The new look of the CL1B plugin brings together an attractive, yet functional interface, with a few tweaks. It's still clearly a Tube-Tech unit, but now contains many of the features of their current (and most popular) CL1 compressor plugin. It's a clean and even-handed image compressor that will work very well as the centerpiece of your mix.
The CL1B is available in three different models. There is the basic CL1B compressor (Single-band compressor only, with 10 dB of dynamic compression), the CL1B-D (Dual-band compressor with 3 dB of dynamic compression) and the CL1B-R (Random mode only, the ECN of this mode is the -8.5 dBFS).
The Tube-Tech CL1B Collection is a suite of plugins designed to emulate the vintage-sounding tone and dynamics of the CL1 compressor from the 1970's. If you're looking for a truly authentic compressor plugin, I highly recommend Tube-Tech's CL1B collection of plugins. It's not only free of digital artifacts, it's emulated by the Tudor Venom tube amp and the 24AX7 tubes, native to the Harrison mixing console.
