Warm and smooth sound:
Classic reverb from Kjaerhus Audio is a great all round reverb.
Equally suited to create large halls for synths and strings, and very small rooms more suited for drums.
It offers a low cut filter to remove the low frequency rumble present in all reverb effects, and supports sampling rates up to 96kHz.
On top of this it comes with 33 presets and has a very low CPU usage.
