The preferred vocal compressor for pop, hip‑hop, and R&B.

Developed by Softube, the Tube-Tech CL 1B MkII plug-in for UAD hardware and UA Audio Interfaces is an update of this iconic optical compressor used by modern artists like Kanye West, Rihanna, Jennifer Lopez, and more.

Featuring numerous sonic enhancements and new high-resolution graphics, the Tube-Tech CL 1B MkII plug-in has been reimagined with Softube's latest component modeling and signal processing technology, for an even deeper emulation than before — capturing this modern classic in all its tube glory.

Track and mix with an updated emulation of a modern classic compressor, fully endorsed by Tube-Tech, Denmark

Enhance transients and retain dynamics with new Parallel Compression and Sidechain Low Cut controls

Add musical-sounding compression to vocals with the same “go-to” unit preferred by Kanye West, Rihanna, and Jennifer Lopez

Dial-up weight and tube character on drums, bass, acoustic guitars, and vocals

A Modern Opto

A Modern Opto

A studio staple across a variety of genres, the Tube Tech CL 1B takes the classic warm opto compression recipe and modernizes it with selectable Fixed, Manual, or Fix/Man attack and release settings, making it useful on myriad sources. From soft and gentle massaging of a vocal to accentuating punch and snap on drums or guitars, the CL 1B's vintage/modern approach to dynamics control make it a go-to compressor for pop royalty.

Added Versatility

Added Versatility

The new Parallel Compression control lets you easily blend in compression on a drum loop or lead vocal, while the added Low Cut Sidechain feature keeps your sources punchy by keeping greedy low end away from your compression threshold.

Game changer !!!!

Since the purchase of Tube-Tech Cl 1B I have not put it down . It’s literally on every mix I do which is in the genre of Hip Hop . The color and texture it adds to elements is hands down the best in my experience. Don’t get me wrong different elements require a different approach and depending on what your aiming for but this compressor fits a lot of the elements I work with. You won’t go wrong with this tool .

I wish I had read the reviews before purchasing. Very buggy, all the issues listed by others are still a problem.

Still not working

I Do not recommend to buy it until they fix it
It's Disappointing, considering the price and how long this has been a known problem. Currently it's not working properly ...

Glitch ridden. VU meter jumps. Crashes LUNA.

I don't understand how this issue can be unresolved for so long. Bizarre.

Still not working

I can understand that both UAD and Softube are having to collaborate to get this plug-in up and running, causing delays. Fingers crossed it gets sorted soon. Until then, I don’t recommend purchasing unless you don’t mind downgrading your software to 9.14.5

MkII Glitches

The MKII Version is malfunctioning on my m1 Mac mini...It works for a while then stops transmitting sound...this has been going on even after upgrading to version 10

VU bugged out for months

I think this plugin would sound amazing, if it would actually work properly. The bugs around this Plugin have been known to UA for months now, but still no fix in sight. I really hope this gets addressed soon because it is one of my favourite compressors for vocals.

Lovely sound

I really love the sound of this compressor especially with hip hop and neo soul or anything that needs more body! Adds nice thickness and glue

Don’t put this on your chain till they fix it

If you throw this on your chain you could be introducing yourself to a ton of issues if not immediately the worst…. Later!!!!! Don’t bounce down with it… will mute the track it’s inserted on

The METER doesn't work in LUNA, you have to pull the plugin up in console to see how much GR, then it jumps around and never goes to 0. This plugin also locks up whatever sessions I have it on after updating to the new software and I have to restart my computer to even reopen luna to open another session. I now have ANY access to ~90% of my sessions and UA isn't responding to anything regarding this plugin and its bugs !!!!

Very Disappointing

Really wanted this to work. but it doesn't, pumps badly anything over -3 db GR at any setting. And obviously the needle jumps all over the place. Wasted money. please can we have a fix.

Worthless plugins it only does harm to every project

Restarted my laptop about 50 times before the mk ii worked, coming to find out that it crashes the whole Luna and Apollo system. Every export Will Result into cracking issues so simply said, you can never bounce a normal project.
