Legendary synthesizer CASIO VL-TONE VL1 - 1979 - Japan, in perfect aesthetic and functional condition, battery compartment free of corrosion, collectible piece.

This hybrid synthesizer and calculator, weighing less than half a kilo, has gained fame and fortune despite looking like a toy for children. Its ultra cheesy sounds have been discovered and immortalized in hit songs by artists like Trio for 'Da Da Da' and White Town. The Casio VL-1 or VL-Tone, as it is also called, has 29 calculator-style buttons, five pre-set patches and one user memory patch, built-in drum machine (waltz, swing, rock, samba, etc.), and a 100-note sequencer.
There is an LFO with vibrato and tremolo effects and an ADSR envelope.
The VL-1 is analog, tiny, and has a built-in speaker. The synthesizer itself is quite small, lightweight, and portable when powered by batteries.
Curiously, the simple cheesy sounds of VL-Tone have been used by Apollo 440, Devo, Talking Heads, The Cars, Dee-Lite, Sting, Stevie Wonder, Vince Clarke, Beastie Boys, The Human League, Trio, White Town, and Bill Nelson.
