## Description

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

## 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 chain—simplifying 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 condition—from 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.
- JOYO QUALITY & AFTER-SALES CONFIDENCE: Backed by JOYO's decade-plus reputation for crafting innovative, budget-friendly gear. The Buffer Tune is part of the JF Series, built with upgraded precision components. Important: Powered by 9V DC adapter only (center negative, not included). Rated current: 160mA. Battery operation is not supported. For the quietest performance—especially when using the buffer circuit—use a regulated, isolated 9V power supply and avoid daisy-chaining with other pedals. Should any issues arise—especially unexpected noise, tuning instability, or power-related problems—our dedicated support team is ready to assist through your desertcart order page.

## Questions & Answers

**Q: Who is this JF-19 pedal suitable for?**
A: 1.Troubled by "muffled tone and lost high frequencies" caused by multiple pedals or long cables 2.Players wanting to simplify pedalboard with a single device that combines buffer and tune 3.Need frequent quick tuning while protecting tone

**Q: How to use this pedal quickly?**
A: 1.Guitar → JF-19 → Other effects → Amp 2.Simple setups (fewer than 3 pedals,cables under 2m): Turn on TRUE BYPASS, using only tuning 3.Complex setups (cables over 3m or 3+ pedals): Turn on BUFFER, which both tunes and compensates for high frequencies

**Q: How to troubleshoot if noise occurs?**
A: It is mostly caused by external factors (improper power supply, poor-quality cables, or ground loops in effects chain), rather than pedal itself Use dedicated power supply, shielded audio cables and properly plan the signal chain

**Q: What are the troubleshooting steps?**
A: 1.Use DC 9V power supply (center negative), plug it in firmly and check if the indicator light is on 2.Connection: Guitar → pedal → amplifier to test for signal output 3.Switch modes to check tone, press the footswitch to verify tuning display

**Q: How to achieve the best tuning accuracy during live performances?**
A: Switch to TRUE BYPASS mode when tuning between songs to eliminate ambient noise interference. Use BUFFER mode during songs to preserve tone over long cable runs.
