The Old Blood Noise Endeavors MAW is a vocal effects pedal built to sit at the center of a singer's setup. The maker describes it as "a suite of effects designed to be your all-in-one vocal effector," combining saturation, two effects banks, and a send/return to add your own effects1. Its effects include reverbs, delays, modulations, and pitch shifting, so it covers ground players usually associate with reverb, delay, chorus and octave & pitch pedals in a single unit1. It belongs to the broader family of multi-effects pedals and vocal pedals.
Inputs, outputs and the send/return
The MAW is built around XLR connections. It takes XLR or 1/4" in and out, and the XLR input has a Mic Level and Pad switch to set the incoming level for a microphone1. An Output Select control chooses between XLR or 1/4" out, so the pedal can feed a mixer or an amp1. There is also a dry XLR out to send the unaffected signal separately, useful for splitting a voice between a processed and an unprocessed path1.
The send/return loop is the third part of the signal path: it lets you add your own effects between the MAW's own processing, so the saturation and the two effects banks can be combined with pedals you already own1.
Controls and footswitches
The pedal carries three independent footswitches, one for each part of the engine1:
- Saturation: Volume, Blend, and Tone controls1
- Effect A and Effect B banks: CTL1, CTL2, Mix, and a 5-way selector to choose the effect and control its parameters, for both A and B1
- Footswitches: Independent switching for Saturation, Effect A, and Effect B1
The two effects banks work side by side, each with its own 5-way selector, so two different effects from the reverb, delay, modulation and pitch shifting set can run at once, each with two assignable control knobs and a mix1.
The MAW requires a 9V DC center negative 2.1mm jack power supply capable of 210mA, and the supply is not included1. Its draw is higher than many single pedals, so a supply output rated for at least 210mA is needed.
Expression control
The MAW has expression jacks to externally manipulate one knob each of both A and B1. With two expression pedals, a player can sweep one parameter in each effects bank at the same time, for example riding a delay's control while swelling a reverb's.

Questions
Is the Old Blood Noise Endeavors MAW only for vocals?
Old Blood Noise Endeavors describes the MAW as a suite of effects designed to be your all-in-one vocal effector, so vocals are its intended use. It accepts XLR or quarter-inch inputs and outputs, so a guitar or other line-level source can be run through it as well. The effects on board include reverbs, delays, modulations and pitch shifting, which work on any signal fed into it.
Does the MAW take XLR microphones?
Yes. The MAW has XLR or quarter-inch inputs and outputs, and the XLR input has a Mic Level and Pad switch to set the incoming signal level. There is also an Output Select control to choose between XLR or quarter-inch output, and a separate dry XLR output for sending the unaffected signal elsewhere.
What power supply does the MAW need?
The MAW requires a 9V DC center negative power supply with a 2.1mm jack, capable of supplying 210mA. The power supply is not included. Because of the 210mA draw, a standard low-current daisy-chain output may not be enough; a supply rated for at least 210mA is needed.
Does the MAW have trails?
Yes. The MAW uses soft-touch footswitches with buffered bypass and trails, so effects such as reverb and delay can continue to decay naturally after a footswitch is turned off rather than cutting off abruptly.
How much does the MAW cost?
The MAW is listed at $299.00 USD on the Old Blood Noise Endeavors product page, as of 25 October 2026.
Can I use an expression pedal with the MAW?
Yes. The MAW has expression jacks that let you externally manipulate one knob each of both the A and B effects banks, so a pair of expression pedals can control one parameter in each bank at the same time.
