The Korg PX4A Guitar Effects Processor
A personal multi-effects processor for
electric-acoustic guitars! Since its introduction, the Pandora series has been

functionality and superb operability - all in an amazingly compact package. Now,

body tones. The PX4A is a great choice not only for practicing, but also for any
situation that demands a great sound, including recording and live
performances.

82 Effects Optimized for Acoustic
Sounds
The PX4A contains Body effects that model the resonances and
vibrational character of great acoustic guitars. Aspects such as guitar
construction and body size are modeled in painstaking detail for numerous
guitars, ranging from famous brands of the past through today's leading-edge
manufacturers. The direct sound from piezo pickups can tend to have a sterile
character, but the Korg PX4A's effects add the distinctive warmth of resonating
wood that is typical of an acoustic guitar, producing an extremely rich and
natural sound.
The effects of the PX4A extend beyond the
conventional boundaries of the electric-acoustic guitar and include models for
resonator guitar, a newly developed banjo, and nylon-string guitar - in other
words, you can play a wide variety of acoustic sounds using just a single
instrument. There are also mic' effects built in to the guitar effects processor
that simulate the sense of space and depth achieved by mic'ing an instrument.
With the Korg PX4A, mic'ing techniques that require years of experience and
knowledge can be utilized easily by anyone, delivering superbly rich acoustic
sound even when using a line output. There are also numerous other effects
included in the PX4A multi-effects processor, ranging from
standard sounds such as compressor, limiter, echo, delay, reverb, and chorus,
through distinctive effects such as a twelve-string effect that reproduces the
sound of a twelve-string guitar, and even a drone effect that simulates the
drone tones of ethnic instruments such as a tambura. With a virtually infinite
number of possibilities that still preserve your natural acoustic sound; the
PX4A is the ideal guitar effects processor for anything and everything from home
recording to live performances.
100 Programs to Select
The
PX4A provides 50 preset programs, covering a broad range of styles including
sounds of famous artists. You can also create and store 50 of your own user
programs.
Auto Notch Function Automatically
Detects the Feedback Point
The Korg PX4A's Notch effect helps
curtail the feedback or howling effect that can be a problem for amplified
acoustic instruments. There's also an Auto-Notch function that automatically
detects the frequency at which feedback is occurring, so you can perform with
the best acoustic sound at all times without being troubled by
feedback.
Amp-like Ease of
Operation
The user interface of the PX4A guitar effects processor is
knob-based for intuitive and easy use. Frequently used parameters, such as the
amp type, have their own independent dial, and the tone controls can be adjusted
just as easily as on a guitar or bass amp simply by turning the knobs. The value
dial makes it simple to adjust amp types and parameter values, and there is also
a TAP button that you can use to set delay times or the tempo of a rhythm
pattern.
100 Rhythm and Bass
Patterns
The one hundred rhythm patterns built in to this versatile
multi-effects processor cover a broad range of styles that include rock, jazz,
funk, blues and dance music. The PCM sounds used in these patterns produce
realistic accompaniments that are fun to play along with. There are also Bass
patterns that let you specify the key chord, so you can practice any style of
music while listening to a full rhythm and bass line. Since you can use the
effect programs at the same time as these bass patterns, it becomes a great way
to practice your picking, improve your rhythm and develop your sense of pitch.
In addition to bass patterns, you can also make Chain Pattern settings to
combine up to sixteen different rhythm patterns.
Built-in Phrase Trainer
You
can record up to 30 seconds of an audio source such as a CD, MD or MP3, and play
it back repeatedly (looped) at a slower speed without changing the pitch. This
is a great way to learn complex or rapid passages by ear, since you will be able
to hear the phrase slowly. You can also record your own phrase along with the
built-in rhythm and bass accompaniment, and then practice soloing over the top
of it.
Combine Your Playing with an External
Source
You can connect a CD player or another external audio source
to the PX4A guitar effects processor's AUX IN jack, and use the Key Transpose
function to change the pitch of the song upward or downward by as much as one
octave.
Semitransparent LCD for Superb
Visibility
The LCD that displays the names of effects and programs
is backlit so you can read it easily even on a dimly lit stage, and Icons
designed to represent numerous functions are immediately recognizable. The
display uses a semitransparent LCD so that characters and icons are lit up when
backlit, providing a distinctive appearance. The unit also comes with a strap
holder so that you can attach it directly to your instrument
strap.
