    HOT, an angry tone ready for a fight. This greatly increases the tonal options you can achieve with the TUBESESSOR therefore making it much more flexible than any other optical tube compressor out there.  This takes full advantage of a creamy sounding NOS Raytheon double triode tube to add in just a pinch of aggression or fully transform the signal into something ready for war.

    9- RELEASE: Continuously variable from 0.05 to 10 seconds. 10- SC FILTER: This is a filter applied only to the control signal to decide if and where the TUBESESSOR will be less or more sensitive to certain frequencies. There are 5 choices available: 80, 160, 1K, 3K and 5K. The first two settings are great to avoid the compressor being unnecessarily overpowered by lower frequencies, very useful to avoid undesired pumping.
