Hynotone is a guitar effects pedal brand operated as a sub-brand of Topping (Guangzhou TOPPING Electronics & Technology), a Chinese audio electronics manufacturer based in Guangzhou and better known in the hi-fi world for its DACs and headphone amplifiers. While Topping targets audiophile desktop gear, Hynotone was spun out to focus specifically on guitar-oriented stompboxes, leaning on the parent company's analog circuit design experience.

The lineup centers on JFET-based tone shaping and compact amp/cab solutions. Products include the JunctionDrive JFET boost pedal, the Ares distortion preamp (built around a 5-stage JFET circuit with a 3-band EQ aimed at metal and drop-tuned guitars), the Berserker dual-channel all-JFET preamp, the CabScreamer60 60-watt power amp pedal with presence and resonance controls and a balanced line out, and the CAB105, a passive 5-inch guitar speaker cabinet intended to pair with the power amp pedal.

Hynotone products are positioned at budget-to-midrange price points and sold through Topping's own store as well as third-party retailers including Guitar Center and Amazon. The brand is still a relatively new entrant in the pedal market and is most visible through pedal-enthusiast communities on Facebook and YouTube rather than through a large roster of signature artist endorsements.

Hynotone has 5 products cataloged on Equipboard, including Guitar Preamp Pedals, Guitar Power Amplifiers, and Guitar Amplifier Cabinets.
