Most Peterson tuners are available in a rackmount format.
Unfortunately, the Peterson factory does not sell the 490-ST in the rackmount configuration. Send us an e-mail if you are interested. In choosing to save money by using these tuners, you will have to sacrifice the convenience of having all of the offsets pre-programmed into the tuner's memory. Then you can press the UP or DOWN arrows on the tuner to adjust the tuner's calibration in 1-cent increments as you select each note.
