The Pandora PX4D from Korg is a multi-effects processor designed specifically for both electric guitar and bass. Its comprehensive range of sounds includes vintage amps and a wide range of cabinets, as well as effects ranging from classic to distinctively unique.

In addition to standards such as compressor and wah, there are numerous realistic modeling effects that deliver a versatile range of tones. Pickup modeling transforms the sound of a single-coil pickup into that of a Humbucker pickup (or vice versa,) a guitar (bass) synthesizer that outputs synthesizer sounds, an intelligent pitch shifter that automatically harmonizes and a talk effect.

Up to thirty seconds of an audio source such as a CD, MD or MP3 file can be recorded and played back repeatedly at a slower speed without changing the pitch. This is a great way to learn complex or rapid passages by ear. The PX4A is a great choice not only for practicing, but for any situation that demands great guitar or bass sound, including recording and live performance.
