I just bought and tried out a BOSS NS-2 noise suppressor and it was a fail for the rig I am trying to set up. When engaged, the signal dropped markedly. When used with a BOSS MT-2, in the NS-2 internal loop, directly into the FX return, the signal dropped further and then rose as a chord was sustained. The gate was slow to close. I am going to trade it in against a different noise gate. I am leaning towards a TC Electronic Sentry. Any experience of the Sentry, or other recommendations for a UK resident?
