ISET is a Chinese manufacturer of compact, budget-priced guitar effects pedals operated by Shenzhen Yishengtuo Technology Co., Ltd., based in Dongguan, Guangdong. The brand began by designing analog pedal circuits before expanding into digital effects, with a product team covering hardware, electronics, and software development. Most ISET units are housed in a small mini-pedal enclosure, and the line is widely available on Amazon and through the company's Reverb storefront.

The catalog spans common pedalboard categories at typically sub-$30 price points, including the Dumbler (a Dumble-style overdrive), the Grim heavy metal distortion, the AC Stage acoustic simulator, an Analog Flanger, an Analog Delay, a Digital Reverb with nine modes, and a Looper/Tuner Pro with multiple loop slots. The pedals use true bypass switching and standard 9V DC center-negative power.

ISET sits in the value-oriented corner of the pedal market alongside other small-format Chinese builders, and reviewers have noted hardware similarities to other mini-pedal lines from the same manufacturing region. The brand is generally positioned at hobbyists, beginners, and players looking to fill out a board with inexpensive utility effects rather than at the boutique segment.

ISET has 4 products cataloged on Equipboard, including Flanger Effects Pedals, Distortion Effects Pedals, and Multi Effects Pedals.
