Did a Good Job
on October 1, 2010
I had ordered the CA1 and CA-40 at the same time, but received the CA1 first, so I used it to tune our baby grand Wurlitzer (first time ever for me to tune a piano). The CA1 worked well indicating whether a string was solid on the note (green only LED) indicated on the display, or off the note (green and red LEDs). The great thing about the red LEDs on either side of the green is they tell you whether to tighten the pin more (when red LED to left of green is lit, i.e., string too loose) or loosen the pin some (when red LED to right of green is lit, i.e., string too tight). The first pass of tuning the piano took five and half hours, but to be fair, the piano was grossly in need of a tune. The CA1 did not pick up the higher octaves or the lower octaves but if you are patient and have "a good ear," you can tune, by ear, the octaves outside of the CA1's range. The CA-40 picks up more octaves than the CA1 (see my review) which speeds up the tuning process, but the octaves outside of the CA-40's range, though fewer, have to be tuned by ear, too. For the price difference, the CA-40 is a MUCH better buy for piano tuning.
Hint: Turn the CA1 or CA-40 upside down. If the string is too loose, the left LED will light but because you turned the tuner upside down, the LED will be to the right of the green LED... rightey tightey...leftey loosey...
