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
When you engage the pedal, it's an accurate tuner.
When you disengage the pedal, it's a signal buffer (in Buffer Bypass
This Mini-Pedal Tuner is a whole new breed, created and developed
with our 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 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.
Tuning Visual 2 Strobe Mode
Tune your 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.
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.
Besides audio-assist or silent tuning, HD PITCH Tuner’s Bypass mode
selection is designed to be more efficient in any case of signal
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
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.
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.
And Relay Buffer has the same performance as FET buffer, we add the
optional buffer bypass function as FET buffer works for your guitar
