Automatic gain compensation to maintain consistent levels as you adjust the drive control.

What Producers Say
Congrats to the ToneEmpire Team! This one sounds amazing. Sweet what it does to the transients and the stereo image. I tried it on the drum bus and the mix bus = instant Hi-Fi sound. Love it!
Sounds nice, the gain also is very close good work there. When gain match is just volume up and volume down the same amount it never really works, the scaling you have here is just perfect. Softube has a match system that requires u click a button and it takes second and matches the gain. but this is that much faster :-)
Ok now I have demoed this preamp on an electric guitar and I actually like it! A lot more presence and 3D.
