This is a great and affordable Pedal Tuner with true bypass, unlike the Boss TU3. This means your tone will not be affected when the tuner is off. When the tuner is engaged, the output signal is muted.
Its Chromatic tuning mode allows a wide range of tuning options. The LED display gives you a clearer tuning view. It has Flat tuning and A4 range. It's True Bypass Circuitry to allow you to quickly switch the signal in and out without latency or loss of tone.
It has a bonus feature that if no signal is present for 5 minutes, it will shut-off automatically.
