How to Use Mobius Pre/Post Mode

How to set up Mobius Pre/Post

If you own Mobius, you’ve seen the Stereo In/Out – Pre/Post switch on the rear of the unit, and the PRE/POST setting in the preset menu.  Do you know exactly what this Pre/Post feature is for, and how to use it? If you are a little fuzzy on the details, read on, and then check out the video below!

The position of a modulation effect in a signal chain can drastically change the sound that comes out of the amp. If you have ever tried a wah pedal, a chorus, or a flanger in front of a fuzzed-out distortion pedal and then tried moving the same effect after the distortion pedal, you know that there is a big difference in the resulting sound. The internally selectable PRE/POST setting on Mobius allows you to experiment with the position of Mobius in the signal chain without repatching cables or reordering effects in your pedalboard, and this setting can be saved on a per-patch basis.

Here’s how to do it:

  1. Hi, I just bought a Gigrig 2 pedal board, partly because it works with midi and means you can, in theory, recall a patch on any midi pedal. I found out from Gigrig that Strymon pedals cannot receive patch changing data from other pedals, which means that you have to take the midi patch per pedal that is automatically assigned to i.e the timeline or bigsky and change those patches. Personally, I don’t believe The Gigrig (Daniel Steinhardt/ Joe) I believe that it is their pedal board that is at fault. I thought you ought to know this as they are actively saying that Strymon is at fault and the midi functionality to change patches to any patch, as long as you assign it, is not available in Strymon pedals.

  2. Hi Lee. Strymon pedals do receive program patch change information, but you can’t map the presets. What you can do is copy and paste the presets. I’ve posted a video on our Facebook page, contact me directly if you need any more info. Cheers Lee

  3. Where exactly in my signal chain to physically put mobius in my signal chain.
    Shure glxd 16/buffer/volume pedal/compressor/noise gate/tube screamer/distortion/big muff fuzz/ep booster/strymon dig/fender tre verb/Iridium

    1. Most people will put modulation between drives and other time based delays, so you can put it after that EP Booster 🙂

  4. Hello. Great video. Is it possible to use the pre-post function after a chain of pedals, as opposed to after just one pedal as shown on the first video? In other words. is it possible to connect the Mobius output to an overdrive (let’s call it OD1) which is connected to a second overdrive (OD2), which is connected to a distortion (D1), and then connect the output of D1 back to the Mobius in order to have this two possibilities?

    Mobius -> OD1 -> OD2 -> D1

    And

    OD1 -> OD2 -> D1 -> Mobius

    Thanks!

    1. Hey there! That should work just fine, you can put multiple pedals within the PRE/POST loop, and it should work just like that.

  5. Hi, i’ve had my Mobius for years and it’s beaten off all contenders and continues to do so. I have it set for pre/post, running it through the fx loop of my amp. Here is my question – I now want to use an Iridium or Walrus ACS1 for a direct amp-in-a-box solution. Neither of those have an fx loop, so if I have the ACS1 in the middle of the chain rather than at the end (like a real amp), is there a way to still route the Mobius in pre/post?
    Thanks, open to any and all sugestions.
