Gated reverb cuts the snare reverb tail abruptly for the signature 80s drum sound

Gated reverb is the defining sound of 80s/Synthwave snares: a large reverb is applied to the snare, but its tail is cut off suddenly rather than allowed to decay naturally, leaving a short, explosive burst of ambience. Practically, it is created by running the reverb on a parallel channel (100% wet) and then shaping that channel’s volume — either with automation that drops the level to zero shortly after each hit, or with sidechain compression triggered by the snare. Applying the same gated-reverb settings to the claps as to the snare ties the drum kit together. Without gating, the same reverb sounds like a generic room; the abrupt cutoff is what reads as ‘Synthwave’.

Examples

Snare (dry) + parallel reverb channel (Voxengo OldSkoolVerb, 100% wet). Automate the reverb channel’s volume to fall to zero a fraction after each snare hit, or gate it with snare-triggered sidechain compression. Copy the same chain to the claps.

Assessment

Set up a snare with gated reverb using a parallel channel. A/B it against a natural reverb tail and describe the difference. Explain which control (automation vs sidechain) creates the abrupt cutoff.
