Looking for doom in all the wrong places? This meticulous recreation of the preamp from a rare ’80s amp is explosively effective.
Destructive amounts of volume, gain, and low end. Wall-of-amps doom in a box.
Somewhat confusing control labels and layout. EQ boosts can be subtle. You’ll probably want a noise gate.

If doom metal and its variants are big blips on your radar, you’ve probably noticed there’s a dearth of all-in-one stompboxes capable of unleashing genre-worthy filth and mayhem. A Big Muff (or any number of other fuzzes) and a distortion or two will take you a long way, but for dedicated doomers the aural onslaught usually isn’t just about cascading gain—it’s watts and decibels wreaking havoc on speaker cones. Which is why powerful heads (often 120- or 200-watt bass or PA models) from the likes of Sunn, Ampeg, Peavey, Orange, Hiwatt, Sound City, and Marshall largely rule the realm.
Another highly acclaimed amp for the task is Laney’s Advanced Overdrive Response series from the early ’80s, particularly the 50- and 100-watt Pro-Tube Lead heads, which had a handwired architecture much like a Marshall JMP circuit, only with an extra gain stage and a slightly darker sound. Influential doom/stoner/sludge bands who embraced AORs include Sleep, High on Fire, the Sword, and Electric Wizard. Of course, Laney’s doom cred goes much further back than that: Their most famous endorsee, Tony Iommi, is the veritable well from whence doom’s many tributaries spring—particularly his early Sabbath work, which was powered by Laney LA100 BL heads.
Frost Giant Architect Of Reality Review by premierguitar
Recorded with a Schecter Ultra III into the Architect, an Ibanez ES-2 Echo Shifter, and a Jaguar HC50 miked with a Royer R-121 (two feet back) and feeding an Audient iD44 interface going into GarageBand with no EQ-ing, compression, or effects.
- 0:00-0:16: Neck pickup with Architect bypassed.
- 0:16-0:39: Architect activated (red side only) with presence and bass at 3 o’clock, mids at 9 o’clock, treble at noon, bass and treble boosts engaged, master volume at 9:30, and preamp gain at 7:30
- 0:39-1:16: AOR (green side) engaged with AOR volume at just over 9 o’clock and AOR gain at max.
- 1:16-1:38: Bridge pickup into red side with presence at minimum, bass at max (and boosted), mids at noon (unboosted), treble at minimum (unboosted), master volume at 9:30, and preamp gain at noon.
- 1:38-2:08: AOR engaged with AOR volume at 10 o’clock and AOR gain at max.
But for Eric Calvert, head of Texas-based Frost Giant Electronics, AORs are where it’s at. In fact, his goal since founding Frost Giant has been to recreate the preamp in his own beloved AOR head from 1985. Now, with the help of Nick Williams (of Dunwich Amplification fame), Calvert’s dream has finally been realized with the Architect of Reality—a powerful homage to both Laney and, presumably, Sabbath’s 1971 sonic milestone, Master of Reality.
The Persistence of Realities
The Architect puts essentially every control from the front panel of an 8-knob AOR atop a medium-sized stompbox that’s billed as a “2-channel” design. But it’s more accurate to describe it as a massively powerful, wide-ranging distortion (right-side footswitch) with a cascading-gain feature (“AOR channel” footswitch) that can be layered over the base tone.
To help achieve its bludgeoning ends, the JFET-driven Architect converts 9V of AC power to a whopping 36V (battery power is not an option). The EQ—bass, mids, and treble knobs, corresponding boost toggles, and a presence (“pre”) knob—runs along the top row, but I found it peculiar that the master volume and preamp gain for the base tone (the “red channel”) are sandwiched between AOR (“green channel”) volume and gain knobs. The layout would feel more logical and intuitive—and therefore faster and easier to use—if AOR volume and gain were side-by-side above the AOR footswitch.
It’s capable of myriad metal flavors, but its real calling card is sheer might.
Speaker Bloody Speaker
To put the Architect’s intriguing ambitions to the test, I used a Les Paul, an Eastwood Sidejack baritone, and a Schecter Ultra III through a few different setups: a Revv G20 powering a Bogner closed-back 2x12, a Jaguar HC50 1x12, a silver-panel Fender Vibrolux Reverb paired with a Fender Rumble 200 1x15 bass amp, and a Sound City SC30 also paired with the Rumble. From the outset, the Architect’s massive volume and gain capabilities were apparent. The red side’s hot-rodded-Marshall-like preamp yields everything from toothsome gain excellent for old-school metal to blistering thrash at max. Meanwhile, the red side’s master volume is astonishingly loud—when I wasn’t using a bass amp (which allowed me to turn the guitar amp’s bass down), I began fearing for my speakers’ wellbeing when volume merely approached the noon mark.
But wide-ranging gain wouldn’t mean much if the EQ weren’t wisely focused. No matter where I dialed the treble, mids, and presence, tones never crossed over into abominable thinness. The bass control feels tight and muscular throughout its range, though it doesn’t seem particularly corpulent when maxed in red mode alone. But kick on the green side and it sounds absolutely explosive at all but the most conservative AOR settings. As with red mode, the AOR volume will likely sound like it’s clobbering your amp halfway through its range, even if the base channel’s volume is set pretty low. One couldn’t be blamed for using the green side to simulate pushing or literally push speaker cabs to their limits without looking back, but AOR mode is also capable of practical precision and subtle restraint—say, thickening things a smidge or adding razor sharpness to the core sound.
The Verdict
If you’re after droning, foundation-rattling gain and are sick of using multiple stompboxes and/or backbreaking stacks, you’ll find a lot to love in Frost Giant’s Architect of Reality. It’s capable of myriad metal flavors, but its real calling card is sheer might that occupies the mythical space between distortion and fuzz, where feral howls smudge together and destruction and chaos feel like real propositions. For extreme sounds—especially if you’re not miking your amp—it’s probably advisable to pair the Architect with a robust, high-wattage/high-headroom amp, if not also one of the many light, dependable bass amps on the market. But that’s a much more doable proposition than scouring the internet for rare, heavy-ass old stacks that keep going up in price.

A sample page from the author’s analog log.
Seasonal changes are tough on your acoustic. Here’s how you can take better care of your prized instrument.
As you read this, spring is in bloom in most of the US, or maybe it has been for some time. I’m timing this column specifically to ask acoustic guitarists, in this season of increasing humidity and comfortable conditions, to prepare for what’s coming. It’s never too soon, and time flies. Before you know it, we’ll be back to the maintenance phase and you might be blowing up the phones of your local guitar shops, luthiers, and techs. I’m here to encourage a decidedly old-school approach to preventative guitar maintenance, and yes, it starts now.
Why, you ask? Well, as the lead luthier at Acoustic Music Works, I can tell you that in my nearly 15 years in this position, this was the worst winter ever for preventable repairs on acoustic guitars. Fret sprout, bridge lifts, top sink, soundboard cracks, back cracks, loose binding, general malaise… These hit us very hard in the winter that spanned 2024 and 2025. Am I complaining? On the one hand, no. This is part of how we make our money. On the other hand, yes! Repair schedules related to dryness and humidity issues can stretch into weeks and even months, and nobody wants to be without their favorite instruments for that amount of time. With a little thoughtfulness, however, you might get through next winter (and every one thereafter) without hefty repair bills or time apart from your musical companion.
Our preparation is going to start with an unlikely but very important guitar accessory: the humble notebook. Plain, lined, grid, day planner… it doesn’t matter. We all need to actively participate in our instrument maintenance, and in my experience, fancy apps that track humidity via Bluetooth breed a kind of laziness, a feeling of safety that might prevent us from actually physically looking in on conditions. Better we keep an analog, well, log, so that we know where things stand, and I suggest checking in daily.
“This was the worst winter ever for preventable repairs on acoustic guitars.”
Track your relative humidity, both in the case and in the room where your instruments mostly reside, but also take notes on your action height, top deflection (StewMac has some great tips for measuring this) and anything related to playability that you believe you can observe empirically.
Dryness is the root cause of most guitar issues that manifest in the fall and winter months. Symptoms of dryness include sharp fret ends, falling action and dead frets, sunken top around the sound hole, and cracks and bridge lifts. With your trusty notebook, you’ll get a feel for the sensitivity level of your instrument, and that knowledge is power!
A few other basic implements will not only assist you in your observations, but may also satisfy your need to buy guitar-related things (at least for a minute). Getting quick and comfortable with a fret rocker is a great skill to have, and is invaluable in diagnosing buzzes due to high frets or frets that have come unseated due to dryness. A well-calibrated relief gauge might seem luxurious, but it can prevent you from making unnecessary or extreme truss rod adjustments. A string action gauge, or even a simple machinist’s rule or set of feeler gauges, will help you keep track of your action. Get a three-pack of hygrometers so you can average their readings, rather than depending on one.
Lest we forget: A guitar can not only be too dry, it can also be too wet. By beginning your maintenance diligence in the spring/summer, you’ll also be able to tell if your instrument is the victim of a too-humid environment. The signs of over-humidification are subtle: Your action may rise from a puffed-up top, and in extreme cases, glue joints could begin to fail. In my experience, an over-humidified guitar will suffer from dulled tone, almost like a sock in the sound hole. If you’re sensing a lack of clarity in your guitar all of a sudden, start with new strings. If it persists, it might be due to over-humidification, and you may want to introduce a desiccant to the case for a time. The more lightly built your guitar is, the more sensitive it will be to seasonal changes.
By getting into these habits early, you’ll be empowered by knowing your instrument more intimately. You’ll understand when and why changes in tone and playability might have occurred, and you’ll hopefully save on repair bills year-round. Feel free to reach out with any questions. Who knows? I might just send you a notebook with an AMW sticker on the cover!
This wonky Zim-Gar was one of many guitars sold by importer Gar-Zim Musical Instruments, operated by Larry Zimmerman and his wife.
The 1960s were strange days indeed for import guitars, like this cleaver-friendly Zim-Gar electric.
Recently I started sharing my work office with a true gem of a guy … one of the nicest fellas I’ve ever come across. If you’ve been following my column here, you might remember my other work mate Dylan, who is always telling me about new, fad-type things (like hot Honey guitars) and trying to convince me to use AI more. (What can I say, he’s a millennial.) But Steve, on the other hand, is about 10 years my senior and is a native New Yorker—Brooklyn actually, from the Canarsie neighborhood. Steve is a retired teacher and spent many years teaching in the Brownsville area of Brooklyn, and man, he has some amazing stories.
Mostly we talk about music and sports (he’s exiled here among us Philadelphia sports fans) and he’s just endlessly interesting to me. He has a huge appetite and can eat a whole pizza. When he talks, he sounds like one of the Ramones and he still has an apartment in Rockaway Beach. We both love Seinfeld and, like George Costanza, Steve knows where all the great bathrooms are across New York City. Since he’s been added to my circle (and is such a mensch), I decided I should work him into a column.
So here’s the connection: Back in the day there were many American importers, dealers, and wholesalers. A lot of them were based in New York, Chicago, and Los Angeles, but I only know of one guitar importer located in Brooklyn: Gar-Zim Musical Instruments. The company was run by Larry Zimmerman and his wife, and the couple had some success importing and selling Japanese guitars and drums. I used to see early Teisco imports with the Zim-Gar badge, which was the brand name of Gar-Zim. I’ve also seen Kawai guitars with the Zim-Gar label, but the Zimmerman’s seemed to sell cheaper and cheaper gear as the ’60s wore on, including the piece you see here.
“This build reminds me of the cutting boards I used to make in wood shop back in my high school days.”
The model name and factory origin of this guitar is a mystery to me, but this build reminds me of the cutting boards I used to make in wood shop back in my high school days. The guitar is just flat across the top and back, with absolutely no contouring or shaping. Its offset body is plywood with a thin veneer on the top and back. From a distance this guitar actually looks kind of nice, but up close you can see a rather crude and clunky instrument that offers little flexibility and playability. The non-adjustable bridge is off center, as is the tremolo. It was really hard to get this guitar playing well, but in the end it was worth it, because the pickups were the saving grace. Another example of gold-foils, these units sound strong and raw. The electronics consist of an on/off switch for each pickup and a volume and tone knob. The tuners are okay, and the headstock design is reminiscent of the Kay “dragon snout” shape of the mid to late ’60s, which is where I would place the birthdate of this one, probably circa 1966. Everything is just so goofy about this build—even the upper strap button is located on the back of the neck. It reminds me of that era when simple wood factories that were making furniture were tasked with building electric guitars, and they simply didn’t know what they were doing. So, you get oddities like this one.
Gar-Zim continued to sell guitars and other musical instruments through the 1970s and possibly into the ’80s. I once even saw a guitar with the label Lim-Gar, which is totally puzzling. I think there should’ve been a Stee-Gar designation for my new buddy Steve-o! Yes, good readers, with guitars and me, there are always just a few degrees of separation.

MOOER Gives Bassists What They Want with the New MBJ410 and MBJ420 Electric Bass Guitar Models
For 15 years, MOOER has built a critically acclaimed name for itself thanks to its cutting-edge electric guitars, pedals, and accessories. While the company is no stranger to building electric bass guitars, this has not been its focus for some time, hence why so many bassists are excitedly anticipating the release of the MBJ410 and MBJ420 electric bass guitars.
Both the bass guitars sport glossy Poplar bodies, keeping the price point affordable but without limiting their tonal resonance and versatility, whereas the MBJ420 holds the additional bonus of being built with a Poplar Burl top. Complete with roasted maple C-shaped necks (also accented with a gloss finish) as well as Roasted Maple fingerboards and White Shell dot inlays, the necks are designed to offer as much comfort as possible–a high priority for bass guitarists.
A 34" fret scale further enhances practicality for bassists, as does the neck's 12" radius. Strings are available in .045, .065, .080, and .100 gauges, providing something for any type of bass style - whether slapping, plucking, or picking techniques are preferred.Thanks to the industry-standard components of a dual-action steel truss rod and bone nut, the tuning and resonant stability of both the MBJ410 and MBJ420 models are also of a high standard. However, this is accentuated further by the guitars' strong and reliable BTN-1 tuning pegs, essential for heavier-gauge bass strings.
The tonewoods and structural integrity of the MBJ-series electric bass guitars wouldn't be complete without the accompaniment of the guitar’s two single-coil JB-style pickups. Combined with the MOOER BSC-2 bridge, both bass guitars have been carefully designed to amplify bass resonances excellently, complemented even further by their simple but effective tone dials. Two volume controls are also built in, ensuring that bassists can customize their sonic output to have the perfect tonal blend.
In terms of standout features, the main difference between the two bass guitars is the MBJ420's added poplar burl top, but most notably, the color selections. For the MBJ410, the bass guitar is available in Gunmetal Gray, Metal Green, and Metal Blue, perfectly suiting the stages of higher-gain performances. In contrast, the aesthetics of the MBJ420 are more classic, purchasable in Red Burst, Blue Burst, and Tobacco Burst. Finally, both guitars are topped with a chrome strap pin, enabling stylish and energetic live performances.
Overall, bassists will no doubt be excited to see MOOER return to electric bass guitars with the MBJ410 and 420 models. Of course, electric guitars will remain the focus for the company, but the release of these two new products is a reminder of just how accommodating MOOER is for its wide audience of musicians.
