@khz,
The entire Duo X saga didn’t play out well for Mod. Their initial version (LE) is different that the production version, and it has some limitations that angered users in the past. MOD decided to offer a trade-in option for LE users to upgrade to the production model. See more here.
Unfortunately, timing was not on their side. In 2020 some parts just disappeared from the market or had their prices go up a criminal 1000% (like the NXP chips). So MOD was badly constrained as to how many units they could sell. The X was supposed to be a major source of revenue for that year, as @gianfranco explained in the insolvency message. Part of the cash crunch of Mod Devices began right there in his words.
Months later, they were attempting to replace some components with others more readily available and/or more decently priced. Either due to time or money constraints, that didn’t produce tangible results (again, per their words).
My feeling is that, had they been able to re-develop the Duo X so as to make it ready for production, at some point in the near future, they could restart manufacturing those – give or take the fact that its production is not as streamlined as the Dwarf. Plus, they have a stance whereby the business case for the Dwarf as a multi-effect might be preferable, in spite of many people who are guitar/bass players prefering the X to the Dwarf (I am one of them.)
HOWEVER
This is just speculation at this point.
The supposed higher profit margin of the X may not be as tempting if the production is more complicated and there are more risks associated with it. There is the (sad) possibility that a relaunch without significant changes – such as from LE to production – won’t be possible. It might be complicated to source parts and that might also hamper Dwarf production to some extent. These are all real possibilities that we might have to face.
Again, without a formal word from Mod Audio, we’re just guessing. Sadly, their unwillingness to even touch this topic is beginning to scream in our ears.
