HumminGuru S-DUO Pro
2-in-1 Ultrasonic Record Stylus Cleaner and Digital Pressure Gauge
Rechargeable | Portable | Effortless
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 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. HumminGuru S-DUO Pro, an ultrasonic cleaner specifically designed for record stylus, defines a new way to enhance the cleaning performance and overall experience.
HumminGuru S-DUO Pro is a compact and portable device that combines ultrasonic cleaning and a digital pressure gauge in one place for the care of the record stylus. With a smartly-designed 2-in-1 feature, it does both steps of stylus cleaning and vertical downforce measuring in one go. The entire process is effortless and takes users less than a minute to complete. Its easy and quick operation, along with its convenient use, storage, and portability, make the stylus cleaning experience seamless and pleasurable.
Ultrasonic Cleaning: Highly Effective and Safe
It is acknowledged that the stylus tip is very delicate and tiny. Unlike those stylus cleaners that utilize motor vibration to clean the stylus with a short-hair brush pad, HumminGuru S-DUO Pro 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 completely avoids physical contact and thus it is risk-free to the surface of the stylus.
HumminGuru S-DUO Pro utilizes 110kHz ultrasonic cleaning frequency, which creates much smaller cavitation bubbles that effectively remove dust, grime, and hardened dirt off the stylus tip. The ultrasonic frequency selection is carefully matched with an optimal amount of electrical power to ensure safe and efficient cleaning. It is 100% safe to clean a stylus with a bonded diamond tip, as the cleaning process does not damage the adhesive in the water.
By default, the ultrasonic cleaning process takes only 20 seconds, and requires the use of 3-4 drops of distilled water (±0.3ml). After the cleaning is complete, the provided dust-proof drying pads can be used to absorb any remaining water on the stylus tip and housing, ensuring that the stylus is ready for use. For users who prefer to use any type of cleaning solution in addition to water, it is advisable to consult the manufacturer of the stylus cartridge for specific advice and guidelines.
The combination of a short cleaning time, minimal water usage, and the use of drying pads makes the HumminGuru S-DUO Pro a safe, efficient, and quick tool for maintaining the cleanliness and performance of the record stylus.
Cleaning Effectiveness:
High Compatibility with Different Cartridges
HumminGuru S-DUO Pro is designed with high compatibility in mind, ensuring it can accommodate a wide range of cartridges. This is made possible through the inclusion of provided stylus rubber supports (3 types), which can be easily attached onto the water basin.
When preparing for ultrasonic cleaning, users will select the stylus rubber support that best fits their cartridge type. Insert it onto the water basin before filling up the basin with water and starting the ultrasonic cleaning mode.

Aluminum Digital Pressure Gauge: Precise & Reliable
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 Pro device that makes the setup more convenient, faster, and easier for users. With the feature of a bi-directional LCD display, users can simply flip the device around and measure the vertical downforce right after the ultrasonic cleaning.
Furthermore, it offers convenient features to ensure accurate measurements. Firstly, the scale will automatically reset to zero when switching from the ultrasonic cleaning mode, or users can simply touch the gauge icon button once to reset it to zero before each use. This ensures that the gauge starts from a consistent baseline for precise measurements.
Secondly, a 5g mass weight is included with the product to maintain accuracy. Users can periodically check the scale by placing the weight on it to verify that it measures the expected weight accurately. This allows for regular calibration and helps ensure precise weighing results.
Lastly, the calibration function further enhances accuracy by allowing users to calibrate the gauge if needed. This feature ensures that the readings remain accurate over time and can be adjusted if any discrepancies are detected.
Rechargeable
HumminGuru S-DUO Pro is equipped with a rechargeable feature, eliminating the need for disposable batteries. This not only offers convenience and cost-effectiveness but also contributes to sustainability by reducing waste. Users can easily recharge the device with a USB-C charging cable, ensuring continuous and reliable performance while minimizing environmental impact.
Built-in Storage for Organization
The addition of a built-in storage on the charging base is a thoughtful design. It provides a designated area for storing the rubber supports, the drying pads, the water dropper, ensuring that all small parts are organized and easily accessible whenever needed. Such feature greatly enhances convenience and efficiency during the cleaning process.
The Holistic Design
The dimensions of the device are 130 x 78.6 x 52 mm (5.1” x 3.1” x 2.04”). Without the charging base, the weight of the device is only 189 g (6.7 oz). It is compact, lightweight, and portable, allowing the user to easily carry around and requires a small space for storage.
