The Classic Delay emulates three of the most commonly used delays / echo sounds types: Tape, Analog, and Digital, but without the introduction of noise. A quality control is included where the sound of the echo machine can be adjusted to give the preferred amount of “imperfection”. The delay can be synchronised to the host, and the feedback can be reversed to give a ping-pong effect.

Tips

1. The tape delay type gives you the sound of echo being degraded slightly each time it is fed-back and re-recorded. You can adjust the quality control for the amount of flutter and distortion introduced.

2. The analog delay type has a very "dark" sound due to the low sampling rate and sharp filters used to save analog memory. The "darkness" of the sound can be adjusted via the quality control, which emulates the changing of the sample rate.

3. The digital delay can be adjusted from bright and clean on the highest quality setting, to a “darker” and more noisy / distorted sound if the quality setting is set low. This enables you to emulate the sound of older digital delays with less bit depth and a lower sample rate.

Updated versions of all their other free 'Classic' plugs are also available.

Those are great plug-ins. There are tons of free plugs available, few are classier than the KJAERHUS. The reverb one is crappy, though.. IMHO. It's subjective, but there are plenty of freeware reverbs on the same level, IMHO.

I had just about every freeware plug imaginable installed and I deleted 90% of them because my sequencer was taking 5 frickin' minutes to load on a 2.8ghz machine!

Yep they are rather nice plugins.
I managed to use the reverb with a short tail for some overdrive guitar. Worked better than SIR.
The delay looks very intuitive, I hate the Steinberg delays for their GUI.
Finally the Kjærhus plugins use linear mouse movement
