The key to using reverb in EDM is to apply it in a way that enhances the energy and dynamics of the track without causing muddiness or loss of clarity.
Always consider the context of the mix and the role each element plays within it. Adjusting the pre-delay, decay time, and EQ within the reverb can help to ensure that it adds to the track effectively without overpowering the primary elements.
Synth Pads: Reverb can be applied to synth pads to create a sense of depth and space, making them feel larger and more atmospheric.
Leads: A small amount of reverb on lead synths can help them stand out in the mix without clashing with other elements.
Vocals: Reverb is often used on vocals to give them space in the mix and to add a professional sheen. It's important to use it sparingly to avoid washing out the clarity of the lyrics.
Snare Drums: A moderate reverb on snares can give them more presence and a sense of space in the mix, often used to enhance the impact on the second and fourth beats in a bar.
Hi-Hats and Cymbals: Light reverb can add shimmer and sustain to these high-frequency elements, but it should be used carefully to avoid muddiness.
Kicks: Usually, kicks are kept dry in EDM to maintain their punchiness, but a subtle touch of reverb can sometimes be used to add depth, particularly for softer kick sounds in genres like deep house.
Basslines: Generally, reverb is used very sparingly on basslines because it can quickly muddy the mix. However, a touch of reverb on a higher-frequency bass synth stab or pluck can help it gel with other melodic elements.
Stabs and Chords: Short, bright reverbs can make stabs and chord hits more impactful and help them to decay naturally into the mix.
Effects and Transitions: Reverb is often used on risers, downlifters, and other transitional effects to build tension and smooth transitions between sections of the track.
Percussive Elements and Drum Fills: Adding reverb to these elements can create a sense of unity and space, helping to tie together individual drum hits into a cohesive rhythmic section.
