Lunchbox Amps – FAQ & Buyer’s Guide!

Written by Owen Smith

A lunchbox amp is a box the size of a lunchbox that houses an amp system. These amps were created for musicians that wanted an easily transportable device that would let them practice, jam and perform in small gigs without all the contrivance of a large amplification system.

One of the biggest issues with guitar amps is the power that many performers think they need but don’t really understand the power of watts. Amplifiers are scientific electronic devices created to amplify the low decibels of a guitar to noise levels that can be heard for all audiences.


ider that the so-called 50 to a 100-watt amp is the standard box amp you think of, but that’s a misconception or misunderstanding of amp power.

A good loud amp for home and practice use is only 3-5 watts. An amp for jamming at home or in a garage is around 10 watts, an amp for small performances including outdoor improve. is typically 15 to 20 watts and an amp for performing with bands would be around 30 watts. If you want an amp to project to a large auditorium or gig, then you go above 50.

Lunchbox amps were created to combine both the power of a versatile, lightweight, portable amp with the power of loud system when connected to powerful speakers. Since lunchbox amps combine a speaker with an amp, you have to look for a professional model and not some anonymous brand. The reason is pure science. Understand that the amp doesn’t produce sound, it merely produces an electrical current that carries the sound wave order to the speaker which converts the current into sound. Therefore the speaker is as important as the amp, and the amp must be equal to or more powerful than the speaker. However, don’t buy an amp that is more than double the power of the speaker, or you might end up damaging the speakers.

Now, having stated all about power, you will be surprised to see some powerful amps presented here, including a 200-watt lunchbox speaker that is designed for professional use and will blast the socks off anyone standing too close. In other words, when you use a lunchbox amp, don’t let its small size fool you or anyone, if you invest in a powerful amp, over 50 watts, make sure the volume is set to low; otherwise, you will be arrested for sound terrorism.

When investing in an amp, consider all the features you need, and only invest in an amp that provides you with the versatility that you require. In other words, if you don’t use it, don’t buy it. Test the amp by twiddling the knobs and checking its performance with your guitar.

A quick word about Headroom

Headroom is all about sound distortion. Headroom is the difference between the maximum level and the normal operating level that the amp can pass without distorting the sounds. Since musical instruments provide wide variations in dynamic range; without enough headroom, you get frequent distortion (clipping).

As such, when you have a limited budget or purchase legacy equipment that uses a lower power amp, take care that you have enough headroom or you will end up damaging your speakers from a low power result too.

What are Impedance and Ohms?

Ohms are measures of resistance. Amps work with 4, 8 or 16 ohms of resistance. The best amp speaker configuration is when the loudspeaker’s power is exactly correct for the amplifier.

You can connect more than one loudspeaker to an amp, and there are two methods, these are dual and parallel.
The parallel is when you divide the impedance by the number of speakers connected, for instance, if you have four speakers that are rated at 16 ohms, you take 16/4 to get the overall rating of 4 ohms.

To sum up, you will notice that I don’t mention all the superlatives of sound. Some will mention how throaty and deep their amps are. That’s a load of hogwash; an amp is an electronic device used to amplify sound, full stop. The speakers are the units that convert sound and can make them meaty or beefy, or whatever mother menu item is on the list. One final word on amp foodstuffs, setting and controlling an amp will deliver different tones and sounds, ultimately it’s about knowing how music is converted from analog to digital. So when you invest in an amp, also play around and practice with the dials and fiddle about till you comprehend and understand the different values you can get from an amp and speaker combo. For this, it’s wise to consider buying an amp that has multi-channel and has a separate EQ for each channel.
