Joyo JF18R Power Tune Guitar Pedal Tuner & Multi-Output Power Supply

The Joyo JF18R Power Tune combines two essential tools for guitarists into one compact, convenient unit: a True Bypass pedal tuner and a multi-output power supply. Designed to save pedalboard space and eliminate noise, it ensures your effects and signal chain perform at their best.

The power section features filtered, low-noise outputs with short-circuit and over-current protection. Six outputs provide 100mA for standard analogue pedals, while two additional 500mA outputs handle even the most demanding digital effects units. Crosstalk and hum are minimized, and the switching adapter stays cool during use. The package includes 8 DC power cables and 2 polarity-reversing cables for versatile connectivity.

The tuner section features a large, easy-to-read LED display and a rapid chromatic tuning algorithm for fast, accurate note detection on both guitar and bass. With a True Bypass circuit, the tuner can be used independently without affecting your signal.

This all-in-one solution delivers reliability, precision, and convenience for every guitarist.
