Yamaha PSR 4500 Great model from the early 90s (golden music era). Amazing visual and working condition. The loudspeakers sound crisp, as good as a 35 years old speaker can be. Some of the highlights are - Dual 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, 100 rhythms and 100 different sounds. **please note the battery cover is missing** Comes with power supply In excellent fully working clean condition
