Precise Tuning / Signal Correction

NUX HD PITCH Mini Pedal Tuner is a precise tuner with full colored LED screen and HD visuals. And it is perfect to be "first" in a signal chain. 

When you engage the pedal, it's an accurate tuner.
When you disengage the pedal, it's a signal buffer (in Buffer Bypass mode).
Bypass Mode
HD pitch mini pedal tuner offers selectable True Bypass and Buffer Bypass modes to deliver your signals according to your needs in the effect pedal chain.
 
Switching the Bypass Mode: Before you plug the power cable, hold the foot-switch then connect the power.  Note display screen will show the selected mode.
 
True Bypass mode: Pedal will MUTE the sound during the tuning.
 
Buffer Bypass mode: When tuning, you can switch between SILENT and AUDIO-ASSIST modes. And when you switch between Silent Mode and Audio-Assist, tuning screen displays the mode as shown below.


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
