Optical compressors have a particular way of responding to the incoming signal that is uniquely compelling and musical. But they are of course not all the same, and the Tube-Tech CL 1B is the prime example of what an optic compressor is capable of. It is highly versatile and can go from soft and gentle to snappy and punchy by the twist of a few knobs.

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.

To me it's the closest representation I've heard of any hardware ever. Fantastic.

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.

In Short

  • Versatile but still a bucketful of character
  • Optical compressor with a vacuum tube gain stage
  • Created together with the designers at Tube-Tech
  • Each and every component carefully modeled
  • External sidechain control
  • A seriously great looking GUI!

A truly faithful and very exact replica of the hardware CL 1B. Finally it's possible to experience natural musical compression in a plug-in.

The CL 1B is a true compressor for all seasons. I found it perfect for any individual track from bass to vocals to drums because it is precisely adjustable and able operate perfectly for any kind of dynamic control from transparent and subtle to more typical compression chores with 2 to 6dB of peak compression and then all the way to major audio clamping with a striking, and colorful character. It's a big winner for me and is a major player in all my mixes from now on!

Tube-Tech CL 1B is a great all-round compressor that works in many situations and it acts how I predict it will, no matter how hard I drive it.

There are barely words to describe what I think about the CL 1B plugin. The sonics are outstanding. The GUI is awesome. I thought it was just a picture until I started turning the knobs. I own hundreds and hundreds of plugins but... the CL1B plugin is the most accurate representation of a hardware that I have EVER seen.

The CL-1B is now my first choice software compressor. I absolutely love it on vocals. But it also adds that special Tube-Tech warmth to bass, synths and drum busses.

Tube-Tech CL 1B is by far the best vocal compressor I have ever heard. It's extremely smooth yet controlling, and it can be found on the lead vocals in 90% of all my mixing sessions.

Softube first came onto my radar through the Tube-Tech CL 1B. I used the original hardware a lot during tracking and found the plug-in to be a great software version of it.

Overall, the CL 1B really is a fantastic compressor plug-in that's capable of both subtle containment and excellent audible colour.

One of the warmest, natural and most musical compressors I've ever heard. Buy it.

... I spent hours going through settings hardware vs software and I just kept saying 'this is unbelievable'.
