Demonfx G String Noise Reduction Filter Review: Is This Budget Decimator Clone Worth Your Money?
If you play electric guitar, you already know the familiar, maddening hum that creeps out of your amplifier the moment you crank up the gain or click on a heavy distortion pedal. There is nothing quite as frustrating as crafting a massive, bone-crunching tone, only to have it ruined by an intrusive buzz, a persistent hiss, and annoying single-coil 60-cycle hum between riffs. In a live setting or a quiet studio environment, this unwanted noise can completely sabotage your performance, muddying your dynamics and exhausting your ears. We have all spent hours chasing ground loops, swapping out patch cables, and messing with isolated power supplies, often realizing that high-gain preamps simply demand a serious noise suppression strategy.
Leaving this signal degradation unchecked does not just make your playing sound sloppy; it robs your guitar of its natural punch, clarity, and articulation. When your noise floor is constantly fighting against your actual signal, your playing gets buried under a wall of static. That is precisely why we decided to put the Demonfx G String Noise Reduction Filter through its paces. Designed to tackle unruly noise directly inside your effects loop and signal chain, this pedal promises studio-grade silence without butchering your natural guitar tone. Let us dive deep and see if this unit lives up to the lofty expectations set by high-end industry standards.
- Based and inspired by the original G Series, this is Demon's take on a very useful addition to your signal path.
- Control unwanted noise at certain points in your signal chain.
What to Consider Before Buying an Electric Guitar Noise Gates Effects Pedal
An Electric Guitar Noise Gates Effects pedal is more than just an item; it is a key solution for controlling unwanted noise at specific points in your signal chain, allowing you to run heavy distortion without dealing with a messy background hiss. When you push your amplifier’s preamp section or stack multiple overdrive pedals together, your noise floor multiplies exponentially. A quality noise reduction unit acts as an intelligent gate, clamping down on silence while instantly opening up the moment you strike a string, preserving your picking dynamics and transient response.
The ideal customer for this type of product is someone facing severe high-gain feedback issues, hum-laden single-coil pickups, or complex pedalboard signal chains that act like giant radio antennas. Conversely, it might not be suitable for ambient players who rely on massive, decaying reverb and delay tails that a harsh gate might chop off prematurely. If you fall into the former camp, you will want to look closely at pedals that support advanced routing methods. Before investing, consider these crucial points in detail:
- Dimensions & Space: Pedalboard real estate is always at a premium, meaning you need to evaluate how a pedal physically fits alongside your existing stompboxes. The Demonfx G String Noise Reduction Filter features a standard footprint that easily integrates into most boards, though you must account for extra patch cable routing if you plan to utilize its dedicated loop capabilities. A well-designed housing ensures it will not crowd your power jacks or footswitches during live performances.
- Capacity/Performance: Understanding how a noise gate interacts with your specific signal path is vital for achieving transparent performance. Unlike simple in-and-out gates that sit at the very end of a chain, advanced units allow for selective noise reduction by tracking your clean guitar signal directly. This ensures that even when your preamp is screaming with distortion, the gate reacts naturally to your guitar’s dry input without choking your sustained notes.
- Materials & Durability: Touring musicians and gigging guitarists need gear built to withstand the rigors of the road, heavy foot stomps, and unpredictable stage environments. Sturdy metal enclosures and heavy-duty components protect the internal circuitry from dust, static discharge, and physical impact. We always recommend checking the quality of the jacks and pots to ensure long-term reliability under constant use.
- Ease of Use & Maintenance: Dialing in a noise suppressor should enhance your workflow, not turn into a frustrating guessing game every time you change venues or gain structures. Intuitive threshold controls and clear status indicators make it easy to dial in the sweet spot between total silence and natural note decay. Low-maintenance design means you can focus entirely on your playing rather than troubleshooting your signal path.
Choosing the right suppression unit can completely transform your rig, turning a noisy, chaotic mess into a tight, professional-sounding machine that responds instantly to your touch.

Deep Dive Into Performance: Putting the Demonfx G String Noise Reduction Filter to the Test
Mastering the 4-Cable Method Setup
The true magic of the Demonfx G String Noise Reduction Filter becomes fully apparent the moment you wire it up using the four-cable method. In our studio tests, plugging straight into the front of the pedal and routing through the amplifier’s effects loop completely changed how the gate interacted with our tone. Instead of simply clamping down on the end of the chain and squashing delay tails or reverb decays, this unit monitors your guitar’s clean input signal directly. This means the detector knows precisely when you are playing and when you have stopped, allowing the gate to slam shut on preamp hiss without choking out your sustaining lead notes. When we paired this setup with a high-gain distortion pedal upstream, the background hum vanished instantly into absolute silence the second we muted the strings. It is a feature that really sets it apart from basic budget stompboxes that often introduce pumping or artificial gating artifacts.
Transparency and Tone Preservation
One of our biggest fears when testing budget-friendly clones of high-end rack and pedal units is tonal degradation—specifically, the dreaded loss of high-end sparkle or muddying of low-end punch. To put the Demonfx G String Noise Reduction Filter through its paces, we engaged and bypassed the unit repeatedly while tracking clean chords, crunch rhythms, and screaming saturated solos. To our pleasant surprise, we detected zero tone suck or high-frequency roll-off. The bypass mode is clean, and when engaged, the pedal leaves your core guitar tone completely uncolored. Whether we were digging into glassy single-coil blues riffs or chugging on dropped-tuning humbuckers, the dynamic response of our instrument remained completely intact. If you want to see its full feature set and user reviews, you will quickly notice that transparency is one of its most widely praised attributes among working musicians.
Performance Under Extreme Gain and Live Conditions
To simulate a worst-case scenario, we stacked multiple boost and distortion pedals in front of a high-gain tube amplifier head, creating an absolute breeding ground for feedback and 60-cycle hum. Without any noise suppression, the rig was virtually unplayable during pauses, squealing and hissing aggressively. Dropping the Demonfx G String Noise Reduction Filter into the chain reined in the chaos immediately. With a simple turn of the threshold knob, we found the sweet spot where the background hash disappeared into total blackness, yet the gate opened smoothly the microsecond a pick hit a string. We experienced zero choppy gating or robotic stutter, even during lightning-fast thrash metal palm-mutes. It performs like a high-end studio processor housed inside a compact stompbox, proving itself more than capable of handling demanding live stage environments where fluorescent lighting and dodgy venue wiring threaten your tone.
What Other Users Are Saying
Listening to feedback from musicians who have put this gear through real-world testing gives us a fantastic baseline for long-term reliability. The consensus from players who use the Demonfx G String Noise Reduction Filter is overwhelmingly positive, especially regarding its financial value. One musician noted that it is “really impressive, and you can’t beat the price,” highlighting how accessible high-end noise control has become. Another user pointed out that it “works as it should” as a faithful clone of the expensive ISP Decimator, noting that it “works best using 4 cable method” with “no tone issues” while running alongside high-gain drive clones. Perhaps the most striking endorsement came from a seasoned player who stated, “Don’t pay for the orig, this does the trick as good had both this is 200 dollars less it’s a no brainer,” cementing its reputation as an absolute steal for guitarists on a budget.
