Frequently Asked Questions
The 684-4G features a more conical body design from the tuning slide onwards, offering a warmer, more projecting sound compared to the 686-4B's more cylindrical bore.
While well-made, the 684-4G’s size and weight, along with its more advanced design, make it better suited for intermediate to advanced players.
The included mouthpiece is a solid, general-purpose option, but serious players will likely want to experiment with others to truly dial in their ideal tone.
