Tube-Tech CL 1B – Iconic Opto Compressor – Studio Standard – Excellent Condition

THIS IS THE HOLY GRAIL.. VINTAGE GREY TRANSFORMER!!!!!
Do not fall for blue or black transformer versions, they sound inferior.

Up for sale is a Tube-Tech CL 1B, the legendary tube-driven optical compressor that has become a modern studio staple — especially beloved for vocals, bass, and anything that needs smooth, musical dynamic control.

This unit is in excellent condition, fully functional, and has been carefully maintained in a professional, smoke-free studio. Cosmetically clean, with only minimal signs of rack wear. 

Why the CL 1B Stands Out:

• Tube-based opto compression: warm, smooth, and incredibly musical
• Incredibly popular on hip-hop, pop, and R&B vocals – used by artists like Drake, Beyoncé, Travis Scott, and more
• Full control over attack, release, ratio, threshold, and makeup gain
• Easy to dial in — whether you’re after transparent leveling or colorful compression
• Handbuilt in Denmark with high-end components and premium craftsmanship

Specs:

• Input and output transformers for classic analog tone
• Switchable manual or fixed attack/release settings
• Balanced XLR in/out
• 2U rackmount chassis
  

If you’re looking to add a world-class vocal compressor to your signal chain, the CL 1B is it — silky, present, and full of character.
