Some could argue the Xaphoon to be much like a Ukulele, in that its size deems it flawed by design. Yet there are many Ukulele players who are obviously not dissuaded by this, indeed myself occasionally included.
No, the Xaphoon is not flawed. It is however, very difficult to master. Oh, this is not to say the average novice will be unable to enjoy it, no, this is to say that the average professional Xaphoonist would have spent ten years perfecting it.
The difference between a Xaphoon and a Pocket Sax…? Bamboo die hards aside… depends how good you are.
First things first. I know what you are seeking. The sound of a Sax in your pocket. Yet you fear it to only raspberry, much like a Kazoo. This is a common misconception, seeded by poor examples of play, by amateurs trying too hard, as if to make a baby iron a suit.
