This is simply great. It's fun, easy to do and the instruction is clear and methodical, meaning he
goes over in great detail, multiple times. I've done this as a one-off, only (COVID and all), but
it's a fooler to the layman. Easily adjusted to your performance style, and the gimmick you learn
to construct can be done in a different way (different foundation) easily. I recommend this DL,
well worth the cost of admission.
