The Zap Zapper is a two-oscillator analog synthesizer, where one square wave is used to modulate the other.
It'll output some serious bass if you're into that.
Sound is activated by the silver button. Push it rhythmically for interrupted beeping textures.
Runs on a 9v battery, easily accessed through the back panel. It has a 1/4" output jack for connecting to guitar effects pedals, amplifiers, etc.
Handmade to order in Chicago, USA. Please allow 2-3 weeks for shipping.
Please get in touch with any questions, I'm happy to answer.
