Select one of three settings by double-tapping anywhere on the upper half of the screen: volume only, tuning only, or volume + tuning. Double-tap anywhere on the lower part of the screen while the tuner is shown to bring up the pitch menu. The tuner’s reference pitch can then be changed by single tapping any of the frequencies. The pedals are tuned to the usual 440 Hz, however, there are options for 432 Hz to 447 Hz. Simply press and hold the lock icon for three seconds to lock or unlock the touchscreen.
On your pedal rig, the VPJR Tuner can be utilized as a master or gain control. It may be used with practically any 9 to 18-volt power adaptor you may have laying around. With 9 to 18 volts of headroom (depending on the power source), the mono input port can handle both passive and active audio inputs, making it a perfect tuner pedal for both bass and guitar.
