The Korg Pandora PX4D Multi-Effect Processor brings together an entire world of effect and amp modulations with easy controls in an impossibly compact chassis that will have you playing with tones for hours. Sporting 200 total presets with 100 pre-programmed and 100 user-programmed, the star of the show here is a bank if 158 effect emulations from pickup simulators to realistic amp modeling. Easily readable thanks to the bright LCD display, this box of sound is designed to function equally well whether you're playing guitar or bass.
