A tuner is the cheapest piece of gear that makes the biggest difference to how you sound. An out-of-tune guitar ruins a great performance, and it makes practice harder because your ear learns the wrong pitches. In this guide to the best guitar tuner options, we cover clip-on tuners for home and lessons, pedal tuners for the stage, a strobe tuner for setups and recording, and the free apps and browser tools that work in a pinch.
Clip-on vs pedal vs app tuners
Clip-on tuners attach to the headstock and read vibrations through the wood, so they work on acoustic and electric guitars, bass and ukulele with no cable. They are cheap, portable and ideal for beginners. Because they read vibration rather than sound, they cope with noisy rooms better than a phone app, though they can be knocked off and are less precise than the best pedal or strobe tuners.
Pedal tuners sit in your signal chain and mute your output while you tune, which is exactly what you want on stage. They are the most accurate and readable option for electric players, but they need power and a cable.
App and browser tuners use your phone or computer microphone. They are free and good enough for quiet rooms, but less reliable in noisy environments. Our free online tuner runs in your browser with no download, which is handy when you have forgotten your clip-on.

How to choose the best guitar tuner
Where you play. At home or in lessons, a clip-on is all you need. On stage with an electric guitar, a pedal tuner that mutes your signal is far more professional. For setups and recording sessions, a strobe tuner gives the precision to set intonation properly.
Your instrument. Most chromatic tuners handle guitar, bass and ukulele. Bass and low-tuned guitars track better on pedal tuners than on some clip-ons.
Power. Rechargeable clip-ons remove the hunt for coin cells. Pedal tuners need a power supply, and some can feed other pedals.
Bypass and buffers. If you use vintage fuzz, place it before a buffered tuner or choose a true bypass tuner.
Apps. Free apps such as GuitarTuna, Fender Tune and Peterson’s iStroboSoft are fine for quiet rooms. They are a good backup but are less reliable in loud spaces than a clip-on or pedal.
Tuning tips that matter more than the tuner
- Tune up to the note, not down. If you are sharp, drop below the pitch and come back up so the string settles against the tuning peg.
- Stretch new strings gently before tuning, or they will keep going flat. Our best guitar strings guide covers which sets hold pitch well.
- Retune after fitting a capo, or use a tuner with a capo mode. See our best capos roundup for models that pull strings sharp the least.
- Before a session, tune each string and check the intonation at the 12th fret. Our guide on how to tune a guitar for recording walks through it step by step.
FAQ
Are clip-on tuners accurate enough?
Yes, for everyday playing. Quality clip-ons are accurate to within a cent or so, which is finer than most people can hear. Strobe clip-ons like the Peterson StroboClip HD are accurate enough for professional setups.
Can I use a guitar tuner for bass and ukulele?
Most chromatic tuners work for bass, ukulele and other stringed instruments. Check that the tuner is chromatic or has an instrument mode for your instrument and, for bass, that it tracks low notes reliably.
Is a phone app as good as a real guitar tuner?
In a quiet room, a good app is close enough. In noisy rooms or on stage, the phone microphone picks up everything around you, so a clip-on or pedal tuner that reads the guitar directly is far more reliable.
