If you buy pedals for instant inspiration, Walrus Audio’s Slö Multi Texture Reverb pedal was a real treat: one of the most – and we know this word is overused, but it is appropriate here – cinematic effects pedals we’ve ever tried. 

And the Slötvå is the Slö with three programmable onboard presets. A welcome addition because this pedal has bags of potential, and you’ll likely never settle on just one sound.
