About This Item
Description
Squeezes ISP's full Decimator G circuit — including a send/return loop and direct-guitar tracking — into a micro pedal so you can switch between clean and high-gain tones without re-adjusting the threshold.
Which ISP Decimator is this?
ISP's noise-reduction line has two generations. The compact micro pedals — Deci-Mate and Deci-Mate G — use the earlier analog Decimator circuit. The full-size Decimator X and Decimator X G String use the newest patented Integration Release Window technology (US Patent 11,641,183) that keeps long sustained notes decaying naturally.
- vs. Deci-Mate Micro: The Deci-Mate Micro has no loop and tracks only its own input, so its threshold needs re-adjusting when your gain changes; the Deci-Mate G adds a 3.5mm TRS loop and tracks the guitar directly for constant performance across gain settings.
- vs. Decimator X: Decimator X is a full-size, single-channel pedal with the newer Integration Release Window technology but no loop; the Deci-Mate G is a micro pedal built specifically around loop-based, direct-guitar tracking from ISP's earlier G-circuit generation.
- vs. Decimator X G String: Decimator X G String offers the same direct-guitar-tracking concept as the Deci-Mate G but in a full-size chassis with four 1/4-inch jacks and the newest X-series adaptive release technology; the Deci-Mate G is the compact, 3.5mm-loop version built on ISP's earlier circuit.
Why guitarists choose this pedal
- Tracks the guitar's direct output, so the noise floor stays constant even when you change gain-heavy pedals or preamp settings
- No threshold re-adjustment needed switching between clean and extreme high-gain tones
- Built-in 3.5mm TRS loop with included interface cable to insert noisy pedals or tap an amp's series effects loop
- Full G-circuit functionality in a micro-pedal footprint
Controls and switches
- Threshold knob – sets the downward-expander threshold; because the G circuit tracks the direct guitar signal, one setting works across gain changes
Power and pedalboard compatibility
- Voltage: 9V DC
- Current draw: 40 mA
- Polarity: center negative (tip negative / sleeve positive), standard 5.5 × 2.1 mm barrel
- Battery: no – requires external 9VDC adapter, minimum 40mA, not included
- Bypass: True bypass
- Signal-chain placement: guitar → Guitar IN; Guitar OUT → gain pedals / amp input; amp effects-loop send → DEC IN, return → DEC OUT. Delay and reverb sit after the DEC OUT so their tails stay natural.

Frequently asked questions
What does the 'G' loop actually do?
It lets you insert your gain/distortion pedals (or connect to your amp's effects loop) into the Deci-Mate G's loop, so the pedal tracks the clean guitar signal directly instead of the noisier post-gain signal.
Do I need to readjust the threshold when I switch from clean to high gain?
No — because the Deci-Mate G tracks the direct guitar output, the same threshold setting works across gain changes.
What cable does the loop use?
A 3.5mm TRS interface cable, included with the pedal, connects the loop to your other pedals or amp's series effects loop.
Can this run on battery power?
No, it requires an external 9VDC adapter (minimum 40mA, center negative); there is no internal battery compartment stated for this model.
How is this different from the plain Deci-Mate?
The Deci-Mate G adds the loop and direct-guitar tracking; the standard Deci-Mate has a single input/output with no loop and tracks the pedal's own input signal.
