Tune your instrument until the LED indicator at the center is lit. If the LED is on “left” the pitch is flat, LED is on “right” the pitch is sharp.

 

Besides audio-assist or silent tuning, HD PITCH Tuner’s Bypass mode selection is designed to be more efficient in any case of signal chain needs.
 
True Bypass, which is preferred the most, you can think of HD PITCH Tuner’s Input directly wired to the Output. When the pedal is in bypass mode, the guitar signal is routed to the next pedal without any interference.
 
But HD PITCH Tuner’s Buffer Bypass mode allows you to avoid some true bypass circumstances and your guitar signal will reach the end of your chain without any tone loss.

 

Altered Signal 

HD PITCH Tuner is perfect to be the first pedal in the chain.

Optional Buffer Bypass
Modern musicians are usually connecting more than 5 pedals on the pedalboard. According to the guitar, the pickup is high impedance, while you connected with many pedals OR with long cables, and with tone sucking pedals, you need to change the guitar signal from High Z (high impedance) to Low Z (low impedance) to solve Tone Loss situation (capacitance & inductance effect). And each pedal will carry the buffered signal which is very convenient if you already added some modulation effects into the signal path.  And the best position for the buffer is the first place. That’s also where the tuner placed, and we combine the tuner and the buffer into a mini size to save your pedalboard space.

Why Relay Buffer?
There are 3 typical buffer circuit designs: OP-AMP, BJT, and FET. The FET buffer circuit could generate Even Harmonics. This is quite similar to tube amplifiers, which almost every musician loves.
