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

Very quiet, buffer works great, great price

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.

All I can say is this is the finest tuner I've ever used. I retired the whole pile of others.

I have the pedal in buffer mode, first pedal in my preamp chain. When trying to tune during a gig, the notes jump all over the place and I can’t reliably tune it when other ambient noises are present. I don’t understand why it won’t prioritize or only use the guitar signal plugged into it. But this is unusable in a live music setting and it is not fast at all. In fact it jumps all over the place between notes being flat and sharp.

I own several Joyo pedals and I've appreciated the sound and build quality from all of them. This tuner is no different. It's easy to use and works as intended. I plan to buy another for my bass.

Garbage. Works as a tuner, but kills guitars signal totally. On or off.

Display is big and bright, might be what you want, might not. I like the optional buffer, pedal is quiet either way, and I notice no signal degradation either way. The power out is nice. The size is weird though. Footprint is between a typical MXR-style box, and a Boss, maybe even longer than a Boss. Makes it just a little awkward to set right on my board. But, I did buy this for a secondary board, so it was a price based purchase. Biggest negative is that it seems to track much slower than my other tuners. Accurate, but slow Good value overall though.

Perfect!

Works ok (not super-fast at all) as a tuner for bass, no idea if it works as a buffer. It does introduce a high-pitched hum into my signal chain, which I haven't been able to troubleshoot. Not the cheapest tuning pedal out there, which might make the hum acceptable.

I needed a buffer to regain the high end roll off caused from the long cable I use. I saw this pedal was cheaper than some standalone buffers and it is a tuner which is always useful. The buffer is good and my signal sounds nice again, I highly recommend!

Display amplio y buena iluminación, precisión al afinar y un buffer funcional

Super promising pedal, and seeing that it was nearing the price point of TC electronic, I really wanted to give this a try as when Joyo gets it right, things are epic. Didn’t write lower because I don’t believe it’s helpful to base the stars on personal experience when you know the bigger picture. Unfortunately, within three hours of being on the board, and only being engaged a couple of times, the true bypass started to admit a high-pitched whistle. I’ve had this with The monomyth twice in a row, which was super irritating as I love that pedal. I believe that my only issue was was a company is that they must not have an optimised troubleshooting and testing process before making a release. I’m under The impression that the issue with the monomyth was confirmed to be a batch issue after a YouTube reviewer had the problem, but I’m not sure about this one. Either way, the most recent pedals being released are really innovative aesthetically and look to be pushing the price point up a notch. I love these petals and I am desperate for them to feel like a safe choice when I order. The monomyth problem I heard on a paid tour and that was super embarrassing.

Feels cheap. Also it never detected a note on my acoustic. Unusable. Returned
