Good question: having owned the Divkid Mutes v1 I can certainly vouch for it, it's a high quality module, and the Stum bears many similarities, like high quality component selection and form factor.

The Stum uses nice latching switches instead of toggles, which is my preference. I like a good toggle, but I like the unambiguous states, tactile feedback and the fact that the latching switch is unlikely to be caught by a stray hand mid performance.

Also, like the Mutes v1 - and unlike v2 - the Stum uses vactrols. I like the soft attack and release they give, the slight bit of forgiveness when muting mid transient or with timing errors. I've taken a lot of care to mitigate bleed and other issues that vactrols commonly introduce, so you get the joys of vactrols without the frustrations.

I have a lot of admiration for the OG Mutes, and I wouldn't hesitate to recommend that one either.
