A beautiful EQ, but the high-pass and low-pass filters are what really blow my mind. Some of you know how near and dear the UAD HLF plugin has been for me in stem mastering. The filters in Combox are easily as useful, offer a different texture, and are continuous instead of fixed intervals. Sometimes HLF is too heavy handed, enter Combox instead. Truly great high/low-pass filter plus EQ.
