This is the toy I wish I got for Christmas, 1972!!!
Its funny, when you play with it you soon realise the relationship between the shape of the little pieces and the sound they make as its based on the envelope.. except the one that records sound of course… And here it is in use, in the dark:
I picked up one of these Zounds Zizzle from ebay a while back & I’ve had lots of fun with it (put the tempo on lowest possible, turn up the echo, dont use the spiky dumb drum loop module) but the most fun is watching my nieces & nephews interact with it! Actually the same goes for my Kaossilator, although it has some more serious musical uses….
