Seller's description

The Korg ToneWorks Pandora PX1 is a compact personal multi-effect processor designed for guitar practice, headphone playing and direct signal processing. Introduced in the mid-1990s, the original Pandora combines a broad selection of guitar effects with useful practice functions in a remarkably portable format. The PX1 offers 60 effect variations covering drive, tone shaping, modulation, delay, reverb and other processing, with 20 user programs for storing custom sounds. Its cabinet resonator provides speaker-cabinet simulation, making the unit suitable for headphone practice and direct connection to recording or audio equipment. An AUX input allows an external audio source to be connected for playing along with music. Additional features include a built-in chromatic tuner with a 27.5 Hz–2093 Hz detection range and a metronome adjustable from 40 to 208 BPM. Connections consist of a standard guitar input, stereo mini-jack AUX input and a stereo line/headphone output. The PX1 can operate from two AA alkaline batteries or a specified 9V DC adapter.
