Our hybrid models are made with a mahogany neck and bridge, with a carbon fiber body. What sets our wooden necks apart are the two carbon fiber stiffening rods that run alongside the truss rod. These help the neck be more resistant to warping and bending than an average wooden guitar. Our full carbon series takes wood out of the equation, with a carbon fiber composite neck, fretboard, and bridge on our carbon fiber body. This full carbon build is extremely damage resistant, nearly weather-proof, and won't ever bend, warp, or crack on you. They also have a better sound to them as well. This is due to the guitar being one uniform material, which allows for everything to vibrate at the same frequency. The composite bridge especially helps to bring a fuller, richer, and warmer tone. Which one is better for you may vary, however. Both are durable, but the full carbon series is much better if you plan on taking your KLOS in a hot or cold car for long periods of time, or on long outdoor trips. They are also best if you are looking for the best sound quality out of your KLOS! However, some players just like the feel of a wooden neck, or need a more affordable option, in which our hybrid series can still provide you the durability and longevity that KLOS is known for!
