JF-17 Extreme Metal

XVI is a practical and user-friendly Octave pedal. With independent Octave-up and Octave-down adjusting knobs, so you can adjust as you like. Moreover, it features MOD effects exquisitely designed by JOYO’s engineers, compared with similar products from the rivals, XVI offers much richer tone.

R-13 XVI

OYO JF-321 Bullet Metal Distortion - The Bullet metal will be the best friend of every metal guitar player.
The built in NOISE GATE function is great to make sure that there is no extra noise between the chords or single notes. Bring the Bullet Metal to your metal-fest and know that even when you are not using it, its true bypass design ensures that your guitar signal remains of the highest quality. The Noise Gate can be adjusted to tackle one of the more troublesome aspects of high gain metal playing,  the loud hiss and noise that comes with turning way up! The Joyo JF-321 Bullet Metal has that sweet noise gate to silence even the worse single coil noise (when you're not playing).

JF-31 Noise Gate

The GATE OF KAHN is a noise gate that utilizes VCA technology. A new approach to gating results in a  very quick response time. It responds very subtly to low input signals and therefore let’s your notes ring out naturally without cutting them off. Your original guitar sound gets preserved and the gate has very little influence on the actual sound. It acts as an invisible tool in the background that just cuts out the noise in between the notes without you even noticing that there ever was noise to begin with. The true Bypass makes sure the pedal becomes audibly invisible even when it is turned off.
