Frequently Asked Questions

The Hard Knee setting provides a more abrupt transition into compression, while Soft Knee offers a smoother, more gradual response.
The Auto mode is surprisingly effective, intelligently adjusting attack and release based on the input signal, offering a great starting point and usable sound without deep tweaking.
The Pro offers significantly more control and versatility than the Raditor, and while the Chameleon is more focused on specific amp voicings, the Pro is a more general-purpose, transparent compression solution.
