It is the wood that the rock greats have sworn by—swamp ash, in the form of their Fender Telecaster and Stratocaster guitars—for over 70 years. If you've ever listened to rock, you've probably heard a swamp ash, solid body guitar. But now, climate change is threatening the wood that helped build rock and roll.
In today's podcast, veteran guitarist Jim Campilongo takes us through the finer points of swamp ash and what it would mean to lose it. 
Bonus material: Here's Jim showing the difference between the sound of a solid body swamp ash guitar and a hollow body one. 
And a little about Jim latest project: Campilongo teams up with longtime collaborator Luca Benedetti on the album, " Two Guitars ." Check it out.
