For ambient and atmosphere

The Slö is designed for texture: three reverb programs (dark, rise and dream) plus modulation and a sustain/freeze footswitch let you build huge, swelling, otherworldly soundscapes. The "rise" mode auto-swells each note for that synth-pad feel, and the freeze holds an infinite wash to play over.

It is less of an everyday spring reverb and more of a creative tool — but for ambient, post-rock and cinematic playing, it is one of the most inspiring pedals you can own.
