Re: Hmm.. Guitar sounds like crud unplugged, WOW plugged...??
Vocalists in most music genres need to use a microphone to sing with other instruments, and to perform at most venues they are likely to play. But do they use a mic at home to practise or sing along to the radio ? I bet they learn a lot more about their voice and how to use it when they sing 'unplugged'. I bet most singing teachers spend most of their time teaching without the use of microphones. I certainly wouldn't want to work with a vocalist who had never sung without a mic.
Not a good analogy. An amp really
is part of an electric guitar, and changes it's tone. Most amps these days have 3 or 4 EQ knobs, plus reverb, some have effects, you get tube breakup as the volume increases. The sound is modified by all that, not to mentions what happens to the signal from the PU's, magnets, pots, caps, and cord. All kinds of variables changing the acoustic sound to the electric sound. With a human voice, you usually don't have nearly as much going on when it's thru a mic. When a person's singing, using a mic lets the people in back hear; with an electric guitar, if it's not amplified, the people in front can't hear. Apples and oranges.
I also practice unplugged a lot, but it's a whole new ballgame when I turn on an amp. To paraphrase you,
'I wouldn't want to work with' an electric guitarist who had never played thru an amp. He'd be lost on stage with the unfamiliar EQ's, sustain, and volume. Just like if you only play sitting down at home, you're going to have a big adjustment learning to play standing on stage. Again, what matters with an electric is when it's amplified, it's not a complete music system without an amp. Who shows up to band practice or gigs without an amp? (
Answer: your buddy who just pawned his). You can practice an electric guitar any way you want at home, but the final product, gig or recording, is
always thru an amp. If you have several guitars, as most guys do, you can practice mostly on the ones that resonate best if that helps you.
