From my adult owned collection is a RARE 1980 The Sound Gizmo by Fundimensions. It is in TESTED & WORKING condition. I had one of the which I received new as a present in 1980. That one went missing over the years, but I was able to find this one at a New York ToyCon in the mid 90’s. Excellent pre owned condition with a super clean battery compartment. Uses one 9 Volt battery (not included). They are becoming crazy hard to find in this nice of a condition. Fast USPS shipping from a pet and smoke free home.

In 1980 Fundimensions released a weird electronic toy called the Sound Gizmo. So what was the Sound Gizmo? Ready for this? It makes...sounds! To a kid barely into double digits that was obsessed with sci-fi, it was magic! You've got a slider on the right that lets you pick from 9 different sounds, three knobs to tweak the sound, and two buttons for duration.

The manual (not included here) gave you suggested control settings for typical sound use. But having 9 sounds with variable pitch and speed, who wants typical? This is really where the replay value kicks in. I remember when I was outside playing (it's a thing kids used to do a long time ago) it was sort of a imagination multi-tool useful in any situation.

Need a machine gun?

Use the Train sound and crank the speed up.

Need to break out (or in) somewhere?

Use the Siren and keep adjusting the pitch and speed until you hit the right frequency and you've got a sonic lockpick! And yes, that's totally a riff on the sonic screwdriver.

Need to really annoy someone?

Set it to Tone and crank the pitch all the way up.

It has been part of the Howard Stern Show for over 30 years where it was used in the days before soundboards to provide sound effects for the show. It has traveled all across America. It has been to England. And it has been heard by millions of listeners for decades.
