Invented and developed by designer Adam Wehsely-Swiczinsky and built by guitar-maker Andi Neubauer, the MADA caimes electric guitar features a unique semi-acoustic body composed of 3-dimensionally molded hemp pulp--no carving or milling involved. Because the body consists of only hemp fibers and no plastic, the resulting sound doesn't suffer from resonance gaps.

Fun fact: Willie Nelson will jam out on a MADA caimes at the "Ambassadors of Rock Tour" in honor of the Sustainable Biodiesel Alliance (go BioWillie!) at the Hard Rock Cafe New York at Times Square. Hopefully, he won't attempt to smoke it.
