NUX HD Pitch Mini Pedal Tuner

The 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 engage the pedal, it’s an accurate tuner. When disengage the pedal, it’s a signal buffer (in Buffer Bypass mode).

Tuner Overview
This Mini-Pedal Tuner is a whole new breed, created and developed with NUX’s latest technology yielding an ultra-fast response time, and unmatched precision tuning. It has 2 bright LED screens that display: notes, tuning, calibration, and bypass mode.

Tuning Visual 1 Arrow Mode
Tune 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.

Tuning Visual 2 Strobe Mode
Tune instrument until the LED indicator stops running. The LED indicators will be running from “right to left” if the pitch is SHARP, and “left to right” if the pitch is FLAT.

Bypass Mode
HD pitch mini pedal tuner offers selectable True Bypass and Buffer Bypass modes to deliver signals according to needs in the effect pedal chain.

Switching the Bypass Mode: Before 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, can switch between SILENT and AUDIO-ASSIST modes. And when switch between Silent Mode and Audio-Assist, tuning screen displays the mode as shown below.

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, 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 to avoid some true bypass circumstances and guitar signal will reach the end of 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 connected with many pedals OR with long cables, and with tone sucking pedals, 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 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 they combine the tuner and the buffer into a mini size to save 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.
