Dear Anne Arthur-Dumas,

This appears to be an innate problem with Intellitouch tuners and is related to their sensitivity.

As the Intellitouch is sometimes incorrectly attached to the headstock of the guitar, rather than the correct placement on one's ear as described above, it picks up all vibration within the guitar. When switching on, it naturally picks up the innate vibration of the guitar when no string is being plucked, in other words background "white noise". This is always in the key of B# which is not a key installed on the guitar.

You will not find E# on an Intellitouch. This is, in fact the natural frequency of vibration of the universe and, as such, the ability to detect it is normally reserved for very expensive and sensitive astronomical instruments.

I would conclude, therefore, that your Intellitouch is functioning correctly.

Yours sincerely,

Dr. Guitar
