Collision Devices Crushturnal

A Collision Devices Ambient Pedal Designed to Go Beyond Classic Shimmer

The Crushturnal fits within Collision Devices' "ambient" and experimental approach: creating expressive, rich, and sometimes unpredictable effects capable of dressing a guitar, synth, or studio source. Its Ambience section captures the spirit of a bright reverb with cascading pitch inspired by shimmer, while the Digital Repeater pushes digital delay toward sample manipulation and resolution reduction. The whole is centered around a common clock, then animated by a sequencer that transforms clock speed into musical variations.

For Which Musicians and Uses?

The Collision Devices Crushturnal is aimed at guitarists and texture creators who enjoy sculpting space: post-rock, ambient, shoegaze, drone, film music, experimental electronic, as well as any situation where a delay/reverb becomes a full-fledged instrument. Live, it excels at building pads, breathing life into a theme, or creating spectacular transitions between songs. In the studio, it becomes a sound design tool: you can freeze a sense of movement, dirty an echo with a lo-fi aesthetic, or generate unstable rhythmic patterns thanks to the sequencer.

Regarding skill level, it suits both intermediate musicians (looking for an inspiring and immediate pedal) and advanced users (seeking limit zones, self-oscillation, granular textures, and fast modulations). If you like pedals that respond to playing and settings, and can shift from ethereal to "broken," the Crushturnal clearly fits this philosophy.

Controls, Sections, and Interactions: An Architecture Built for Exploration

Ambience (white controls) is a cathedral-type reverb with a bright and expressive character, enriched with cascading pitch effects. It offers FX Level (reverb volume), Diffusion (release and density of the tail), and Filter (cutoff frequency of a low-pass filter to soften or brighten the high end).

Digital Repeater (gray controls) combines digital delay and sample manipulation. The idea: a "robotic" sounding repeater where each repetition can be sampled then "reduced" to achieve a rawer, more granular, or intentionally degraded texture. Controls include FX Level (delay volume and sample rate action), Time (time between repetitions), Feedback (number of repeats), Sample Rate (sample rate of the sample reducer), and Crush (mix of delay and dry signal, then sent to the sample reducer).

The heart of the instrument is the large Clock knob (orange): it controls the processor's clock and influences both the length of the reverb and delay, as well as behavior related to sample rate. Result: a single gesture can shift from a spacious and clean environment to a more unstable, textured world, with a sense of "pitch" and transformation linked to clock changes.

Sequencer (orange controls) adds a step dimension to the Clock control. It simulates clock movement according to selected musical intervals and rate, allowing rhythmic and harmonic variations. Rate sets the sequencer speed (from 2 seconds to 5 milliseconds), with the possibility at high speed to introduce behaviors close to ring modulation. Step Size adjusts the amplitude of the step intervals: each new step abruptly changes the processor frequencies by multiplying the clock control frequency, generating a musical interval. Mode determines direction and number of steps through different modes, producing more or less predictable cycles.

To integrate the Crushturnal into a modern pedalboard or creative setup, the sequencer section also offers control tools: CV/Exp input to control the clock, CV output to control other devices, tap tempo, and Sync input to set the speed. This allows synchronizing your textures, locking a groove, or conversely provoking perfectly intentional creative slips.

Sound

The Crushturnal has a decidedly ambient and cinematic personality: the Ambience reverb evokes large spaces, with a "celestial" brightness and pitch cascades adding a harmonic dimension. The Digital Repeater provides contrast: a digital delay capable of remaining clear but especially transforming into lo-fi material thanks to sample reduction and sample rate settings. Combining both yields reverb tails that seem to sing, repetitions that fragment, and pads that can become moving, granular, or intentionally "crushed."

The dynamic is ideal for expressive playing: adjusting Filter, Sample Rate, and Clock shifts from a soft, enveloping sound to a more abrasive, "degraded digital" aesthetic. The sequencer adds a sense of a living effect: stair-step pitch and texture variations, looping patterns, and extreme accelerations flirting with metallic textures and radical modulations.
