10-Hole Blues Harmonica：JDR Assassin

An upgrade version of Ninja harmonica

JDR Assassin harmonica upgraded from the Ninja harmonica.

The details of the hole, cover plate, comb, blowing mouth radian, reeds plate manufacturing process, and other aspects have been comprehensively optimized, including over blow and Anti-squeaking treatments.

With Assassin, you no longer need to worry about whistling during technical notes, allowing your performance to reach new heights without limitations.

Updated ! Professional !

	Each reed has a whistling suppression sticker: Easily overblown without whistling during use.
	Each harmonica has been fine-tuned at the factory: Good overblowing and compression performance.

Comb	Maximizing the space inside the comb while maintaining the hole-to-hole distance allows the reeds to resonate more fully when vibrating. This design ensures that the reeds will not be blocked even when strong airflow passes through them.
spring plate	The reed plate production process has been improved to reduce the gap between the reed grooves and the reeds. This results in a more airtight harmonica that can be easily overblown.
cover plate	The cover's optimal curvature is designed based on ergonomic principles, taking into account the angle of force. This design ensures that players do not experience sore lip muscles during long playing sessions, significantly improving comfort while holding the harmonica.
sound processing	Applying a whistling suppression sticker to the reed increases damping in specific positions, effectively suppressing whistling during use. These inhibitors are highly adhesive and waterproof, ensuring that the harmonica's tone remains unaffected even after rinsing or ultrasonic washing.
