“...to me!”
In discussions about the pantheon of late-fifties, early-sixties rock guitarists, you'd be doing yourself a disservice skipping over Trini Lopez. Early rock guitar, a conversation definitely dominated by your Chuck Berrys, your Buddy Hollys, and your Ritchie Valenses, certainly has a spot for Lopez. The guitarist has since become something of a household name for hollow- and semi-hollowbody fans for his two custom-designed Gibson guitars and for one of his signature songs, a cover of Pete Seeger's "If I Had a Hammer," or, "The Hammer Song."
Lopez's "Hammer" climbed the Billboard chart to number three, and what a hammer it still is today.
If Trini had this hammer, it's safe to say that maybe the smiley rock of the early sixties might have taken a different turn. The world may never know.
This is the Electronic Audio Experiments Greathammer Bass Overdrive.
Hammering Down
Introducing the Electronic Audio Experiments Greathammer
It's fun to theorize, yet probably at this point impossible to know, what the pioneers of rock and roll might think about today's rock guitar world. When you're panicking over Elvis's hips on your twelve-inch black-and-white Westinghouse, what chance do you have with the twenty-first century and a motley crew like Electronic Audio Experiments?
Electronic Audio Experiments, Boston's busiest bunch in forward-thinking, analog-minded, high-fidelity effect pedals, has had a pretty busy year. With releases like their Mirror House V2 modulator and Glaive op-amp fuzz peppering their 2025, the gang kicks off 2026 on the right foot with this, their Greathammer Bass Overdrive.
ObstructedThe Greathammer follows in the heavy, deeply impressed footsteps of limited-release pedals designed in collaboration with boutique music brand Obstructures. These releases originally delivered, on incredibly tight quantities, visions of particularly coveted Canadian solid-state bass amps. Such amps breathed massive solid-state power into a bass rig... how much? Like, woah. Like that much, give or take. Today's Greathammer follows such an example with formidable solid-state-voiced character of its own. The Greathammer, as it happens, is part of Electronic Audio Experiments' main production line and is not limited. Luckily for fans fiending for coveted Canadian solid-states, the Greathammer is here to stay.
This pedal punches in with quite a bit of that classic EAE reinvention and smaller considerations for playability sprinkled along the way. Of course, these considerations and reinventions leave plenty of space for the blissful simplicity really any overdrive should have. We're getting ahead of ourselves, though. Let's talk some specifics.
If He Be Worthy...
Electronic Audio Experiments Greathammer Bass Overdrive Controls
The Greathammer falls quite neatly into the Electronic Audio Experiments line for its crack analog design, short distance to inspiration and, of course, mountains of gain on tap. As we can see, the Greathammer is laid out simply with four intuitive, highly interactive controls and a three-way mids switch. Really easy stuff to get you on your way. Let's run down these knobs.
Electronic Audio Experiments Greathammer Bass Overdrive Controls
- Level – It'd be a pretty sorry drive without a master volume, eh? Like we said, really simple stuff. Clockwise for more, counter for less. As is the case with many great analog drives, the Level control actually does play a pretty big role in tonal mixing down the road. One second on that thought.
- Gain – The beef in this all-beef patty. EAE's mastery of analog drive really shines here with about fifty decibels of gain on tap with this control. If you're after the enormous, amplified tonality you'd expect out of a solid-state bass amp, you won't be disappointed with the amount of gain on this dial alone. You can quote us on that.
- Bass – A post-clipping low-frequency shelf boost. Focusing in on frequencies below 100Hz, this specialized frequency boost is perfect for this pedal, just in case you didn't have enough bass in your bass.
- Attack – Fairly unique to the Greathammer, Attack doesn't really act as a traditional tone control. This dial homes in on pre-gain tone, which in turn deeply shapes the playing response of the drive. Pretty big stuff for replicating the playing response of a solid-state amp.
- Notch – A three-position mid-cut toggle. In the event you're feeling even more sinister when it comes to crushing, mid-scooped drive tones, EAE is one step ahead of you. Starting at flat and working your way up (or down, depending on which way you're looking at your mid-frequency hump), the Greathammer's Notch effectively digs out mids for even gnarlier amp-like breakup.
These fairly straightforward controls all together line up for a control scheme with no questions asked. More for more, less for less. You get the idea – but how does this hammer drop? We thought you'd never ask.
Hammer Time
Electronic Audio Experiments Greathammer Bass Overdrive Tones
When you find yourself eyes bloodshot, sweat dripping, Monday clock-in mere hours away and dozens of Reverb search pages deep for "solid state bass amp," know that the Greathammer is here for you. The Greathammer, to maybe get a little cheap with our wordplay and descriptors, is just that. It's a massively powerful solid-state-style drive in analog components. Where are we swinging this hammer, though? And what are we hitting?
EAE's Greathammer starts loud and ends loud, if you can believe it. You might not have the immediate sense of scale in your mind, the "How many football fields long..." of sound yet to contextualize fifty decibels of onboard gain, but trust us, you quickly will with the Greathammer. Placing your Gain at noon and your Level at about nine* will get you going fairly quickly. The Greathammer can either fire up an already driven amp or even do some solid driving of its own.
With the Greathammer, you get heaping doses of both low-end force and top-end burn, as dictated by the Bass and Attack controls. Even when playing a Precision-style bass, or something similarly thumpy rather than punchy, the Greathammer cuts to the chase with plenty of gain and grind on tap towards the top-end. EAE's solid grasp of analog drive and breakup shows itself splendidly with a bass overdrive that can get reliably driven in more classic ways or even more off-the-wall ways with the Attack punched and the mids scooped. In short, there's a million ways to swing a hammer and plenty of delicate, expensive, precariously-placed things to knock over in the process.

Hammer to Fall
Electronic Audio Experiments Greathammer Bass Overdrive Further Functions
As we start slowing down on our hammer time, let's round up a couple of the smaller considerations put in motion by Electronic Audio Experiments to put this pedal on another level.
- Intelligent Switching – One of the things EAE has become revered for in recent years, in our eyes anyway, is their working of intelligent, soft-touch footswitches into pedal types that less-than-traditionally see them. Like a couple few of their most recent outings, their Glaive op-amp fuzz being one of them, the Greathammer features a silent, soft-touch footswitch that also allows for momentary operation. Hold the switch down, drop the hammer. Lift it up, lift it up.
- Standard Power – With all this talk of massive helpings of tone, you might think the Greathammer's power requirements would trail easily into the prohibitive. Luckily, that's not at all the case. Standard nine-volt DC center negative power requirements at a respectable 70mA minimum bring this pedal everywhere and anywhere.
- Use In Guitars – Alright, so it's always a drag to bring the guitarist to the bass party, we know. This was an exclusive event, invite-only, the sign clearly states so, we apologize. However, while the Greathammer's forte is with basses, it performs impressively with guitars that could stand to get a dose of low-end drive. Whether you're a bassist or otherwise, the Greathammer is a great pick for a multi-purpose overdrive.
Electronic Audio Experiments Greathammer Bass Overdrive Final Thoughts
There is a sequence at the end of Avengers: Endgame that still gives us the shivers. We won't spoil it if you haven't seen it, but with all this talk of hammers, you know what we're talking about if you know what we're talking about. The Greathammer definitely delivers a similar kind of Act Three warm-and-fuzzy, fist-pumping vindication. Electronic Audio Experiments outdid themselves here in terms of translating a sound that is certainly specific, but also universal. Solid-state amps maybe aren't exactly what they used to be with influence, but for the solid-state fan out there clamoring for new spins on their favorite models, it's hard to imagine needing to ask for something more.
