My approach to compression and The Glue is very different than the first two reviewers. My experience with finalizing a mix is limited. My comfort zone was always with playing music and my old musician ears are losing the detail that makes me comfortable mixing. What I need is a compressor for idiots and with a light touch The Glue does that very well. On the final bus and with a light touch it does bring the mix together.
I have a few of the compressors available in the UA system. The Glue is half the price, not bound to hardware and both competes and compliments the UA compressors. It may be a bit early but right now I would call The Glue the must have compressor for any budget. It is nice that most any budget can afford it.
