Created in close collaboration with Ian Martin Allison it delivers authoritative low end rich harmonic detail and a clear confident signal whether you?re playing live recording or practising at home.

Designed to sit at the end of your signal chain the Mantle combines musical gain a carefully tuned EQ and massive headroom in a compact pedal format. A transformer-balanced XLR output makes it equally at home feeding front of house or a recording interface while the unbalanced output lets you run an amp simultaneously.

Walrus Audio describes itself as a collective of artists, musicians and engineers, bringing circuit design together with distinctive pedal artwork. The company says its effects are hand-built and manufactured in the USA. JustPedals listings illustrate the variety: ARP-87 multi-function delay, Slö ambient reverb, Julia analog chorus and vibrato, and Polychrome flanger. Some models focus on direct, compact controls, while others provide broader modulation or atmospheric textures. Compare each model’s modes, stereo connections and control options; the artwork is a signature of the brand, while the circuit determines how it fits a rig.

Preamp & DI Pedals
A preamp brings an instrument signal to a controlled level and shapes its impedance, gain and frequency balance before amplification or recording. A DI converts the signal for a balanced, low-impedance connection and may include ground lift, pad and transformer isolation. Combined units can add drive, cabinet filtering, effects loops and parallel outputs while keeping the direct path stable.

Analogue
The signal is shaped by continuously varying electronic circuitry rather than being converted into a digital effect algorithm. Component choice, operating voltage and circuit tolerances influence headroom, noise, clipping texture and the small variations in response between designs.
Bass
Voiced or equipped to retain low-frequency fundamentals and the higher headroom of a bass signal. Clean blends, crossovers and bass-specific filter ranges can preserve weight and articulation while the effected portion adds harmonics, movement or ambience.
