HumminGuru S-DUO PRO: A combined turntable maintenance tool

Happy Well International Enterprise Ltd., operating under the HumminGuru brand, offers a wide range of accessories designed to care for vinyl records and enhance their playback experience. Among their offerings is the HumminGuru S – DUO PRO, a universal ultrasonic stylus cleaner equipped with built-in scales for precise tracking force measurement. This second-generation device has been introduced with the PRO suffix in its name.

The HumminGuru S – DUO PRO combines two essential functions into a single device. Firstly, it utilizes ultrasonic technology to effectively clean the pickup stylus, removing any dirt or debris that may affect the sound quality. Additionally, it features electronic scales that allow users to accurately set the desired force at which the stylus makes contact with the record. These scales are an indispensable tool for vinyl enthusiasts seeking optimal performance.

It is important to note that the tracking force adjustment and control procedure should be performed even on turntables that come with pre-installed cartridges, commonly known as Plug & Play solutions. This ensures the best possible playback results. Furthermore, it is recommended to periodically repeat this procedure during the player's operation to maintain optimal performance.

A distinctive feature of the HumminGuru S-DUO PRO is that the electronic scales are supplemented with a tool for ultrasonic cleaning of the pickup stylus. Ultrasonic waves with a frequency of 110 kHz, combined with a special cleaning solution, remove any dirt from the stylus in just 20 seconds, helping to achieve the highest possible sound quality. A suitable pipette for applying drops of the solution is included in the delivery set.

The new generation of the HumminGuru S-DUO PRO tool differs from the previously available version in that it uses a rechargeable battery rather than batteries. It is also equipped with a charging station, which, in turn, can be connected to standard power supplies with a USB-C port. The charging station also allows you to store all the small parts included in the package, such as rubber feet, drying pads and a dropper for cleaning solution.

HumminGuru S – DUO PRO is already on sale at a recommended retail price of $139 . However, the indicated price does not include the cost of delivery of the new product from Hong Kong.
