how to get a nice gated reverb like one night in hackney

[loopdon]

You could put any number of effect like say chorus after or before the verb in mild doses, or a slow slow flanger added in slightly.

Should also give it that non-lin feel. The verb might sound different as well as the sounds before going into the verb could be changing ever so slightly. Either as a result of the source being an analog drum-machine or an emulation of one or because the samples aren't exactly the same on every beat...
