Ultrasonic Stylus Cleaner
Enhance Stylus Frequency Response
The S-DUO uses 110kHz ultrasonic technology and water to eliminate particles/grime from the stylus tip. This advanced cleaning ensures precise tracking of high, mid, and low frequencies embedded in vinyl grooves, restoring the stylus’s ability to reproduce audio signals with lifelike clarity.
Contactless & Safe Cleaning
The S-DUO uses a water-based ultrasonic bath to clean without physical contact or alcohol. Designed for delicate bonded diamond-tip styluses, it eliminates residue while protecting adhesive bonds—ensuring thorough, damage-free cleaning every time.
Discover The Difference: Stylus Brush vs. Ultrasonic Stylus Cleaner
- Brushed (Left): Though seemingly clean, microscopic residue remains. These particles distort groove tracking, causing dull playback and skips.
- S-DUO (Right): 110kHz ultrasonic tech annihilates debris. Restores pristine 20Hz-20kHz response: crisp highs, rich mids, deep bass. Pure vinyl truth.
High-Precision Stylus Pressure Gauge (Non-Magnetic)
Non-Magnetic Alloy
S-DUO Pro eliminates magnetic interference for flawless signal measurement across MC/MM cartridges.
2 Decimal Accuracy
The pressure gauge is accurate to 0.001 grams with 2 decimal precision, while most others are accurate to 0.05 grams with chip adjustments.
Calibration-Ready
Includes a 5g calibration weight to verify accuracy and ensure consistent, reliable measurements over time.
Bi-Directional LCD Display
Flip the device 180° for instant downforce measurement post-cleaning. Perfectly complements the S-DUO ultrasonic cleaner for seamless workflow.

I am thoroughly impressed with the HumminGuru product line, which includes the NOVA ultrasonic record cleaner, S-DUO Pro ultrasonic stylus cleaner, and the Orbit static remover. Owning all of these products has been a game-changer for me, as they excel at enhancing sound quality without breaking the bank.

I'm genuinely amazed by the results! After giving my Ortofon Synergy stylus an ultrasonic clean with the S-DUO Pro for 20 seconds, the difference in sound quality was like night and day! The improvement in bass, composure, and overall ambiance was so noticeable—it felt like a complete upgrade. Great product, highly recommended.

A great product. Cleaned the build up on my stylus in 2-3 cycles leaving it pristine. Records immediately sounded better. Easy to use and does exactly what it is supposed to do.

Great unit, only issue is the screen and button use for ham handed persons. Very compact unit.

This review is for the S-DUO Pro Ultrasonic Stylus Cleaner for Record Needles + Stylus Pressure Gauge, delivered on time and in perfect condition from Amazon.This is much more than a digital tracking force scale (which every turntable owner should have). The scale is accurate and easy to use. Also has the option to easily clean your needle, the amount of literal “crud” that can accumulate over time can be more than a normal brush can handle. The difference in sound, as well as tracking is audible.While spendy, audiophiles will truly appreciate this device – Highly recommended!

Process from setup to cleaning took a few minutes in all. Definitely an easy process. The sound after the cleaning process was noticeably clearer. I also like the fact that its barely takes up any space. This thing does what it says!
