Description

The StageTuner ST-01 V2 combines all the aspects musicians look for in a chromatic pedal tuner. The large, bright but not dazzling 28-segment LED display is easy to read from several feet away. True bypass has no effect on your guitar’s tone, and the two outputs allow for either silent or audible tuning. The ST-01 V2’s reference frequency can be adjusted in 1 Hz increments from 432 to 445 Hz, and it has a tuning range from 27.5 Hz (A0) to 4.186 kHz (C8), accurate to 1 cent, all housed in a stylish, rugged metal enclosure.

The ST-01 V2 also sports a handy detuning function that lets you drop your tuning by 1, 2 or 3 semitones. All this makes the Stage Tuner ST-01 V2 the perfect companion you don’t want to miss on your pedalboard.

More info about this Product

Guitar Pedals

Guitar pedals are compact effects units that shape and enhance a guitar’s sound, sitting between the instrument and the amplifier. They include gain pedals like overdrive and distortion, modulation effects such as chorus and tremolo, time-based effects like delay and reverb, and essential utilities including tuners, compressors and loopers. Understanding basic things such as pedal type, signal order, power requirements and intended use helps players choose pedals that suit their style, setup and playing environment.

Tuner Pedals

A tuner pedal measures the input frequency and shows whether the played note is sharp, flat or in tune. Detection speed, display resolution and note range affect accuracy, especially for low tunings and extended-range instruments. Buffered or true-bypass switching changes the signal path, while mute, strobe display, reference-pitch calibration and alternate-tuning modes shape operation.
