This Guitar is a wonderful example of a bassy dreadnought guitar. No matter what you play the tone is balanced and full with the whole spectrum of frequencies you wanna have your body creating that melodic kind of natural "reverb" .
I've built in (don't hate me for that ;D) the pickup-system L.R.Baggs Anthem and its just incredible how extremely clear and natural the sound gets into the amp.
