Yes it could, although it would depend on how you transfer the signal and the strength of the speakers themselves. I use a USB interface for my guitar through software designed to pick up the signal and it plays through my 400W speakers. Though I have a decent 5.1 system, it is not necessarily required if you use the guitar in this way, the software can manage the output and the speakers only play the sound.
it is a guitar that uses electricity to make the amplifier work, si they decided to call it the "electric guitar"
it depends on the type of guitar you got bass or electric, any amp will work for electric guitar but not all amps work with electric bass.
cool
No they won't work acoustically.
wear only the guitar and dance
No, a cabinet is just a speaker (or collection of speakers). A speaker needs to be amplified to produce sound. The same is true with headphones; they won't work plugged directly into an electric guitar or bass.
yes
plug them in
The brand of computer speakers you would buy for your small business would depend on what type of computer you are running and what you need your speakers to do. www.testfreaks.com/pc-speakers/ will give you a comparison to work from.
Hm.. they should.. but im not so sure. my sisters electric guitar amp works with my violin.
No, the plug will fit
No, computer speakers are universal and will work with your computers current software and sound card.
