A tribute to the legend
Cherub is well-known for making high quality digital tuners and metronomes for decades. 

About 17 years ago, in 2005, Cherub released the first "clip-on" digital tuner WST-550G, which has been a hit to 
guitarists in the world. It was the very first time that we could tune the instruments in such a simple way. 

In 2022, we bring a new clip-on tuner WST-551C with Cherub's latest tuning technology to musicians.
It's a tribute to the legendary “Clip-on tuner”.

Easy to tune your instruments
The WST-551C is a compact, lightweight tuner that you can take anywhere. With its essential functions tailored 
specifically for tuning, it provides everything you need. Featuring just 2 buttons, it is incredibly 
user-friendly, making everyday tuning effortless.

Ultra clear, bright display
The WST-551C offers clear and bright LED units. With the intuitive light indications, you can easily identify 
the tuning for your instrument even in dimly lit locations.


High accuracy, adjustable reference pitch
Powered by a high-sensitivity piezo sensor and Cherub's latest tuning technology, the WST-551C delivers highly 
accurate and ultra-responsive tuning performance for musicians. And the reference pitch can be adjusted easily 
with one button.

Rechargeable Battery
WST-551C's battery can provide up to 150 minutes of continuous use. Recharging is quick and convenient thanks to 
the built-in USB-C charging port.

Markbass Cover Standard 104 HF

Markbass covers are made of the following materials:
Outer layer: Polyester 600D x 600D PVC
Padding material: PUR Foam 10 mm
Lining material: Nylon 190T PU

The lightness and portability of Markbass products is to some degree negated when 
heavy flight-cases are used. But when the musician transports his gear himself 
(in other words, outside of tour situations where the goods are transported by others), 
Markbass covers are a practical choice: lighter, less expensive, and still very protective.

- 1 metallophone 62.5 x 35 cm / 2.5 octave: F5~C8
- 1 practice drum pad (diameter: 19.5 cm)
- 1 tripod stand

A Tribute to Legends

The NAI-24 is a high-performance 2-in/4-out audio interface, designed for personal studios and professional-
grade audio production. Inspired by the legendary 76 compressor, it features a pure Class A discrete transistor 
microphone preamp with up to 71dB of gain and an easy-to-use pure analog compressor.

Utilizing a FET-type 76PRE compressor circuit, it delivers exceptional tonal quality through pure hardware 
design while allowing digital control for multiple preset modes. It supports a 32-bit/192kHz sampling rate 
and provides switchable audio interface modes to adapt to various production environments.

For optimal sound precision, the NAI-24 is equipped with high-quality AD/DA converters from AKM (Asahi Kasei 
Microdevices), ensuring professional-grade audio fidelity. Additionally, studio-grade audio transformers on the 
main output (1L/2R) provide a warm sound and electrical isolation to prevent ground loop interference.

With ultra-low latency of 3.17ms, the NAI-24 is designed for smooth and responsive performance. 
The user-friendly design includes independent 48V phantom power control, LINE IN switching, and HI-Z input, 
making it an ideal solution for musicians, streamers, and audio engineers.
