The acoustic guitar amplifier might look a lot like a traditional electric guitar amp but there are a few major differences. The first major difference is an acoustic amplifier usually has a high frequency driver or tweeter, while a standard electric guitar amplifier does not. This tweeter or HF driver provides more treble allowing for a crisp and bright sound. If you plug an acoustic into a standard electric guitar amp without the tweeter, you will hear a darker or muffled sound. The other major difference is headroom. Electric guitar players normally like some gain or distortion to their tone, while an acoustic guitarist is looking for a loud yet very clean tone without distortion. The acoustic amp is right in between an electric guitar amp and a P.A. system, taking features from each to help you amplify your acoustic guitar. Below are some popular categories of acoustic amps and how they might fit your needs.
Battery Powered Amps
For the acoustic player on-the-go! Roland makes a few great battery powered acoustic guitar amps for the player who’s busking down in the subway, or the player who’s always on the road.
The battery powered Roland AC33 amp is one of the world’s first battery-powered amps made especially for the acoustic guitarist in mind. It runs on eight AA batteries, and packs a punch at 30 watts through twin 5 inch speakers. It also comes in an attractive Rosewood finish for that added touch of class.
For the guitarist with that might just be starting out, and is looking to expand their sound – look no further than the compact Roland Mobile AC battery powered amp. This hand-held amp is 5-watts and features two 4 inch speakers, and is able to produce a surprisingly large and lush stereo sound. You can also connect a portable media player to the AC input and jam along to your favorite tracks!

The stage amp is the classic amplifier for the acoustic player. They are generally high-wattage combo amps that give you plenty of headroom to give you a crisp, clear tone. The acoustic stage amp also features a tweeter in addition to the drivers you would normally find in your electric guitar amp. Roland, Fender, Marshall, and Fishman make some of the most recognizable and best-sounding acoustic amps.
The Fishman Loudbox Artist is a new take on the classic Fishman Loudbox 100, but with added power and portability. The Loudbox Artist packs 120 watts of clear sound, and a ton of headroom.
