The Korg Toneworks Pandora PX4D is the successor to the widely acclaimed Korg Pandora PX4 personal multi-effects processor.

The Korg Toneworks Pandora PX4D packs both guitar and bass functionality into a single unit (a first in the history of the Pandora series). The PX4D contains a total of 158 effect types ranging from realistic amp sounds, including high-quality cabinets, to sophisticated effects and lets you use up to seven effects simultaneously. One special Korg Toneworks Pandora PX4D function is a Bass Canceller that removes the sound of the bass from an external audio source.

The Korg PX4D 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.

The one hundred built-in rhythm patterns of the Korg PX4D cover a broad range of styles that include rock, jazz, funk, blues and dance music. The PCM sounds used in these patterns produce accompaniments 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. You can also make Chain Pattern settings to combine up to sixteen different rhythm patterns.

The Korg PX4D offers 25 amp types along with 23 cabinet effects newly created especially for the PX4D. You even have the ability to combine a guitar amp with a bass cabinet if you choose. In addition to standards such as compressor and wah, there are numerous modeling effects. Pickup modeling transforms the sound of a single-coil pickup into that of a humbucking pickup (or vice versa), a guitar (bass) synth that lets you play synth sounds, an intelligent pitch shifter that automatically harmonizes with your playing, a talk effect that produces the impression that your guitar is speaking, a slow attack effect that creates violin-type swells, a feedback effect that allows feedback playing techniques that are normally possible only at high volumes, a rotary speaker that changes speed in response to your picking or fingering dynamics, a fretless bass effect that simulates the distinctive sound of a fretless bass, and more are ready for your use.

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.

You can also connect a CD player or another external audio source to the Korg PX4D 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. The Korg PX4D also contains a Bass Canceller function that erases the bass sound from an external audio source so that you can play and hear your bass along with the song.
