The way bx_clipper drives mixes is so much better than most saturation / clipping plugins I've heard in the past. It's a hell of an addition to any master chain before the final limiting process!
SPL BiG definitely lives up to its name! I was already a fan of the hardware unit due to its innovative way of enhancing the stereo field, and it had me wishing for a plugin version for a long time: I'm glad that Brainworx made it happen for us!
