Had an MBase01, later an XBase 888, both produced monstrous kick drums. Both can create a huge variety of sounds. Boomy or punchy, subby or mid-range, 808-ish or 909-ish. Especially on the XBase you can make the kicks sound distorted by switching waveforms. You see, a lot of potential.
BUT, bot sound super raw and they take up quite some frequency-real-estate. At least an eq to tame the midrange and make room was always needed.
Unless, your sound is mostly kickdrums 
What I ended up doing was processing while recording samples. I had the XBase on a mixer, kickdrum to one mono Chanel, stereo sum for the remaining drums. And deliberate use of Amp saturation to even out dynamics and eq to make room for other instruments.
All samples recorded from both boxes where processed in a similar way.
Jomox sounds brutal, I always wanted to take the XBase out on a huge PA to scare people.
Ended up selling both, the mbase because I was a poor student and the XBase because I was only using it for kickdrums which is a waste.
The OT is still very happy with the samples I recorded, but I also got an TR8s which sounds cleaner (can sound drity, though 
) and more ready to use. If you look at the frequency response on say kicks and Tom’s you can see they already have space for other instruments.
To your topic question: Jomox is worth any cent spent on sound-wise, but as with most analog gear, needs some love to tame the wildness.
For a live-rig without any processing I see other instruments being buried next to Jomox stuff
At least that’s what I figured.
