Korg (ToneWorks series) · Electronics > Musical Instruments & Gear > Guitar Effects Pedals
Era / Decade
Early 2000s (introduced approx. 2003). Identification clues: Compact digital interface, silver plastic housing, and LCD screen technology common to this era's pocket multi-effects processors.
Material
Molded plastic chassis with metallic silver finish; rubberized control buttons; internal digital circuitry. The PX4 model has a higher build quality relative to the later 'Mini' versions but remains primarily plastic-based.
Condition
Good. Visible cosmetic wear including light scratches on the screen and housing, surface dirt, and minor corner scuffs. Functional status is unknown; value assumes unit is fully operational with a clean battery compartment (no corrosion).
Demand Level
Moderate. There is a dedicated niche for 'vintage' digital modeling gear, particularly for musicians who prefer the simple interface of the older Pandora units over smartphone-based apps.
