This is a nice double chorus sound that is remeniscient of 90s/80s. It is very liquid and subtle. The trick here is using a very short pre-delay to put it slightly out of phase. Having two choruses won't overload or destroy the sound if you use these settings in an effects chain.
Signal---->Chorus 1--->Chorus 2---->Out
Signal---->Predelay 1-->Chorus 1
Signal---->Predelay 2--->Chorus 2
(turn down levels)
5.10 hz chorus rate (Fast)
36% Depth. This means that the effect should be subtle
0.5ms Pre-delay This second delay is slightly longer but is still out of phase with everything, including the main mix
0.70 hz chorus rate (SLOW)
This setup sounds good with strings and leads.
