JOYO Buffer & Tuner Guitar Pedal, ±1 Cent Accuracy with LED Display & Analog Buffer Circuit, DC Output, True Bypass (Buffer Tune JF-19)

Features

• 1 CENT HIGH-PRECISION TUNING & BRIGHT LED DISPLAY: The Buffer Tune delivers precise tuning accuracy down to 1 cent. It features a large, bright real-time LED display that remains clearly visible even on dim stages, supporting quick and accurate tune-ups between songs. Compatible with electric guitars, 7-string guitars and basses, it offers fast response and stable pitch tracking for daily rehearsal and live performance.
• BUILT-IN ANALOG BUFFER PRESERVE TONE THROUGH LONG CABLE RUNS: The dedicated analog buffer circuit prevents high-frequency loss and tone degradation caused by long cable runs and complex pedal chains. When activated, the buffer strengthens guitar's signal without coloring tone, ensuring sound reaches amp with the same clarity and presence as if you were plugged in directly. One player described the buffer "is good and my signal sounds nice again" after struggling with high-end roll-off from long cables. The independent Buffer switch lets you toggle between Buffer mode (for complex setups) and True Bypass mode (for simple setups), giving you complete control over your signal path.
• BUILT-IN DC POWER OUTPUT POWER YOUR ENTIRE BOARD: Unlike standard tuner pedals, the Buffer Tune features a dedicated 9V DC output jack that can power another pedal in your chainsimplifying your pedalboard layout and reducing cable clutter. The output current matches your input power supply, so a high-current adapter can distribute power to other pedal through the Buffer Tune. This unique feature makes the JF-19 an ideal centerpiece for compact, efficient pedalboard designs.
• BIG, BRIGHT LED DISPLAY JF SERIES DESIGN: The large, colorful LED screen provides excellent visibility in any lighting conditionfrom bright outdoor stages to dimly lit clubs. The display clearly shows note names and tuning accuracy at a glance. Encased in a rugged metal alloy chassis, the Buffer Tune features a compact footprint that fits neatly on any pedalboard. The smooth, responsive footswitch provides reliable activation for silent tuning. Note: for the most accurate tuning during live performances, switch to True Bypass mode to eliminate potential signal interference.
