The MXR M-113 Digital Delay is a 2-space rackmount digital delay, made by MXR. It belongs to the company's rackmount era: Dunlop, which owns MXR, describes a line that "began with 2-space rack units such as the M-113 Digital Delay"1. Rather than sitting on a pedalboard, a unit like this lives in a rack, controlled from its front panel and patched into the effects loop or the signal chain like any other outboard delay.

What it does
As a digital delay, the M-113 stores your signal and plays it back after a set time, producing repeats of what you play.
Where it sits in MXR's delay history
The M-113 is the starting point of MXR's delay line as Dunlop tells it. From those rack units, MXR later moved into pedals, and the company's current delay range is built around the Carbon Copy family of analog delays, along with digital designs such as the MXR M299 and the stereo MXR M309 Joshua Ambient Echo, which MXR describes as capturing classic rack studio delay tones1.
Players looking at the M-113 today are looking at the rack-era ancestor of that pedal line. Related units from the same era and lineage include1:
- MXR M-118 Analog Delay, the rack-era analog companion1
- MXR Model 113 Digital Delay, a later compact unit carrying a similar model number1
The M-113 is a rack unit, not a stompbox: it takes rack space rather than pedalboard space, and it is a product of MXR's rackmount era rather than the company's current pedal line1.
