@kissing and ingrate- will the electric uke sound good eventhough i don't use amps to play it silently?
That's an extremely pertinent question! They do not sound like a "real" 'ukulele. In my experience, they have more sustain, and a more "electric guitar" sound.
Some electrics (Eleuke, et. al.) have a built-in pre-amp, so you can plug your earbuds directly into them. Some (RISA, et. al.) have no built-in amplification, so you need something external, such as an amPlug to use earbuds.
If you want amplification and authentic 'uke sound, get an electric-acoustic.
