A high-performance Class D power amp in a pedal

Gone are the days of lugging around heavy guitar power amplifiers - and we can be thankful for it. Modern Class D power amps pack an enormous amount of power into a highly compact, lightweight package - and the Harley Benton GPA-100 is no exception. This little powerhouse comes in a pedal format and delivers an output of up to 190 watts at four ohms, making it the ideal solution for guitarists and bassists who are looking to make their rig powerful enough to always be heard, but also don't have a lot of space to spare. The GPA-100 features a three-band EQ, a master volume control, and indicator LEDs for signal and peak, so players always have a good overview of what is going on. What is more, its sturdy metal chassis ensures functional reliability even when the pedal is used under extreme conditions.

Immense power with a tiny footprint

Thanks to its compact dimensions of just 162 x 100 x 64 mm, the GPA-100 can easily be integrated into an existing pedalboard and provides a complete replacement for that heavy rack-mounted power amp. Its three-band EQ (bass, mid, and treble) lets you easily make final tweaks to the signal coming from your preamp, pedal board, or multi-effects unit and thus get your desired sound. Being the most important control, the master volume - which is located at the bottom edge of the pedal's robust metal chassis - features an extra-large knob. All of the potentiometers are firmly screw-mounted to the front of the pedal, so they will be safe from harm if they accidentally get stomped on. Rather than an internal fan, which could become irritating over time, the GPA-100 features sufficiently large openings at both ends of the chassis to ensure adequate cooling even during heavy use for long periods of time. To top it all off, two LEDs - one each for signal and peak - are provided to allow the incoming signal to be monitored and optimised.

A power amp for all occasions

Players who use guitar rigs of any description or modellers like the Kemper amp series and Axe FX Fractal systems, and of course bass players who want to make their preamp audible will find the GPA-100 an interesting alternative. The compact power amp's output of up to 190 watts at 4 ohms should be sufficient for a wide range of applications, and it also comes at the kind of highly affordable price that is typical of Harley Benton. The GPA-100 is thus a particularly interesting option for musicians on a tight budget. However, it also offers many benefits for professionals, not least of which is the balance it strikes between compact dimensions and high performance.

Tinitus on a Budget
Impurist 10.02.2022
Was searching for a discreetly-sized, emergency back-up power amp in case my live rig died on the road. It can (and does) happen and can be a gateway to a realm of nightmares.

The price initially made made laugh, but when something is that cheap you really have nothing to lose so I took a gamble. Believe me, I won.

A solid unit with metal chassis, incredibly simple to use, and thankfully NO WALL-WART.

The sound is transparent enough in a serious live situation for no-one, not even you, to notice you're essentially playing by the grace of a glossy, black brick...unless you want to mess with the provided low-mid-treble dials which can certainly add some character. I leave them at 12 and dial on my pre-amp though.

Anyone who says this runs "quiet" is using it wrong, or needs a hearing aid: it easily keeps up with my Mesa Boogie Roadster. Read the instructions.

As it stands, I am considering ditching my over-priced, over-weight valve amps to use this exclusively on the road. I could carry an extra 3 in a tote bag and keep my back, wallet and pride intact when the "real" thing fails.

Beyond impressed. I'm going to buy a couple more eventually.

The Best Cheap Power Amp?
NickB1234 29.04.2021
I use this to power my HX Stomp into a 1x12 or 2x10 cab for jam nights and rehearsals.

As a power amp it doesn't respond like a tube power amp. Its response is more linear. The Fryette PowerStation in that respect is a far superior product.But, if you're starting out in the modelling world and want a cheap and cheerful power amp, then I can wholeheartedly recommend the GPA-100. The tone controls are effective for fine tuning your tone and it's compact enough to chuck into your gig bag.

Would I buy it over the Seymour Duncan PowerStage? Yes.

It does what it is supposed to at an unprecedented form factor and price!
Zaczes 15.02.2022
This thing makes my guitar go louder at a fraction of the cost of a rackmounted power amp. And a fraction of its weight. No, seriously, I just put it in my backpack and I'm all set. Does it sound as good as my butique, tube power amp? I don't care - it seems transparent to me and it doesn't weigh like 20 kg. Absolute gamechanger for touring with a digital FX unit.
