Everything you need to make a high-quality, professional recording is at your fingertips with the Tubesessor.
It's the ideal tube optical compressor when you need smooth, warm, natural dynamic control, but also the ability to spice things up every now and then.

Equipped with a TUBE SATURATION section, the Tubesessor allows you to add a touch of attitude with 4 settings ranging from CLASSIC, without saturation at all, to HOT, an angry sound ready to fight. This feature greatly expands the sonic options offered by the Tubesessor, making it far more flexible than any other tube-based optical compressor on the market.

Heritage Audio has also included its legendary sidechain filter section for even greater control, with five internal sidechain settings to choose from. These options help ensure the compressor isn't unfairly overloaded by low frequencies and offer three specific frequency settings for added creativity.

With infinitely adjustable ATTACK & RELEASE controls, as well as a FIXED mode and a combination of the two, the Tubesessor offers all the options needed to shape your signal exactly how you want it. Its huge custom VU meter ensures clear and precise monitoring of input, output or gain reduction, ensuring you're always informed of what's happening.
