Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about TUBE-TECH CL-1B.

Comparisons

  • Kiive emulation is noted for its versatility and is perceived by some users as sounding closer to the original CL-1B than the UAD version.

    Source
  • Compared to the LA-2A, the CL-1B is noted to be faster, which is beneficial for capturing quick transients in genres like rap.

    Source
  • The Softube CL1B plugin is noted to closely emulate the hardware version, particularly when compared to other plugins like the UAD, which uses the same Softube code.

    Source
  • Softube's CL1B v1, while close to the original hardware, is noted to lack the hardware's "lift" and saturation characteristics, requiring users to adjust their processing approach.

    Source

Software and compatibility

  • Issues with UA Connect include forced auto-updates that may disrupt plugin functionality if they conflict with the operating system, requiring internet for operation.

    Source
  • UA's DSP-based CL-1B is essentially a Softube emulation, highlighting the distinction between UAD's platform and native plugin availability.

    Source
  • Users suggest that the Softube CL1B MKII is an excellent native plugin choice, with some indicating that UAD's delay in adopting MKII demonstrates its quality.

    Source

Use cases and applications

  • The UAD CL-1B is appreciated for its smooth compression, particularly effective on vocal tracks, though some users prefer it for adding a "smear" effect on acoustic buses.

    Source
  • The CL-1B is favored for its transparency and is frequently used on vocals and bass, though some users also apply it successfully to acoustic guitars and percussion.

    Source
  • The compressor is popular in Nashville studios for country vocals, although some users find it less forgiving with dynamic singers, requiring careful management of the threshold.

    Source
  • The CL-1B's tube design subtly smoothens the low and top end, making it especially appealing for vocal work where a natural, transparent sound is desired.

    Source
  • The CL1B is praised for its ability to soften transients without losing clarity, making it suitable for preserving the "air" in vocal recordings.

    Source
  • For achieving CL1B-like results, combining a plugin with high-frequency saturation or a de-esser is recommended to mimic the hardware's analog warmth.

    Source

Features and functionality

  • The CL-1B offers more control with its additional parameters compared to the LA-2A, making it a versatile choice for those who want less character from their compressor.

    Source

User experience

  • Owners report a learning curve with the attack knob, cautioning that small adjustments can significantly impact the sound, but achieving the right settings yields exceptional results.

    Source

"The Shure SM58 is the preferred microphone for his vocals for its grittiness, run through the 1081 into a Tube-Tech CL 1B with low compression ratios to even everything out." (While the engineer is providing this feedback, the gear is housed in Marr's own Crazy Face studios, which contains gear he's collected over his decades in the music industry.)

The dynamics processor that has been used for Kanye's vocals throughout the recording as well as for all his live performances is the Tube-Tech CL-1B.

We are very pleased to have an artist of this importance on our users list - and much more so because Mr. West normally doesn't want to have his name connected to any specific piece of gear. In this case, however, he has agreed, and, in all modesty, we see that as a very important recognition of the Tube-Tech sound.

Kanye West’s sound engineer is Noah Goldstein, who got the gig only 6 years after graduating from Temple University in Philadelphia, working in Electric Lady Studios with artists such as Arcade Fire, Steve Earle, Katy Perry and Danish act Kashmir in the meantime. Noah is responsible for all Kanye's vocal recordings and for a main part of the mixing and organizing Kanye's tracks for his records, as well as for live use.

Used for Albarn's vocals on Gorillaz's "Charger", as mentioned by recording engineer Stephen Sedgwick in this July 2017 Sound on Sound interview about the production of Humanz.

“I recorded Damon’s rough vocals with a Neumann KMS105 condenser, which sounds pretty good and doesn’t pick up a lot of sound from the room, so it works great if there are other people around and he quickly wants to lay down some ideas. But when it came to recording his final vocal takes I used the Flea 47, which is a really great-sounding Neumann U47 clone. I usually recorded it via a Chandler LTD1 mic pre, and then either a Distressor or a Tube-Tech CL1B compressor."
