The ISP Technologies DECI-MATE G Micro Decimator is a guitar noise reduction pedal, built as a micro pedal that puts the company's Decimator-based gating into a small footprint. ISP Technologies describes it as a full implementation of the world renowned Decimator G circuit, with new patent pending tracking improvements, all in a small, micro pedal package1. It is true bypass and, according to Pedal of the Day's review, all-analog12.
Where it came from
ISP Technologies fits the DECI-MATE G into a micro pedal package, with a chassis measuring 3.7 inches x 1.5 inches x 1.3 inches1. The pedal carries a full implementation of the company's world renowned Decimator G circuit in that small format1. ISP describes the result as a guitar noise reduction pedal that is amazingly smooth and transparent, with an all-analog design that keeps your tone unaltered2.
Controls, connections and power
The pedal takes one 1/4 inch guitar input and gives one 1/4 inch output, with an input impedance of 500k ohms1. Its release response is adaptive over a 1000 to 1 ratio, which is how the gate decides how quickly it closes after a note stops1.
No power supply is included. The pedal needs 9V DC at 40 milliamp minimum, with tip negative and sleeve positive polarity1.
What reviewers said
Pedal of the Day reviewed the pedal in April 2020 and described its gating character in these terms2:
"It is amazingly smooth and transparent, and the all-analog design makes sure you won't alter your tone in the least."
The same review framed noise gates generally as essential for players with loud, high-octane rigs to keep feedback and volume at acceptable levels, adding that "anyone with any kind of noisy rig would be a fool to not give it a go"2.
How it compares
The Deci-Mate G sits in a crowded field of noise gates. ISP's own range runs from the original ISP Technologies Deci-Mate and the ISP Technologies DECI-MATE Micro Decimator to the full-size ISP Technologies Decimator G String Pedal and the newer ISP Technologies Decimator X. For a wider look at the type, see the site's page on Noise Gate Pedals2.

Questions
Does the ISP Deci-Mate G come with a power supply?
No. ISP Technologies lists the power supply included as NO on the product page, so you will need to provide your own 9V DC adapter rated for at least 40 milliamps. The pedal's power input is tip negative and sleeve positive, the standard polarity used by most pedalboard power supplies.
Is the Deci-Mate G true bypass?
Yes. ISP Technologies lists True Bypass as Yes on the product page, so when the pedal is off, your guitar signal passes through without the gate circuit in the path.
Is the Deci-Mate G an analog or digital noise gate?
It is analog. Pedal of the Day's review describes the all-analog design and says it makes sure you won't alter your tone in the least. The gate's release response is adaptive over a 1000 to 1 ratio, according to ISP Technologies.
What is the difference between the Deci-Mate G and the Decimator G String?
The Deci-Mate G is a micro pedal that ISP describes as a full implementation of the Decimator G circuit, with new patent pending tracking improvements, in a chassis of 3.7 by 1.5 by 1.3 inches. The Decimator G String is the company's separate full-size pedal built around the same family of noise reduction.
How much noise reduction does the Deci-Mate G give?
ISP Technologies lists the maximum noise reduction as greater than 90dB, with a maximum input level of +10 dBU. That is the headroom the gate has to work with before the input clips.
