Since its introduction, the Pandora series has been acclaimed by guitarists and bassists for its high-quality sound, versatile functionality, and superb operability – all in an amazingly compact package. And now the PX4A join the series. The PX4A is designed specifically for electric-acoustic guitar, and can transform a piezo output (which has a tendency to be sterile-sounding) into many warm, deep, rich and natural acoustic guitar body tones. This unit is a great choice not only for practicing, but for any situation that demands a great sound, including recording and live performance.

Numerous built-in high-quality effects utilizing “REMS” modeling technology

The PX4A contains 82 effects optimized for acoustic sounds. This includes Body effects that model the resonances and vibrational character of great acoustic guitars. Aspects such as guitar construction and body size are also 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 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 to include models for resonator guitar, a newly developed banjo, and nylon-string guitar ­­– you can play a wide variety of acoustic sounds using just a single instrument. There are also mic' effects that simulate the sense of space and depth achieved by mic'ing an instrument. With the PX4A, mic'ing techniques that require years of experience and knowledge can be easily utilized by anyone, delivering superbly rich acoustic sound even when using a line output. There are also numerous other effects, ranging from standards 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 virtual infinity of possibilities that still preserve your natural acoustic sound, the PX4A is the ideal choice for anything from home recording to live performance.

The PX4A provides 100 programs (50 preset / 50 user)

The PX4A provides 50 preset programs, covering a broad range of styles, including sounds of famous artists. You can also create and store the same number of user programs.

The PX4A has an Auto Notch function that automatically detects the feedback point.

The PX4A's Notch effect is a helps to curtail the feedback (howling) 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 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 also be adjusted as easily as on a guitar or bass amp simply by turning the knobs. The value dial makes it a simple matter to adjust amp types and parameter values. There's also a TAP button that you can use to set delay times or the tempo of a rhythm pattern.

One hundred rhythm and bass patterns cover numerous styles with realistic PCM sound.

The one hundred built-in rhythm patterns 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 even 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 patterns, this is a great way to practice your picking, improve your rhythm or develop your sense of pitch. You can also make Chain Pattern settings to combine up to sixteen different rhythm patterns.

Phrase Trainer function helps you learn phrases by ear or practice soloing

You can record up to 30 seconds from 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'll be able to hear the phrase slowly. You can also record a phrase that you play yourself along with the built-in rhythm and bass accompaniment, and then practice soloing over the top of it.

Mix your own playing with the playback of an audio source

You can connect a CD player or another external audio source to the 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. Immediately recognizable icons represent numerous functions. 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.
