I can get a lot of the same sounds with the small one. The Mid knob is the same control as the 500Hz slider on the big one.
To people that say this sounds just like the B7K: it totally can if you set it that way, but moving the HPF control and hearing the different sounds you get just by doing that is quite amazing.
The main difference between the X the other Microtubes is that you have much better control over the distortion characteristics and its clean counterpart.
It cab also retain the attack, presence and clean low end with older strings or thinner basses remarkably better, and the ability to add “size” with the filtered cleans (compressor or not) is really cool.
I never claimed to have designed something radically different than the other Microtubes (I did add the “Microtubes” part next to the X), but it’s far more flexible and fully adjustable.
The palette of available tones is vastly more diverse due to the parallel filtering setup (audio engineers and producers have been doing this for decades, and for a good reason).
Hopefully once the first people here start getting theirs they’ll be able to chime in, talk is cheap

Kind regards,
