I love this compressor! It's so versatile. It has two compressor types - FET and Opto - and even a button to combine the two, making this unit a virtual "Swiss Army Knife."
The FET setting gives you a warm, rich sound with tons of "glue" and harmonics. This sound reminds me of Kings Of Leon, that's very dense and gluey. Great for bass or other low end material.
The Opto setting is more open - think "Explosions In The Sky." It also has more headroom than the FET, yielding a louder signal at the same settings. I use this option a lot for vocals, acoustic guitar or other mid range or high frequency material.
Other pluses about the GTC2 is the fact that you can choose to link both channels via the Stereo button, easily switch between FET and Opto, change the meters to show gain reduction or output, set the attack and release to auto or manual, bypass the compressor or disengage the electronics altogether. All of this, plus the Combine button on each channel allows for some interesting and useful tones and settings.
I've used this compressor on everything from miked sources and line signals, to putting it on the master buss. This is not another Neve clone!
I've owned the GTC2 and GTQ2 for a few years now. I also own a bunch of other high end gear including Neve 1073, Tube Tech CL1b, Manley Variable Mu, Avalon 737/747/2005, API 2500/5500, U87's, Sony C-800G, etc....
All this gear is great and has particular sounds that are excellent for certain situations. But, in overall quality, versatility, cost and customer service Aurora Audio is top notch!
The GTQ2 is just as good as the 1073 at considerably less money. The GTC2 is the most versatile compressor in my rack. It is my go to on many instruments, vocals and often mix buss. Fet, Opto and combination modes are awesome.
I've had the honor of meeting Geoff Tanner on several occasions at the shop. He's a genius! Him and Alan are true gentleman and make me feel like family. They have been very generous with their time and clever at resolving problems that were often the result of my studio setup. I've learned a lot from them and appreciate all their help!
