Featuring a bright LED screen for easy visibility and a unique DC output to power additional pedals, this compact, rugged pedal is designed for professional musicians seeking reliable performance and streamlined setups. ## Description Product description Troubled by tone loss? When multiple pedals are chained, high frequencies fade, making tone muffled and details lost. JF-19 Buffer efficiently compensates for this, restoring the guitar’s original tone. In fact, Buffer "compensates for tone loss" rather than "tone changes". It should be placed at the front of pedal chain. Detail Presentation for You Mode Switch If chain is simple, you can only enable "TRUE BYPASS" to use If cables are long or the number of pedals is β‰₯ 5, be sure to enable "BUFFER" Foot Switch Control Tuner/Buffer mode switching via footswitch (buffer remains active condition) 9V DC power output Equipped with a 9V DC power output interface, which can power other guitar pedals It simplifies the pedalboard layout and reduces cable clutter Power Supply Tip Power supply:DC 9V is NOT included in the package. Please select JOYO original power supply or other reliable brands to reduce noise and damage Mode switching based on devices How to play this JF-19 pedal well? Place the pedal at the very front of the signal chain (Guitar β†’ JF-19 β†’ other effects β†’ amplifier) to maximize the buffer's tone-protecting effect TRUE BYPASS mode: For setups with 3m or β‰₯ 3 pedals (high-frequency loss, muffled tone) – activates buffer compensation (restores high frequencies) + tuning to retain the guitar’s original tone Specification Vriety of guitar effect pedal styles JF-19 BUFFER TUNER R-28 DOUBLE THRUSTER R-31 PARA-VERB R-21 TORNADO JF-22 OXFORD SOUND R-26 MONOMYTH Who is this JF-19 pedal suitable for? 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 Who is this JF-19 pedal suitable for? 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 How to use this pedal quickly? 1.Guitar β†’ JF-19 β†’ Other effects β†’ 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 How to use this pedal quickly? 1.Guitar β†’ JF-19 β†’ Other effects β†’ 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 How to troubleshoot if noise occurs?

Its effect will be barely noticeable if your effect chain is simple (short cables, few pedals) 2.Functions: Precise tuning, buffer function and additional power supply output (simplifies pedal chain) 3.Tuning method: Features Β±1 cent accuracy and footswitch operation, which differs from headstock tuners or app tuners 4.If the user does not place it at the front of the effect chain or incorrectly switches between "TRUE BYPASS/Buffer" modes, the Buffer function will not work Review: Excellent Tuner with built in buffer - Very quiet, buffer works great, great price Review: It's a tuner - Works with bass well. It's a tuner for a good price. I don't gig out currently. Those days are behind me but I'd imagine it could stand up to a fair bit of abuse. ## Features - Tuning Mode--JOYO JF-19 BUFFER TUNER gives you fast, accurate tuning and a multi-functional tuning tool in a single unit with 1 cent accuracy.
