Restoring a Yamaha PSS-20
I do some random playing on it at 4:15 I found this keyboard very cheap - 20dkr or the equivalent of 3 American bucks. Some might argue that this is what it's worth but I am not going to take sides in this. I can just say that the sound is so harsh that it causes some strange interference with the recording thingy.
The music is 'I knew you were trouble' that was a hit for Taylor Swift in 2012. I play it on a Bontempi keyboard.
