The Electrix Mo-FX is a full-rack, time-synchronized multi-effects unit that puts distortion, flange, tremolo/pan and delay into four independently engaged blocks1. Each block can be switched in or out on its own, so the unit works as a single combined processor or as any one of its effects alone. Because the blocks are time-synchronized, the modulation and delay effects run against a shared clock, which is the design idea behind the unit.

The four effect blocks

The Mo-FX carries four effect blocks: distortion, flange, tremolo/pan and delay1. The distortion block covers the drive side of the unit, a subject Tonebox treats in depth on its Distortion Pedals page. The flange block handles flanging, while the tremolo/pan block covers tremolo with the added ability to move the signal across the stereo field. The delay block reaches a maximum of 2.6 seconds1, which places it in the same territory as dedicated delay units for anything short of long ambient loops.

Because the blocks engage independently, a player can treat the Mo-FX as four effects in one rack space rather than a fixed preset chain. Electrix lists the unit as a multi-effects processor, the rack-mounted counterpart to the multi-effects pedals most players know from the floor1.

Connections and MIDI control

The Mo-FX is a stereo line-level unit. Its line connections are stereo balanced ¼-inch and RCA inputs and outputs, and the effects insert is stereo as well1. That makes it at home in a mixer's insert points or a rack setup rather than in a guitar amp's front end, which expects instrument level.

For control, the unit offers MIDI in, out and thru plus footswitch control1. MIDI in and out let it sync and be programmed from other gear, MIDI thru passes data along a chain, and a footswitch gives hands-free block engagement on stage.

A legacy, driver-free unit

Electrix now lists the Mo-FX among its legacy products1. The maker describes it as standalone hardware, "so there are no drivers, software downloads or product-specific FAQ entries to hunt down"1. For a player picking one up secondhand, that means the unit runs on its own once wired into a line-level setup, with no computer step involved.

Questions

What effects does the Electrix Mo-FX have?

The Mo-FX carries four effect blocks: distortion, flange, tremolo/pan and delay. Each block can be engaged independently, so you can run one effect on its own or combine all four at once. Because the unit is time-synchronized, the modulation and delay effects stay locked to a shared clock rather than running free of each other.

How long a delay can the Electrix Mo-FX do?

The maximum delay time is 2.6 seconds, according to Electrix's product page for the unit. That covers everything from short slapback and doubling effects up to longer, more spacious repeats, all within the unit's time-synchronized design.

Does the Electrix Mo-FX have MIDI?

Yes. The Mo-FX has MIDI in, out and thru, plus footswitch control. MIDI thru passes incoming MIDI data on to other gear, and the footswitch input lets you engage blocks hands-free from the floor.

Is the Electrix Mo-FX stereo?

Yes. The line connections are stereo balanced quarter-inch and RCA inputs and outputs, and the effects insert is stereo as well. That makes it usable as a stereo line-level processor in a rack or mixing setup.

Does the Electrix Mo-FX need software or drivers?

No. Electrix describes the Mo-FX as standalone hardware, so there are no drivers, software downloads or product-specific FAQ entries to hunt down. It operates on its own once connected to your line-level gear.
