Description
For any tech running a guitarist’s pedalboard, unwanted noise floor is the enemy of a clean mix. The ISP Decimator X G-String tackles this at the source by tracking the signal straight from the guitar rather than downstream, so switching between clean tones and saturated high-gain sounds doesn’t require re-dialing a threshold setting mid-set. That kind of stability matters when a rider calls for consistent gain-staging across a whole show.
Its updated design lets you patch the processing channel into an effects loop, or place it after high-gain pedals and preamps, giving you flexibility to fit it wherever your existing signal chain needs cleanup. Need more than one channel of noise control? A 1/8" phone cord links two Decimators together, or pairs a G-String X with a standard Decimator X to build a stereo rig — both units tracking the instrument directly for performance that mirrors the rack-mounted Decimator ProRack G used on larger stages.
Under the hood, Linear Time Vector Processing handles the envelope tracking with a smooth, ripple-free response — quick enough to catch short staccato notes cleanly, yet controlled enough to keep long sustained passages free of artifacts during downward expansion. Setup is straightforward, which matters when soundcheck time is tight.
