You can take it wherever you have a gig because it won’t demand much space in the guitar bag.

This Snark model is the newly improved piece of the lauded SN-2 tuner. Its processor is fast, and it features a high-definition screen that’s easier for the user to read. It is also endowed with lasting battery life. All of these comes with the portable and inexpensive clip-on tuner, having great value.

Its ease of usage is next to none; by simply clipping it on the acoustic guitar headstock and playing a string, the digital display will alert you to either tune-up or tune down the string. The clip is firm, and it helps the tuner rotate 360 degrees for an easy view from any angle.

A valuable and multi-tuning instrument effective for acoustic guitar with pickups.

+ Solid construction

+ Inexpensive

+ Accurate LED inbuilt reference tunes

It only works with acoustic guitars having a pickup

 

Another top-notch tuner from one of the famous brands, known for quality and value. Behringer TU300 is a chromatic tuner for all acoustic guitar players. It is solid and affordable and even suitable for beginners as well as professionals.

Since this pedal tuner is built only for acoustic guitars with a pickup, your guitar needs to be plugged into the device for it to function. Some users may like this option, but it is a limitation. To start using this tuner, apply pressure on the pedal by pressing it down to engage it. Once you strum a string, the chromatic tuner will find the sound pitch with a led indicator that changes color when you go from a sharp note to a flat.

It comes with seven different tuning modes: 3 for bass, 1 for chromatic, and 3 for the guitar. These seven modes are useful for players who want advanced features in their tuner. There’s also a bypass or mute switch responsible for silencing the audio so your audience won’t be aware that you’re tuning the guitar.

Lastly, every element of construction is rugged for heavy-duty usage and prevent wear and tear. You can power the pedal by a power supply or a 9V battery. If you prefer the power supply option, you’ll have to part with extra cash because it doesn’t come with the tuner.

This version of Boss chromatic tuner is a handheld gear having a meter display that’s responsive as you strum your guitar strings. One major talking point of this tuner is the jack that connects an acoustic guitar to a pickup and mic. This feature is meant guitars without pickups. This is one reason why a tuner like this is ideal for both acoustic and electric guitar tuning.

It is accurate, precise, and capable of lasting the user for years without faults. Some users testified that they’ve been using this tuner for over ten years. It is quite costly than an average portable tuner but is versatile, reliable, and the brand can be trusted.

A pair of shuttle switches are available on the sides, and their function is to switch in-between different modes. This makes this gear operation easier with one hand; if you’re good at multi-tasking, you can be hitting a chord on the guitar while operating the tuner.

Additionally, its usual tuning range is between AN (27.50 Hz) and  C8 (4185 Hz). Its battery life is not too impressive, with about 14 hours for a  CR2032. You’ll need another pair, and that may set you back around 1 or 2 dollars.

Not the right tuner for recording

TC ELECTRONIC POLYTUNE 3

A tuner with in-built Analog BONAFIDE BUFFER that preserves your tune for any recording or live performance.

+ Bonafide buffered bypass

+ Three tuning modes

+ Accurate

Inaccurate polyphonic tuning mode

A classic tuner of this nature from TC Electronics is a top innovation priced within an expected range. It is robust but won’t take much space in the pedalboard. Since you’ll be stepping on it, the size won’t be a concern after all. 

This tuner is a next-level gear that provides multi-tuning modes that include chromatic, strobe, polyphonic. All these are complemented with an onboard BONAFIDE BUFFER that maintains the tone over extended cable runs on the pedalboard. The LED display is an upgrade for better tuning accuracy.

You can get a full reading by strumming one or all six strings. This is the principle upon which it is being operated. It is most suitable for acoustic-electric guitars since you’ll need cables for it to function. The improved innovation has an analog circuit and retina display while it offers clarity and precision. Regardless of what mode you switch to, your tune remains perfect.

This powerful tuner can recall your preferred tuning, which means you don’t have to start setting pitch references and tuning modes again. The tuning magnet is responsible for its tuning precision.

The BonaFide buffer helps balance your impedance input without lousiness to avoid high-frequency roll-off, inconsistency from another pedal, and harmonic distortion.

DONNER DT-1

An heavy-duty tuner with bright LCD and affordable, but can’t be powered with battery.

+ Quite affordable

+ Built for heavy-duty purpose

+ Bright LCD

Batteries can’t power it

If you prefer a smaller tuner option that’s affordable and offers value to your music, Donner DT-1 is a perfect choice. It comes in a mini-pedal fashion and has some basic features as well as specs. This tuner is the definition of simple, accurate, and compact gear. It isn’t a main effect pedal type that will consume space in the pedalboard. 

Its user interface is a friendly type made up of three elements: a half-step indicator, footswitch, and an LCD. Another good thing to note in this tuner is the true bypass. There’s no need to worry about signal bleeding or other nuisances. 

Talking about the precision, you have a 1-cent error margin in this tuner, which is acceptable for gear like this. Its bargain cost is lesser than its value. A 9 volt DC power supply also powers it, but it won’t work on batteries. If you don’t fancy a clip-on tuner, this pedal format tuner is one for you.


Criteria used for evaluation

Display

One critical factor attached to viewing what the tuner is indicating legibility. A needle-based meter is used in many tuners to indicate your closeness to the pitch when you adjust the string tension. Other tuner models use LCD with graphics or LED light arrays that change from red to green when the strings reach the right pitch.

Most displays use various colors to indicate a sharp or flat pitch and also indicates the tuned string. Advanced tuners make use of strobe technology to indicate a real-time relative pitch. These tuners are built primarily for instrument technicians and sound engineers. 

You should take into consideration the stage lighting where you’ll do your tuning. Therefore, your ideal tuner must be brighter with large displays as it will be useful on stages with dim lights and where there’s too much sunlight.

Tuning modes

Many digital tuners come with optional tuning modes that match instruments like a 7-string and bass guitars. Some models support drop tunings, which are based on specific keys, instead of a standard reference. If you own a capo, for example, find a tuner that supports capo tunings. Versatile guitar tuners enable you to switch to different and tempered scales.

Bypass

Pedal tuners with bypass feature won’t color the signal output sent to the amplifier. Silent tuning bypasses the signal output to the sound system, thereby allowing your tuner to only display the tune’s visuals.

Auto pitch detection

High-quality tuners will automatically find out the played tone by showing its relation to the right pitch. Models of lesser standards require you to set the right pitch for individual strings, which can be tasking at times.

Mics and speakers

Tuners with an in-built mic can detect an instrument’s tuning naturally. They are useful for tuning different instruments. The ones with in-built amps and speakers can generate sounds that will develop your ears to pick the right intonation.

Frequently Asked Question

With the exemption of electro-acoustic guitars, it is evident that acoustic guitars don’t use a cord or come with one. These acoustic guitars can be tuned by ear or if you’re close to a computer with a microphone in hand. Even with these methods, it is hard to find the right pitch.

This is why you need a tuner, either a clip-on tuner or other types, especially if you’re learning the guitar. Playing off-key often can become part of you and is a bad habit. You can find it hard to recognize what a proper tune sounds like if you continue learning without a tuner. Tuners are handy and portable for any road trip or recording session.

You need a tuner to help you find the right pitch easily and become part of you so that when you find yourself in no man’s land, you can easily find the right tune without too many trials. Above all, you can only become a great player if you practice with sound equipment and keep yourself updated on the latest innovation to improve your sound.
