All user reviews for the MXR M180 Omni Multi-Effects Unit

This rack 2 units (88 mm high) fully analog incorporates several effects: a compressor optical detection style MXR DynaComp, distortion style MXR Distortion +, an equalizer with three frequencies assignable before or after the distortion, an analog delay style MXR Analog Delay (running from circuit BBD rare Reticon SAD 4096), and a chorus / flanger style MXR Stereo Chorus with potentiometer feedback. The difference between chorus and flanger is a change in frequency range of vintage clocks circuit Reticon SAD1024. Everything works on the area!

External effects loop is assignable where desired: after compressor after distortion or post EQ after the deadline. A foot control, equipped with LEDs booster works via a multiplexer, so it communicates with the rack with a cable Jack mono 6.35.

The vintage rating this product when it is in perfect working order is 800 euros, no offense to those who are thought to have bought too expensive at 220 euros! The seller is separated completely unaware of because, apparently, or he sold it because he was in a hurry!

I remember that it is all vintage effects with a known reference in the catalog MXR, and the price is related to vintage.

There is only one MXR OMNI 180 in the world with a doubling of the base of the foot control Jack (one right, one left), the insertion of a combined outlet IEC + filter mains fuse accessible from the outside, the doubling of the connectivity front / rear with a split stereo jack into two mono jacks, associated with screen printing. This is the MXR OMNI180 Dr Boost, completely restored, almost like new!

UTILIZATION

Switching between the different effects of the respective bypass occurs in silence. The foot controls for each effect (the five above + outer loop) takes the form of a push button recalled by a red LED, while the bypass generally works through continuous contact (illuminating a green LED).
The configuration of each effect occurs very intuitive, due to the simplicity of the settings and their effectiveness / musicality respectively.

SOUND QUALITY

The sound is huge, it's vintage distortion is fat and the compressor has a ballistic own optical detection systems, smooth, providing sustain. The three-band equalizer is very effective. Time delivers great sound, like chorus / flanger, fat. The MXR Omni 180 also works well with guitars that passive active models (incorporating a preamplifier).

OVERALL OPINION

I use this rack for a long time. It was the first rack MXR tried, and I did well to trust the quality and reliability and this legendary brand.

The sound is absolutely fantastic! For a vintage product, its rating of 800 euros is not misused: Calculate buying pedals VINTAGE corresponding to separate elements, add AC power to those who are deprived, add routing (assignments), and the now untraceable delay lines and Reticon SAD1024 SAD4096 (appeared on the market before the Panasonic MN3005 / 3007/3205 etc..

The value-reliability-sound is excellent.
If necessary, I would buy one willingly.

Multi-Rack EFET, seeming to date from the 80 or 70.
Each part of the multi-effect is via a bypassing pdalier (connected by a jack to bte Rack).
You can also bypass the entire rack from pdalier.
Dtail trs cool: you can have an effect loop from the rack and operate from pdalier ...

While analog. UPR is a "Best Of" MXR pedals of the era.

Obviously not ditable via PC or MIDI

Diponibles effects are: Compression, Distortion, EQ, time limit, Chorus / Flanger, outer loop. You can change the order of most of these effects.

There is one input and two outputs (for 2 amps it seems).

UTILIZATION

If the rack door arm is really gnial: it operates at the foot, is corrected as and when the hand without lowering the top.

I do not have the manual and frankly I do not see how it could help me so much is clear ...

SOUND QUALITY

The effects are effective, Yes!
If you know a little MXR effects, I do not need to go write ...
Otherwise know that it is both warm and round-edged when necessary (distortion / compression trs effective).

Caution, do any of the same prvoir a little "crunch" or distortion supplmentaire in the loop of your amp or rack: one type sound "distortion" on the rack will be short if you want to change sound during a song ...

My Rack starts to need a cleaning, and virtually no effect does not work, it's more a amricaine version and I use a small transformer 220/110V quite noisy ...
So I think again make cablges and change certain components of the rack by a Pro ...

OVERALL OPINION

I use it basically for a year.
What I like most is the sound, the number of effects and their respective qualities, the pdalier and comes with jack.
What I like least on mine, is the fact that either 110V for now ...

I had a lot in the hands of pdaliers (Korg Pandora and other Line 6 Pod Boss GT6) and none had as many "prsence" or cutting edge that MXR. Warning, this is not a factory-type gas "GT6"! 5 or 6 and it effects everything, but as long as they sound ...

I pay quite expensive (in 220 Euros) and it did not work well trs beginners.

Yeah, I attempt the journey again if c'tait

Nothing to add from the previous comment, if not a touch tone system to place the distortion before or after the equalizer, and place the loop where you want to insert between the effects (after the compressor, after distortion after EQ ...)

All analog MXR with sound on all floors

UTILIZATION

Nothing could be simpler
The pedal (required to run the beast) can trigger each effect, each effect has settings simple and effective on the rack
no manual, but what could it serve?

SOUND QUALITY

While there, we wonder where is the progress on the effects since the 80 ...

The sound is amazing, hot, with settings simple and effective

I particularly recommend compression, EQ and ... DELAY, which although a little short, this is natural and

Breath is quite acceptable for an analog machine, even when all effects are switched

OVERALL OPINION

I use it for 2 years and I can no longer listen to digital multi effects without a little grin! good blades copies of "real" effects like the MXR

bought used 265 euros, I would do without hesitation that choice

Only caveat: electronics lived (given its age, it is normal), and I will soon restore some order within (a knob death and bad contacts in the food)
