T-Tech CL1BB Optical Compressor
Smooth control. Modern clarity. Musical dynamics.
The CL1BB is not about vintage coloration — it’s about refined control.
Its optical compression design delivers smooth, transparent gain reduction with precise handling of dynamics, making it ideal for vocals, bass, and detailed mix work.

How it behaves
- Compression is smooth and highly controlled
- Dynamics are shaped without losing clarity
- Response remains musical across a wide range of material
Audio Demo
Compare the original hardware signal and the NAM profile across a range of sources — bass, guitar, synth, and more.
Each example demonstrates how closely the profile captures the tone, dynamics, and harmonic response of the hardware.
The NAM and hardware samples are gain-matched to allow for a more accurate evaluation of the capture’s fidelity.
For additional context, a dry (unprocessed) version is also included.
Why this capture is different
- Multiple application-focused compression styles
- Precise gain reduction calibration
- Optimized for vocals, bass, and modern mixes
Waveform Comparison (Hardware vs NAM)
Below is a direct comparison between the original hardware signal and the NAM profile output.
This visualization highlights how accurately the dynamics and response are preserved.
Technical notes
- Format: NAM (.nam)
- Sample Rate: 48kHz
- Capture Type: Real hardware
- Calibration: Studio-level gain staging
Gain Staging Advice
Our captures are pre-calibrated at -18 dBFS input level.
For best results, we recommend feeding the plugin with an input signal close to -18 dBFS.
Due to gain reduction during the profiling process, the output level of a loaded profile may be slightly lower than the original input signal.
Please adjust the Output control to match your source level or to reach your preferred listening volume.

Honestly, I’ve tried pretty much every CL1B plugin out there, but this is the first time I’ve felt that actual hardware ‘bounce’ in the box. It’s got that creamy tube warmth that just makes vocals sit perfectly without sounding processed. If you’re chasing the real deal, this is it.
