From Great River Electronics

The new PWM-501 employs some fairly mythical options, offering the engineer tons of ways to shape signal, on everything from tracking individual elements, stereo mic setups, all the way to the stereo mix bus.
The compression range and palette of sounds that can be found with the 501 is virtually infinite. With its Feed-Forward and Feed-Back Control, you have two completely different sounding compressors. If you need aggressive transient shaping for drums and percussion instruments, just dial in your desired amount of compression with Feed-Forward mode. Or use Feedback mode for a seriously round and warm response on things like drum overheads, bass and vocals. You can dial in the perfect amount of glue for anything you want. It is a sweetly enhancing sound, that is well suited for all-duty workhorse compression.
