The electric guitar changed its status to a rockstar instrument that fills stadiums. That could not have happened without the guitar amplifier. That cool box of electronics that make your guitar strings create loud, and often distorted, noise that sounds so good.

The problem is that you can’t exactly carry your amp around the way an acoustic busker does. That is, unless you get one of these battery-powered mini amps that you can just clip to your belt.

Want to shred at a picnic?
Why not?

Need to practice while away at camp?
Who needs to go outside anyway?

This micro amp is made by Marshall, possibly the most respected name in guitar amplification. It has one watt of power and runs off a nine volt battery. It’s literally small enough to fit in the palm of your hand. What’s especially nice about the MS2 amp is that it looks like the big Marshall cab units you see at professional rock concerts.

This doesn’t come with an adapter out of the box, but you can add your own 9V AC/DC wall wart for just a few bucks if you don’t feel like going through a bunch of batteries. Yes, this isn’t as loud as even a 10 watt practice amp, but you aren’t going to hook that to your belt and still be able to play anything.

While it may seem like a bit of a novelty, the micro amp has actually been a bit of a revolutionary product since it first came out. It’s changed the way people practice and where they can perform.

Either way, it’s hard to imagine any musician not having some use or appreciation for a battery-powered micro amplifier, and it’s priced just right too!
