Marrow

Marrow is a multi-algorithm stereo digital delay offering six distinct voicings: Digital, Analog, Tremolo Delay, Chorus Delay, Chorus + Tremolo, and Filtered Delay. The delay time ranges from 10ms to 1 second for most algorithms, with Chorus-related modes spanning 10ms to 900ms.

The control set includes Regen (feedback), Mod, Mix, Divisions, and Dampen, with tap tempo for clock-locked timing. TRS 1/4" stereo I/O enables compact stereo setups without requiring dual cables. An external expression pedal input or internal ramp generator adds dynamic movement to the delay line, from subtle parameter shifts to extreme modulation.

As Neural Devices' second bestselling pedal after Chambers, Marrow stands out in the crowded delay market through its algorithm variety and stereo capabilities. The combination of standard delay functions with heavily modulated options makes it versatile for ambient, rhythm, and lead applications.
