Using tremelo will make your tracks sound fatter and wider

thats one simple way of making things sit better in your tracks

Reverb used correctly has to be the best plug in ever invented (Especially Space Designer and Altiverb)

... I Just got my mixes sound even fatter by buying a Summing mixing bus by Audient with a Bus Compresor and Limiter. Its giving me lots more headroom and more ..... WIDE.. NESS ...

but for the amount of channels I have its expensive

hope this helps ..must dash
