Product Description

Joyo JF19 BufferTune Pedal Tuner

The JF19 Buffer-Tune by Joyo provides accurate tuning and inbuilt features that make it ideal for the performing musician!

With super-fast digital algorithms allowing for responsive and fast tuning, the JF19 is also responsive for 7-string and extended range bass guitars, and the bright LED display means you can clearly see the displayed pitch in any conditions. Capable of powering an additional pedal with a 9V (centre-negative pin) power output, this means you’ll also save a valuable output on your power supply, and the small footprint won’t take up too much space on your board.

With inbuilt Buffer or True Bypass modes, this tuner is a valuable asset to any board. You can restore your signal and regain true tonal clarity after a long cable with the buffer mode engaged, and you can easily switch to true bypass to ensure other pedals (eg. some fuzz circuits) will play nicely with the JF19!

This pedal uses a standard center-negative pin 9V DC power supply, and requires 160mA minimum.

A solid, compact and reliable unit. Quick tuning with stable read out, and buffer/bypass options are both useful. Good service, delivery and price to match good quality.

It would be helpful, on pedals that have a display, to show pictures of the display on.
