Best Alternatives To Boss NS-2 Noise Suppressor
Boss's noise suppressor/gate — the industry standard for removing 60-cycle hum, single-coil noise, and high-gain amp noise from a signal chain. The NS-2 has two connection modes: standard (in signal chain between guitar and amp) and send/return (where the pedal drives the gate using the clean guitar signal, but cuts the noisy processed signal). The send/return mode is the professional configuration that produces gating with faster response and less tone coloration.
The best alternatives to the Boss NS-2 Noise Suppressor, ranked by tone similarity:
- ISP Decimator II — £179, 90% tone match. The professional standard at £100 more — the ISP Decimator II uses a tracking-based algorithm that monitors the dynamic envelope of the guitar signal rather than simply applying a threshold, producing a gate that sounds completely transparent even on fast picking and hard-gated rhythms. Players who notice the NS-2 slightly dulling the attack of their pick strokes or cutting off natural sustain too early find the Decimator II resolves both issues. It is the recommended upgrade path from the NS-2 for players who prioritise noise suppression quality over price.
- Fortin Zuul+ — £229, 88% tone match. Boutique high-gain gate at £150 more — the Fortin Zuul+ is specifically designed for high-gain metal rigs where aggressive noise suppression between palm mutes is essential. The Zuul+ uses a MOSFET-based circuit with a dedicated gate on the input to kill noise floor between notes while preserving attack transients on the downstroke. Compared to the NS-2, the Zuul+ gates with more aggressive precision on hard-muted metal rhythms; the NS-2 is the general-purpose noise gate, the Zuul+ is optimised for extreme high-gain applications.
- TC Electronic Sentry — £89, 85% tone match. TC's TonePrint-compatible gate at £10 more — the Sentry has an auto-sensing mode that automatically adjusts the gate threshold based on the detected noise floor, and a TonePrint slot for alternative gate curves. In direct comparison the Sentry's auto-sensing mode is often more effective on single-coil guitars that produce variable noise depending on position and proximity to lights; the NS-2's manual threshold is more consistent but requires setting. The Sentry is the modern replacement for the NS-2 for many working players.
- MXR Smart Gate — £109, 82% tone match. MXR's three-mode noise gate at £30 more — three independent gate types (Hiss, Mid, Full) that allow the user to match the gate character to the specific noise type being suppressed. The Smart Gate is the most frequently recommended upgrade from the NS-2: the three-mode approach is more nuanced than the NS-2's single-mode gate, particularly in Hiss mode which is optimised for single-coil guitar noise. Players who find the NS-2 colouring their tone or gating too aggressively on high-gain single-coil setups consistently prefer the Smart Gate.
- Electro-Harmonix Silencer — £59, 78% tone match. EHX's noise gate at £20 less — a similar threshold-based gate with a send/return loop for noise suppression of the processed signal in the same professional configuration as the NS-2. The Silencer's attack and release times are slightly faster than the NS-2, which produces a more abrupt gate closure that can be more obvious on sustaining notes. The NS-2's more gradual release curve is generally regarded as more musical; the Silencer is the alternative for players who want the same functionality at lower cost and accept the more abrupt gating character.
