Pre-tensioned. Velvety drone. Easy trumpets. Thick vocals. Easy overblowns. Excellent harmonic balance. My band uses one didge throughout our entire set as it deepens the drone/trance element of our sound. The instrument I play needs to be supportive in every way that I want to play. This didgeridoo could easily step in to be my bands one and only didge. The mouthpiece is so soft and comfortable. The first bit of air pushed feels as though it just chained onto a moving train. It's as if the air column is pre-tensioned, waiting to spring into action. An absolute dream to play.
