Fleor Hot Dual Rails Bridge Review – High-Gain Rail Humbucker Test & Measurements

FLEOR Hot Dual Rails Bridge Review

Fleor reviews have been among the highest-traffic articles on my site in recent months, so I decided to pick up the Fleor Hot Dual Rails Bridge as well. In fact, I bought it quite a while ago—but as I mentioned in my Duncan Black Winter review, I’d lost interest in high-output pickups for a long time. So after taking the measurements, this one ended up sitting in a drawer for months.

That is, until I tried the Black Winter and suddenly felt a spark of excitement for high-gain humbuckers again. Right after the BW, I installed this one, which had been waiting in the archive. I’ve been using it ever since.

My impressions and measurements are as follows… 

The Test Guitar

Fleor Dual Rails Bridge still standing on my “Pink Tiger”. That pink tiger is a superstrat has a Jackson Dinky body made of alder, one piece maple neck in modern C profile, German made Jackson Floyd Rose tremolo with Japanese stainless steel saddles, 25,5” scale, Stainless steel Jumbo frets, Alpha 500K pots and elixir strings in D# tuning. Guitar has Bare Knuckle Brute Force neck and No-name blade style middle pickups(~9K thou). Its primary (unplugged) tone is neutral to fairly bright.

Evaluation

Let’s read the desciption first, as always;

“A "hot dual rail" Blade style single coil humbucker pickup. The 'Rails' allow for a fatter, punchier sound than your traditional pole-pieced vintage pickups, perfect for when you need a screaming lead solo, or some heavy chugga-chugga! Powerful ceramic magnet coupled with stainless steel Rails generates take-no-prisoners tonality. High-output with treble bite and clarity, and punchy bass response. They have 4-wires allowing the option of coil-tapping, if required, or can be wired as per a traditional 2-wire humbucker. These are fully wax posted and vacuum sealed to eliminate any unwanted feedback and noise.”

If we take a look at the pickup’s appearance, it can be considered a typical dual-rail humbucker. Not quite like an X2N—more similar to a Duncan Dimebucker. Or Bill Lawrence–style designs may also come to mind. However, this one uses a single ceramic magnet. I didn’t open it up, but if it had multiple magnets like the BW or X2N, I would’ve easily detected it from the gauss readings. So it’s most likely a single ceramic magnet in standard size.

The mounting of the blade bars isn’t perfect from what I can see. There are slight gaps around the edges. It’s a very minor imperfection—still an imperfection nonetheless—but nothing you’d notice from a distance or at first glance.

The coils are not perfectly matched either. The slight asymmetry I observed in the FLEOR Pickups Alnico 5 Bridge—where the slug/north coil had slightly fewer turns—is present here as well. In fact, I have three or four other FLEORs built on the same winding architecture, and all of them show the exact same pattern in measurements. Generally, I believe that all of FLEOR’s 14–15K pickups are wound with the same gauge wire, same turn count, and the same general recipe. They just vary the hardware: some get hex poles, some traditional slugs-and-screws, and some—like this one—blade bars. Or they swap in different magnets.

Another detail that caught my attention is this: the current official website lists the baseplate as aluminum, and even the product photos support that. However, mine is definitely not aluminum—it’s nickel silver. You can see the original photos here as well.

In terms of inductance, the results were better than I expected. After measuring the coil resistances, I wondered whether the absence of an Alnico magnet would bring the inductance down to around 5.5–6H. But thanks to the steel blade bars, it sits at around 6.35H. The individual coil inductance is actually quite close to the Black Winter.

Honestly, if FLEOR had used three magnets inside this one as well, they might have ended up with a serious “Black Winter Killer”…

I installed the pickup on the guitar immediately after the Black Winter, which allowed me to compare them under the exact same conditions—same amp tone, same strings, etc. First of all, the pickup delivers a surprisingly solid tone for its price. It doesn’t quite reach BW’s level, but it still has a relatively full yet bright character. Chuggy riffs come across nicely.

The output isn’t as high as the BW’s. It’s definitely strong, but nowhere near BW territory—the difference is noticeable. Its response to palm-muted passages and pick attacks is very pleasing. When you stop a riff, the way it reacts isn’t as striking as on the BW, but if you ask whether that kind of response exists at all, it certainly does.

The clarity I’m referring to is, of course, mostly perceived in the uppermids. Considering the EQ curve, the lows are tight and precise, while the mids—especially the uppermids, as I mentioned—are strong and prominent. This leads in two things: i) it helps the guitar cut through the mix, and ii) if your amp isn’t set properly—especially with a bright guitar in standard tuning—it can produce a piercing harshness. For this reason, I can confidently recommend this pickup for guitars with lower tunings, darker-sounding guitars, baritones etc especially for rhythm & lead applications. I wouldn’t really suggest it for guitars with brighter nature, standard-tuned Strats or similar guitars.

When it comes to dynamic range, well, it is better than Duncan Black Winter. Better than JB but somewhere around Custom or Custom 5, i believe. So lowering the volume pot does make more audible difference then other kind of super power humbuckers thou.

Cleans? What cleans? Haven’t even tried. Simply because I never wondered about it.

Fleor Dual Rails is also a highly focused humbucker. Its purpose and tonal focus are limited. Nevertheless can be considered wider than Black Winter. Within those limits, it’s absolutely successful at what it does for that price!

So, what is the FLEOR Dual Rails’ purpose in music, and which styles is it suited for? As I mentioned earlier, guitars with lower tunings, darker-sounding guitars, and baritones can welcome this pickup with open arms. I have no doubt it serves as an excellent bridge between these guitars and high-gain amps. Of course, unless you plan to play polka metal with them, the most suitable styles will inevitably be modern and classic heavy metal.

Conclusion

The Fleor Hot Dual Rails Bridge proves once again that Fleor knows exactly how to squeeze impressive performance out of budget-friendly designs. It’s not a refined boutique humbucker, and it’s not trying to be one. Instead, it delivers a focused, aggressive, upper-mid–driven voice that works exceptionally well with darker guitars, longer scales, baritones, and lower tunings.

Its tight low end, cutting mid character, and strong attack make it a surprisingly capable partner for high-gain amps—far better than its price would ever suggest. While it won’t dethrone the Black Winter, it sits closer to it than anyone would reasonably expect from a pickup at this level. And thanks to its usable dynamic range, it responds better to volume-pot changes than many higher-output humbuckers in the same tonal neighborhood.

It’s not a pickup for everyone. Bright guitars and standard tuning will easily push it into harsh territory. Cleans are not its domain. And its tonal purpose is fairly narrow. But within that specific purpose—tight, modern, aggressive rock and metal tones—it performs extremely well and offers excellent value.

If your guitar lives in D, C#, Drop C or lower; if it naturally sounds dark; or if you simply want a modern, rail-style high-gainer that won’t collapse under saturated distortion… this little sleeper absolutely delivers.
