The Glue is based on the legendary SSL bus compressor and makes a mighty fine job of performing transparent bus compression. Compared to similar plug‑ins, it’s more transparent but without sounding flat or boring. It’s kind of a ‘more of everything’ compressor, and at a great price too! It not only performed impeccably on bus‑compression duties, but was also able to tighten up bass guitar, acoustic guitar, drums and vocals without adding a ‘sound’.
