ISP DECI-MATE NOISE GATE

Essential Information About the ISP Technologies Deci-Mate Pedal

• Ultra-compact noise gate in a micro pedal format, designed for pedalboards where every centimeter counts.
• Decimator technology with adaptive release for clear silence without cutting your sustained notes.
• Maximum noise reduction rated at over 90 dB, ideal for high-gain setups and noisy environments.
• True Bypass analog circuit to preserve tone and dynamics, without digital artifacts.

The Micro Decimator Format: Decimator DNA in a Field-Ready Enclosure

The Deci-Mate adopts the approach that made the Decimator family famous: reducing hiss and unwanted noise in real time while remaining as transparent as possible. ISP Technologies emphasizes a crucial point for demanding guitarists: a noise gate should not only "close," it must also follow the music. Thanks to an adaptive release capable of instantly switching from a very fast response (for staccato attacks) to a longer, smoother closure (for sustained notes), the Deci-Mate aims to avoid pumping effects and unnatural cut-offs often encountered with fixed release settings.

With its micro chassis, it clearly targets modern pedalboards: minimal footprint but a full implementation of the Decimator spirit, made in the USA.

Who It's For and Which Styles the Deci-Mate Makes a Difference In

The ISP Technologies Deci-Mate is designed for guitarists (and more broadly, instrumentalists) who want a clean sound between notes without losing the character of their amp or gain pedals. It excels in genres where background noise quickly becomes intrusive: punchy rock, hard rock, metal, djent, punk, but also funk or pop whenever compression, boosts, or chains of overdrive and distortion are used.

In the studio, it simplifies tracking by limiting hiss even before recording begins. Live, it provides immediate comfort: clean stops, controlled silences, and a more "professional" feel when alternating palm-muted rhythms and leads. It is also a very relevant solution for compact pedalboards, fly-date rigs, or any setup where effective noise reduction is desired without adding multiple boxes.

Key Features: Adaptive Release, Analog Transparency, and Easy Integration

The strength of the Deci-Mate lies in its adaptive response: instead of forcing you to choose a compromise (fast release to kill noise, at the risk of truncating long notes), the pedal automatically adjusts its behavior by following the signal envelope. ISP highlights the "Decimator X" technology based on time vector integration, designed to limit unwanted modulation and make the release particularly smooth on sustained notes.

Its fully analog architecture aims for transparent noise reduction without aliasing or a digital processing feel. On the integration side, True Bypass keeps the signal path intact when the pedal is off, an important point for guitarists who want to maintain the same touch response and brightness in bypass mode. Simply plug it between your guitar and the rest of your chain (or at the most strategic point on your pedalboard) to contain noise where it appears.

Sound

A good noise reduction should be heard mainly by what it removes, not by what it adds. The Deci-Mate is designed to remain neutral: no intentional coloration, no marked compression, and a preserved dynamic feel as long as the signal is above the threshold. Its adaptive behavior aims to provide clean silences without "eating" note endings, making it particularly pleasant on sustains, bends, and leads, while remaining fast enough for precise riffs and sharp attacks.
