Hi everyone, first post here, complete novice with electronics and instruments. Been trying to find a device vaguely similar to a theremin that plays a steady note, and has knobs to adjust frequency, pitch, and volume.
I dont even know what one would call this but I'm looking for a box like this that I could hook up to speakers, preferably without an amp between them.

heres hoping!

Music From Outer Space's Weird Sound Generator ( seems like it could be the ticket. It would be more fun than a signal generator. You can build them yourself or purchase kits or buy a complete one. I don't believe they have a volume knob but that is easily remedied. People have devices similar to this on ebay all the time.

Thanks for the help, yes this seems along the lines of what I want, something that can generate sound waves from low to high frequency with output plugs, I was looking at audio signal generators but they seem to be in the hundreds of dollars, and the weird sound generator looks like a lot of fun but a bit excessive for what I want (not to say i wont impulse buy it in the next hour) but if anyone knows of a simple product that meets my needs I would be a very happy person who still only has half an idea what he is talking about. :)
thanks everyone
