Easy installation without any permanent alterations.

What a great feeling it is, when you are sure that the instrument you are holding in your hands is 100% in tune! This gives you a safe feeling and speeds up your creativity.

So far, common tuners are either not handy, unattractive or were forgotten at home.

Fortunately, those problems belong to the past. With Shadow's chromatic tuner you own an onboard tuner which, after its easy and quick installation, becomes the heart of your instrument. Once installed the stylish tuner fits ergonomically in the soundhole of your instrument and assures perfect tuning at any time.

It does not require any permanent alterations to the instrument, thus is the perfect choice where a precision, high-quality tuner is needed for an instrument in which such alterations are undesirable. It works with a high-quality microphone and can be used independently from your pickup system. Automatic, comfortable, fast and especially invisible to the audience and unaffected by ambient noise.

With the Sonic Tuner you are able to tune your instrument more than 1,200 times without changing the batteries. The bright LEDs are absolutely accurate and don't shuttle like LEDs of other tuners do.

Sometimes the smallest things cause the biggest change.

  • The world's first soundhole tuner
  • Automatic, chromatic soundhole tuner for acoustic instruments
  • Precise tuning - even in noisy enviroments
  • Can't be lost or forgotten and always ready when you are
  • Ultra discret - only you know it is there

Too hard to turn on and off.

    Comments about Shadow Sonic Tuner For Acoustic Guitar Soundholes:

    I mounted the tuner at the edge of the sound hole as instructed. It turns on and off with a button that is about an inch in on the body of the tuner, so you have to use your thumb to reach it. In the process, the back of my hand pushes on the treble strings, which hurts my hand and also potentially changes the pitch of the strings that I have just tuned.

    Comments about Shadow Sonic Tuner For Acoustic Guitar Soundholes:

    This is a useful tool for quick tuneup adjustments and setting up for a session. I originally got this to use in my D 45 Martin Custom, but I just ended up using it on my Martin Junior for fun stuff. It deadens the ring of the Martin treble strings and drops the sustain of the bass strings, the sheets of velcro attaching seem to interfere with these properties. I am going to try to reduce the size of the velcro pads to see if a smaller attachment point would improve this, but a D 45 custom is not something to just play with, so I just popped it on my practice martin and away we went.

    Does the job

    Comments about Shadow Sonic Tuner For Acoustic Guitar Soundholes:

    Bracing around the sound hole can make installation tricky. I suggest you install it a little closer the the neck then center so that you can reach in with your thumb to turn on and off. Overall I'm happy and would purchase again but would consider a cheaper brand if the option were there.
    Not as easy to use as some digital tuners
    Works pretty reliably so far.
    The price is a bit high but worth the price if you're going to install it in a higher end guitar that you don't want to take the risk of scratching with a clip on.

    Shadow Soundhole Tuner is Great.

    By Brian Bessey

    from Chicagoland

    Comments about Shadow Sonic Tuner For Acoustic Guitar Soundholes:

    Love it.

    Want another for my other acoustic.
    I installed the Shadow soundhole tuner in just a few moments... I did have to loosed the B,E strings because I have large hand... but it was pretty sinple to do.

    It is out of the way...
    It did not influence the tone in any way...
    The LEDs are plenty bright enough...

    Gets my guitar in tune.
    It is a tech gadget... I think all of the guitar accessories are a bit pricey... more than they shoud be in this economy... but still very happy with the purchase.
