A. We stand behind and service all models of the Accu-Tuner here at Inventronics. We ask you send it to us insured and utilizing the following packaging guidelines. Find a box about a foot square, and use bubble wrap, peanuts, newspaper, or light packing material to take up the extra space. Set any accessories that you would like checked on the bottom followed by some packing material and then the Accu-Tuner closer to the top. By giving the Accu-Tuner some room for packing material, if there is some crushing of the box in transit the Accu-Tuner will still arrive safely.

Please send a note along with the Accu-Tuner to let us know how the unit is behaving and a phone number to contact you with any questions that we may have.

A. The Sanderson Accu-Tuner can store and reproduce the pitch settings for all pipes of even the largest pipe organ. Any temperament can be stored and the pitch level can be reset easily to track temperature changes in the organ. The Accu-Tuner can also tune to non-440 pitch (standard pitch is A-440). Harmonics or the fundamental pitch can be stored for any note, as well as the semitone below, and the fourth below for 10 2/3' stops. Celeste tunings are fast and easy since every pipe will have its pitch setting individually stored in the memory of the Accu-Tuner.

A. There are two methods: use a tuning stored in memory, a generic tuning, or create a custom FAC tuning. To create an FAC tuning you take three measurements of inharmonicity from the piano, and then the Accu-Tuner has enough information to create an 88-note tuning.

A. Yes, if the piano is 150 cents flat and you would like to tune it to 75 cents flat, store an offset of -75 cents, measure the stretch of the piano, calculate a tuning, then use the pitch raising program built into the Accu-Tuner to raise the piano to 75 cents flat, then on the second pass tune the piano to the 75 cent flat tuning you created.

A. Send Inventronics an email with the serial number of your Accu-Tuner IV and we will email back the latest operating system, and with the Piano Manager loaded on your computer you can update through a USB cable supplied with the Accu-Tuner IV.

A. Easy. Just contact us here using the form below or our phone number. We'll be more than happy to talk and help you figure out if the Accu-Tuner is the right solution for you.
