Tube-Tech CL 1B is one of those units that has a defined personality while still being useful on a variety of sound sources in a variety of situations. It can be used for a calm and natural dynamic control, but depending on your settings, it can bring out punch and life from any material. Because of its way of treating the signal differently depending on the frequency content, it gets a lot of love when used on material with a wide frequency range, such as an electric bass that both needs low end control and a snappy presence, or an acoustic guitar that needs to be large sounding and close to the listener. And sometimes, the opto character is just what the doctor ordered for a full mix.
A big part of the CL 1B sound is that the optical gain reduction circuit has a tendency of an initial very quick release time, which then drastically slows down and can take several seconds to fully recover. This has a way of giving a transparent control of shorter events in the signal while retaining a grip of the overall material. It's a sound and texture you will not find in any other compressor.
The Tube-Tech CL 1B Compressor is also available in the Tube-Tech Classic Channel bundle, together with the famous Tube-Tech PE 1C "Pultec" Equalizer and Tube-Tech ME 1B Mid-Range Equalizer equalizers.
