Just like Valhalla, Cytomic's plugins are fixed at their asking price. I was thinking it would go on sale on Black Friday/Cyber Monday, but it did not. This perhaps makes it sound a bit 'tighter,' more glue-like? At this time,I have only demo'ed it, but will buy it soon. All things being equal, the Glue delivers a bit more gain reduction at the same values when compared to the PC4K. It may be related to the threshold and gain-reduction differences between the two I don't know for sure. The PC4K's release times are a little funky when compared to the Glue. To my ears, the PC4K seems slow and sloppy. For me, however, overall I think the Glue fairs better 'musically' than the PC4K bus comp, especially when sidechaining. If the OP is still out there, perhaps he can chime in with some thoughts in regards to the comparison.

+1 ^^^^ Always was curious how Sonar's 4K Buss Comp fairs in comparison? I use the 4K a lot and like how it sounds with small amounts of GR on the mix buss. There's a massive thread over on Gearslutz on this thing - rave reviews (and how I found about it): B

Right now I use my Portico 5043 into this thing into my UAD Precision Limiter on my 2-buss and could not be happier with the results. I'm in NO WAY affiliated with these guys - just a mega/super fan after running a few of my mixes through this thing. Trust me, I don't care how many compressors you have - this is one you want in your arsenal. I demo'd the UAD Buss Comp (also modeled after the SSL buss comp) and it didn't blow me away so I never bought it. I bought the Waves SSL bundle a while back and was just never impressed with the compressor - it's compression characterstics are nice but it kills the stereo image. It's modeled after the SSL 4000 but IMHO (and many others), absolutely blows away the Waves SSL. For a 2-buss compressor this thing is stunning - blows the doors of the Waves SSL stuff and it's not even close. I have just about every ITB compressor you can think of - Waves SSL, API, Chandler/EMI, UAD, Stillwell, etc.

If you haven't had a chance to mess with this thing - GET IT!!! Cytomic 'The Glue' VST - Best ITB Compressor I've Ever Used!
