“Overdrive, distortion and dirt that you have never heard before”: Keeley’s new 4-in-1 Series elevates the firm’s hybrid gain experiments – matching Rat, DS-1 BluesBreaker and Big Muff circuits to “Frankenstein new monster tones”

.

Keeley has expanded its stompbox arsenal with three new effects pedals that herald the formal arrival of its all-new 4-in-1 Series.

As the collection’s name implies, each pedal seeks to cram a quartet of overdrive and distortion flavors inspired by classic circuits and “brand new” gain tones into one single pedalboard-friendly package.
