The Marrow is a delay in compact design with enormous functions, it has 5 algorithms:

 * Digital (crystal clear)
 * Analog (dark & warm repeats)
 * Tremolo (delay + tremolo)
 * Chorus (dreamy repeats)
 * Chorus + tremolo (delay + chorus + tremolo)

 Soft switch bypass latch & momentary.
 Tap tempo (RAMP infinite sustain & modulation via SRM switch)
 Tempo divisions EXT jack (Tap Tempo & RAMP)
