Echo. Kosko Series

A lo-fi delay with warm analog character and soft, gradually fading repeats.
Built around the classic Deep Blue Delay–style circuit using the PT2399 chip, it delivers a recognizable tone with subtle vintage coloration. The repeats decay smoothly, creating a textured, slightly dirty ambience that sits beautifully behind your core sound.
With Time, Echo, and Mix controls, you can precisely shape delay time, feedback intensity, and wet/dry balance. The Mix knob allows you to blend the effect seamlessly into your signal chain without sacrificing clarity or articulation of the dry tone.
Perfect for shoegaze, psychedelia, and any style that calls for gritty, modulated echo textures with character and depth.
