1) Precision Multiband by Universal Audio
This is a specialised mastering tool, essentially a multi-band dynamics tool. It provides five spectral bands of dynamic range control. Compression, expand, or gate can be chosen separately for each of the five bands
It’s great for finalising a mix with some multi-band compression, really fattening up a mix and providing multi-band glue which gets things popping and bouncing! I love the control you get with this plugin, it really feels top class.
2) The Glue by Cytomic
This really gels mixes together, and it does exactly what it says on the tin, it glues! It’s based on an 80’s console buss compressor and provides a mix energy that really suits modern music.
It’s a cheap plug-in too and often finds its way onto the master channel for that little extra mix energy. It can be used subtly or to pump a track a bit harder. Try slapping it on your mix for a bit of glue!
3) SSL G-Master Buss Compressor
The original Solid State Logic hardware unit of the much renowned G-Master Buss Compressor was lovingly programmed into a plugin by Waves, and it really adds an extra pressurised energy into drum mixes and kicks.
It adds weight and fatness by glueing and controlling the transients and colours a buss subtly with warm compression. It's world renowned for a reason!
4) Valhalla Vintage Reverb
This really is an underrated but beautiful reverb that adds rich textures which have just enough shimmer and warmth. It’s a less known plugin but is still used by Grammy winning productions, most famously recently on Adelle’s ‘Hello’.
Don’t be fooled by its vintage label, this has a place in any mix and provides warmth, space and depth to instruments and percussion.
5) Cambridge EQ
This is simply one of the best EQs on the market and is renowned worldwide for its ability to add finishing touches to masters as well as tonally shaping and cleaning up audio tracks of any source.
I love its precision and its reliability, it cut out unwanted frequencies cleanly and easily.
