$595 · Yamaha PSR 4500

Super rare top of the line flagship PSR from Yamaha in 1989. Architectural Synthesis System (DASS) tone generator, which effectively and realistically expresses instrument sounds through the combination of FM and AWM tone generators. With the ability to edit attack, decay, and other parameters, this keyboard is as functional as a synthesizer, and paved the way for the Yamaha Style keyboards to come. Feel free to Google Yamaha PSR-4500 or PSR-4600 for more videos they're the same model more or less. For fans of 1980's & 1990's "tablehooters" this unit is crazy. If you're in a retro band or just love to goof around with all the gizmos this keyboard/synth is loads of fun. Memory, record, and loads of sounds and settings to play along with or create your own. Comes with power bar, everything works and I'll throw in a keyboard stand. Only thing missing is the sheet music rack but that can be improvised.
