Magma StressBox

Magma StressBox

Shape musical tension & feel – with one knob

Flat, lifeless source holding your mix back?

It’s a common struggle: tracks that lack a sense of drama and emotional lift. You try EQ, compression, saturation – but the feel still doesn’t translate.

Enter the StressBox – a dynamics tool that shapes musical tension.

• Turn right for aggressive compression that pulls the room sound forward and slams you with urgency and in-your-face energy.
• Turn left for expansion that enhances transients, shortens reverb tails, and wraps your track in a tighter, controlled feel.

Dial in Emotion

A single knob shapes your track’s emotion – from intimate expansion to explosive compression. Each turn uncovers new character, on any source you place it on.

Automate the Feel

Ride energy and emotion with automation – create lift, movement, and contrast between verses and choruses.
