You cannot plug an acoustic guitar into any kind of amp because it lacks the electronics. An acoustic/electric guitar, however, is the same as an acoustic guitar but with electronics and a battery component so you can amplify it. If you’re using a simple acoustic guitar, a pickup or additional mic is needed.
Keeping this in consideration, do acoustic and electric guitars need different amps?
To maximize the functionality of an acoustic-electric guitar, you’ll need an acoustic guitar amplifier. Even if you already have an amp that you use for an electric guitar, getting an amp specifically designed for an acoustic would be better because it can do wonders for your sonic output.
Moreover, what makes an acoustic guitar amp different? Acoustic guitar amps aren’t just PA (Public Address) systems. They often have more controls and effects settings designed to emphasize an acoustic guitar’s natural sound – which is different from that of an electric guitar with no natural resonance.
Also question is, what’s the difference between an acoustic amp and an electric amp?
Electric guitar amps amplify an electric guitar signal providing more gain (for distortion), volume, effects for diverse sounds whilst slightly coloring the tone. In contrast, acoustic amps are designed to amplify a ‘clean’ and ‘transparent’ signal with notably more ‘headroom’ optimal for the clean sound of acoustic.
