Compact pedal tuner for guitar and bass guitar from Custom Shop series that provides an ultra-high +/- 0.1 cent precision, high sensitivity, great visibility, and sturdy construction. It features the first vertical 3D visual meter that offers large and easily visible note name indication and the distinct movement of brightly illuminated LEDs make the pitch difference and change instantly recognizable. Four meter display modes are provided to suit any playing style. In addition to the standard “Regular A mode,” it offers the “Strobe mode” or the “Half-strobe mode” in which the direction and speed of meter movement indicate the pitch change for easy visualization of even minute differences, as well as “Regular B mode” in which the meter rises by being stacked from bottom to top toward a reference line. Designed with the professional user in mind, the tuner offers extremely accurate tuning with a detection range of +/- 0.1 cents, a level of precision that is uncommon of pedal tuners. A broader range of pitch is also provided for the lower side of the meter (lower pitch) to an easier tuning experience. The true bypass design allows the input sound to be output with absolutely no change (when the tuner is off). In other words, the tuner circuit does not change, degrade, or colour your sound in any way. Since the input sound is completely muted when the tuner is on, this unit is ideal for use on stage. If a separately sold AC adaptor is used, the DC OUT jack can supply power to another effect unit. Since a dedicated power supply circuit is provided for DC OUT, it can provide stable and noiseless 9V 200 mA power. The high-efficiency, long-life design allows for approximately three times battery operation than the previous model. Operating life is approximately 15 hours when using zinc-carbon batteries, and approximately 30 hours when using alkaline batteries, providing the tuner the longest operating life of any pedal tuner. One zinc-carbon 9V battery is included for verifying operation. Dimensions: 68 x 113 x 45 mm. Weight: 286 g.
