The True Strobe or "Tru-Strobe" tuner is extremely accurate—+/- .1 cent—and sensitive.The purest input tones yield the best results. Here's how to achieve optimal tuning: Pluck the string with a light to moderate stroke. Strings will usually go slightly sharp right after the initial attack. Excessive or heavy plucking of the string will increase this effect. Give the string a second to "settle" before tuning. Pluck the string with the flesh of your thumb. This will yield less harmonic information for the tuner to analyze then using a pick. Turn the tone knob of the instrument down. This again will roll off high-end harmonic details and input a more fundamental tone. Lower the volume of the guitar 30% to 50%. This will usually yield less harmonic detail and input gain. While coarse tuning look at the entire display for movement. When the action of the LED's begin slowing to a halt, look at the leading LED for movement and continue to tune until the LED stops in place.
