MonopriceChromatic Pedal Tuner - Black, Normal & True-Bypass Outputs, Easy to Tune Your Bass & Guitars - Stage Right Series

Pros:1. Very easy to read, large display.2. Very bright, but not blindingly bright.3. Perfect size. It won’t take up a lot of room, but also won’t tip over, when operating the foot switch.4. Very accurate. I checked it against a signal generator, calibrated to NIST standards. It was spot-on.5. It has rubber feet, to keep it from sliding around, if not used on a pedalboard.6. Operates from a 9V battery, or 9V power adapter.7. The entire enclosure is cast aluminum. (Except for battery cover and display, of course.)8. The display ‘locks on’ very fast, and ‘holds’ very well.9. It has three “flat tuning” settings, allowing you to tune down to ‘drop Db’.10. It has “true bypass” circuit design.Cons:1. If you want to place it flat against a pedalboard, using Velcro, you will have to remove three stick-on feet and the battery cover. You can also make a spacer, if you don’t want to remove the feet. (I used my laser cutter, to make a spacer.)2. The ‘concert pitch’ can only be adjusted from 436Hz to 445Hz. If you’re trying to align your cosmic chakras (432Hz), this isn’t your pedal and you probably should have paid attention in science class.I needed three, but I only bought one, due to mixed reviews on YouTube. One review said that the accuracy was “questionable”. Luckily, that isn’t the case. (See above.) I’ve had a few days to use it and I’m VERY happy with it. Now that I know that it’s accurate, easy to read and a pleasure to use, I will be ordering the other two, right away. You can buy tuners that are more expensive, but most of them will be hard to read, have ‘busy’ displays, and consume a lot of power. If you need ‘strobe tuner’ accuracy, buy a strobe tuner and keep it on your workbench. If you need a quick, accurate way to tune up between songs, this is the tuner you want. Can’t beat the price, either. I’ve been playing guitar for 38 years. I’ve owned many tuners and this one is among the best. I highly recommend this tuner! Rock on!!!

I was absolutely BLOWN AWAY by the quality of this pedal. It’s sized right for my pedalboard, and works well with my power supply. The design has bright colors that are easy to see from the stage. I cannot speak to sound quality or volume control as I have this pedal coming out of yThe “tuner pedal” output on my volume pedal, so it’s not in the signal train.

I'll start with the quirks because these could make or break this purchase for you even at the price of this:1) Activating the tuner induces a slight pop. It's not extremely loud and with enough effects and pedal it'd probably be buried in the other noise on stage, but it is audible like if you used this to mute yourself without messing with the instrument volume during a quiet time when you're not playing and want to be silent people might hear that, so take it into account. I will say it shouldn't be enough to distract from anything else going on and it really is quiet enough to be buried under any other sound in most situations.2) If you power this with battery, when the battery gets low it WILL suck gain away from your instrument. I figured this out during practice within the first week of owning and using this. I'd only had the included battery in and it hadn't even died yet, but as this had been the second time I'd used it long term, our sound guy noticed I was getting quieter and we'd already messed with the bass amp, and gain on the soundboard earlier and after pulling this out of the chain, I was back to being loud and he had to turn me down as when I played out everything vibrated. Basically, you NEED to power this thing with a 9v AC adapter and not a battery otherwise you'll regret it in the long term.Besides those quirks, this is actually a great pedal tuner. I will say it's not quite as accurate as a BOSS chromatic tuner or even my Fender clip-on chromatic tuner (when I compared they said I needed minor tweaks to some strings, but very minimal at all), however, you're talking about a difference that I, a violinist of 15 years who can tune 440hz A by ear alone can't hear the difference. I have only used this for my bass though, so maybe after I use this for my electric violin I'll have a different opinion, but I somewhat doubt that.It's also really responsive so I can use this to play along with and make sure as I'm practicing shifts and note positions I working towards as I'm learning the fretboard which is nice. I will say that anything that isn't an open string will almost always say you're flat or sharp (which on guitars isn't really possible), but it's great for figuring out the note of a specific fret as I'm learning.Overall, for the price, I don't think you can beat this pedal tuner. It does have true bypass as I use that feature for my in-ear monitors so we don't have to add the bass into the main mix, and it doesn't suck any tone as long as the battery isn't dying, so it's really a great little tuner. I don't think the pedal will hold up forever especially since there's already a click, but the metal construction means it'll probably last quite a while and for 1/3 of the price of a Boss tuner even if I had to replace these once every 5-10 years, I'd still be well under what a far more expensive tuner would cost. I do know I will eventually replace this as there are WAY high-quality options out there, but for someone just starting out and building up a basic pedalboard to play bass for my worship band before I start shelling out for the good stuff, this will get me started at a price point I can be comfortable with!

This tuner is well made. No concerns about the build quality. Good features. What stands out is the display, which is awesome. I've had several other big brand tuners that cost 4X - 6X as much as this one and this is the best display I've ever had on a tuner. It looks much better in person than the photos. It seems to be as accurate as anything else I've used. It reads quickly and doesn't bounce around. No issues reading my 5 string bass. I do not have the issue with the power supply plug not going in all the way as another reviewer stated and I also do not have any audible popping when engaging or disengaging. The only things I don't love are the rubber feet on the bottom making it difficult to put velcro on, but I managed to get enough contact to make it work without removing the feet. I also prefer the power supply plug on the top vs the side, but that's not a big deal either. This is a no Brainerd, it's unbelievable at this price point.

1st one didn't work. Would not turn on. Got replacement next day. Works perfectly. Big easy to see numbers. Quick response. Seems accurate compared to several other tuners. Would be a good buy at twice the price. Buy it.

The media could not be loaded. LCD screen stopped working and I’ve only had it for a little over a month. It’s not the battery either .
