Are there any permanent modifications to my guitar required for installing the2Micpro™ ?

None whatsoever.

Is the finish of my guitar protected from components of the2Micpro™ rubbing against the soundboard.

    The2Micpro™ has been designed in a manner in which it makes minimal contact with the guitar when installed, and wherever needed there is padding to make certain that the finish of a guitar is well protected.Please remember, the inventor of the2Micpro – Ken Donnell – has spent a lifetime as a professional luthier, and knows to protect and preserve fine musical instruments.

What about the Velcro attachment on the heel of the guitar. Is this safe to use?

    The heel cap is a non-acoustic component of every guitar. It merely covers the end grain of the heel, where the heel meets the sides (ribs) and back of the guitar. The heel cap is very durable, and always made of a dark hardwood, usually rosewood or ebony. While there is no experience of the adhesive used with the velcro attachments of the2Micpro™ causing any damage to the finish of a heel cap, repairing the finish on the heel cap is a simple procedure if ever needed.

Do I need to remove and re-install my the2Micpro every time it is used??

    No, the2Micpro™ has been designed so that it can remain on a guitar indefinitely. This is especially important for guitarist out on tour, as a classical or flamenco guitar with a the2Micpro™ installed will fit inside a standard hard shell case for transport without needing to remove the2Micpro™.

    There is no problem with removing and re-installing the2Micpro™ whenever needed or desired. But, when the2Micpro is re-installed, it may be necessary to re-adjust the mic on the long gooseneck to achieve the best possible sound quality.

Is the2Micpro™ a guitar pickup?

No, there is no real comparison between a pickup and the2Micpro, especially in regards to the sound quality which is produced. All guitar pickups, even “acoustic pickups”, generate a signal based on non-auditory sources…., the vibration of the strings, wood, or saddle.  The microphone elements of the2Micpro™ however, sense the movement of air… the same as our ear recognizes sound energy by sensing the movement of air. So, microphones, and especially The2Micpro™ reproduces the most natural sound quality possible…. the same sound as your guitar, only louder.

How does the 2Micpro™ record such natural sound with mics placed inside the guitar?

    The 2 mic elements of the2Micpro gooseneck are designed to be located in the two most acoustically active sections of the guitar…. In the soundhole just beneath the strings, and in the middle of the guitar body, approximately underneath the bridge.

    A guitar soundhole acts as a natural mixer for all of the frequencies produced by the instrument, and this mic location provides the most overall “balanced” sound for a guitar.

    The center of the soundboard is the next most active acoustic region of a guitar. But, there is so much variation of the vibrational patterns with guitar soundboards, that there is not a single specific location under the soundboard where every guitar can be best recorded and amplified. So, the longer gooseneck of the2Micpro permits a wide enough range of mic locations underneath the bridge so that every guitarist can experiment to find the “sweet spot” for the mic underneath the bridge that will best complement the mic in the soundhole, and complete the amplified sound of the guitar.

Why does the2Micpro™ have a longer gooseneck than the original the2Mic model?

The2Mic™ (original) was designed for easiest possible mounting through the soundhole, while also providing the ability to be easily moved from one guitar to another. For these two features, the2mic (original) is still the best choice of models in this product line. But touring musicians found it difficult to constantly remove and reinstall the2Mic™ (original) for every performance, and for this reason, the2Micpro™ was developed.  the2Micpro™ model can be left on a classical or flamenco guitar indefinitely… even when the guitar is placed in a case for travel. Touring musicians who play unique handmade instruments also sometimes found that the2Mic™ (original) reproduced certain “wolf tones” . These wolf tones usually appeared in approximately 5% of the guitars tested, and usually only when these guitars were played in larger venues and at significantly higher volume levels. These wolf tones could always be corrected with good EQ.  The more permanent mounting of the2Micpro allowed us to also use a longer gooseneck that could be more specific in where the mic on the end of the gooseneck is located inside the guitar. And such a wide range of possible mic locations offers the ability to eliminate such wolf tones via mic placement, rather than electronic EQ.

What is phantom power, and how do I use phantom power to operate the2Micpro™?

    The 2Micpro™ includes an EPS-2 power supply to operate the2Micpro™. The EPS-2 needs 9-48v phantom power to operate, usually from a device such as a PA mixer, acoustic amp, or mic pre-amp. These devices will produce phantom power between 9 – 48 v, and the EPS-2 can accept any of these ranges of phantom power. Almost all modern microphone equipment has a phantom power option.

    Phantom power automatically travels up the cable from the device to the mic where needed. Sometimes there is a switch that must be activated to “turn on” the phantom power on in the device . Phantom power is always transmitted through a “balanced mic line”, which usually comes from an XLR input (some modern gear uses ¼” TRS phone connectors, and/or XLR-TRS combo jacks).

What can I do if I have gear that does not provide phantom power, such as my guitar amp?

    If you have older amplification gear that does not produce phantom power, it is possible to use our alternate battery operated power supply… the EPS-1. But it is important to note that the sound quality when using our 2Mics with older amplification gear is often not as good as using modern digital PA equipment. This is especially true for electric guitar amps, which were designed to be used with magnetic pickups & electric guitars, not microphones.

Do “acoustic guitar amps” work better with the2Mic than electric guitar amps?

    Yes, “acoustic guitar amps” usually reproduce a much more natural acoustic sound than electric guitar amps. Acoustic guitar amps are also usually much less prone to feedback with the2Mic™ compared to electric guitar or bass amps. Many acoustic guitar amps also have XLR inputs and are able to produce phantom power. For the most part however, acoustic guitar amps are primarily designed to work best with piezo type pickups (not microphones such as the2Mic, so the electronics and chosen speakers are oriented towards using pickups, not microphones.

Will using a “Direct Box” help the sound quality with the2Micpro™.

    The short answer is – “No”. But, there may be exceptions. Direct boxes, like acoustic amps, are mostly designed to help improve the signal of a pickup so it will sound more natural. There are some stereo direct boxes which do have a side dedicated to a microphone signal, and can be useful for EQ, but overall, the performance of a direct box will be inferior to using a PA mixer, and especially a Digital Wireless Mixer.

I am hearing finger noise and string noise when I play using the2Micpro™, can these noises be reduced or eliminated?

If the mic in the “soundhole” is adjusted downward, to point more towards the guitar’s back, this will help to reduce or eliminate string and finger noise from being amplified. To make this adjustment, push the short gooseneck downward into the guitar body further away from the strings. This will push both the long gooseneck and the mic in the soundhole downward. Once the mic in the soundhole is properly positioned, the mic under the guitar bridge (at the end of the gooseneck) may also need to be re-positioned to it’s best location.

Do I always need to use a PA mixer when performing with the2Micpro™ ?

    Connecting into a PA mixer is most often the best choice for guitarists using the2Micpro™ along with the EPS-2. This is especially true for concert halls and venues having a high quality house PA system and a competent sound engineer to operate the PA mixer. A great alternative is for guitarists to bring their own powered speaker and/or digital wireless mixer to use as a stage monitor, and then send a signal out of the speaker to the PA mixer for the sound engineer to control the sound for the audience.

Is the2Micpro compatible with the new TourMic wireless™ system?

the2Micpro™ was designed with the TourMic wireless specifically in mind.  They are 100% compatible and together provide the excellent sound quality of the2Micpro™ in an unteathered form factor.
