 Upcoming Project

To enjoy the best audio sound, proper and regular record cleaning becomes very essential, but keeping the stylus clean is just as important. Even though ultrasonic cleaning has proven to be a very effective and economical way to remove the contaminants with minimum risks of damage, applying ultrasonic technology in stylus cleaning is not a typical method and such products are rarely found in the existing market. The HumminGuru S-DUO, an ultrasonic cleaner specifically designed for turntable stylus, will define a new way to enhance the cleaning performance and overall experience.

HumminGuru S-DUO is a compact device that combines ultrasonic cleaning and digital pressure gauge in one place for the care of the turntable stylus. With smartly-designed 2-in-1 feature, it does both steps of stylus cleaning and downforce measuring in one go. The whole process is effortless and only takes the user less than a minute to complete. Its easy & quick operation, convenient use, storage, and portability make the cleaning experience seamless and pleasurable.

Ultrasonic Cleaning

HumminGuru S-DUO function

It is acknowledged that the stylus tip is very delicate and tiny. The HumminGuru S-DUO uses 110kHz of ultrasonic cleaning frequency which creates much smaller cavitation bubbles to remove dust, grime, and hardened dirt off the stylus tip thoroughly. The ultrasonic frequency of the cleaner is carefully selected and matched with an optimal amount of electrical power to avoid any damage and achieve effective cleaning in a safe manner. The process takes only 20 seconds by default with 3-4 drops of water (±0.3ml). 

Unlike those stylus cleaners that utilize motor vibration to clean the stylus with a short-hair brush pad, the HumminGuru S-DUO uses ultrasonic technology to better protect and extend the life of the stylus with no existence of abrasion. Cleaning the stylus in the ultrasonic bath with water requires zero physical contact and thus it is risk-free to the surface of the stylus.

For a stylus with a bonded diamond tip, it is 100% safe to clean without damaging the adhesive in the water. For users who would like to use any type of cleaning solution, please refer to the manufacturer of the stylus cartridge for advice.

Digital Pressure Gauge

On the other hand, setting the correct tracking force of the stylus is also an essential step for ensuring the playback result and the life of the valuable records and cartridge. The digital pressure gauge is cleverly incorporated into the HumminGuru S-DUO device that makes the setup more convenient, faster, and easier for the user. With the feature of a bi-directional LCD display, the user can simply flip the device around and measure the downforce right after ultrasonic cleaning. Moreover, there is an automatic zero clearing when powering up the device, and the display value can be zeroed at any time with a simple touch of the gauge icon button.
