menn and Jay Leonard J deliver with two impassioned versions of hits from alt-rock's heyday. 

Above, Menn tackles Alice in Chains' Man in the Box, while below, Jay Leonard J gets his funk on with a version of Red Hot Chili Peppers' Give It Away.

So, which is the better, more exciting and innovative cover? That's for you to decide. Be sure to check back next week, too, for the next quarterfinal matchup.
