Hey there! I've got the lowdown on the Yamaha PS 20 for you. This little guy's been making waves, thanks to its connection with Beach House. So, here's the deal – we put it through the wringer, and it came out looking pretty good. Sure, there are a few nicks and scratches, but overall, it's holding up well in the looks department. Good news, there's no major damage to the plastic casing.

Now, let's get into the nitty-gritty. It's a solid performer, covering everything from the orchestra to drum rhythms, bass arpeggio, and that built-in speaker system. But here's the catch – the first key (C) on the keyboard isn't playing ball. The rest are good to go, though a good cleaning might make them even better.

If you're curious about the specs, here they are for your viewing pleasure:

- Year of Manufacture: 1981

- Keyboard Configuration: Comprising 49 keys

- Polyphony Capability: Accommodating up to 10 simultaneous notes

- Pre-installed Sound Library (ROM): Comprising 10 distinct sounds and 8 rhythmic patterns
