More information about the noise gate
- Cliff: "I don't use the gate at all. On the Ultra I would use the gate on high gain patches but I find I don't need it now. I did some measurements and the II is at least 10 dB better SNR." Source
- Firmware 5 release notes: "New gate uses dynamic filtering in addition to downward expansion."
- Wikipedia
Settings and parameters
- The Input Noise Gate on the II works different than on the Standard/Ultra. Adjusting Threshold won't do anything if Ratio isn't adjusted as well.
- Cliff (firmware 10): "I DID change the default attack time. For a guitar gate you typically want the attack time as short as possible and I don't think people realize this so I changed the default value." Source
- Firmware 11 and later have made it possible to save noise gate settings as global blocks.
Level
- Firmware 11: "Added Level parameter to Noise Gate. This allows sending a lower or higher level into the effects grid which can be used to compensate for guitars with varying output."
CPU utilization
- The Noise Gate uses CPU cycles, so switch it off (turn Threshold to Off) if you have no need for it in a preset.
Gate/Expander alternative
- The Axe-Fx II has additional noise gate blocks: Gate/Expander (block).
Alternative: use a Vol block
- A different approach to keeping the noise low: try a Vol block with the volume parameter tied to the Envelope controller. As long as you don't hit the strings, the (input) signal is off.
