Hello to all friends and lovers of rare and vintage musical electronic toys. This is the first museum of lost organs, damned keyboards, childish synthesizers, dusty voice transformers and singing calculators. Most of them are from the 70ies and 80ies.
The library currently has 112 of his organs and you can listen to a few on the audio page.
