Yes that's the one. I think that's probably where I first saw it, too. After buying one cheap and selling it in favour of the 'better' flat green model, I bought a sparkly one again, then sold it for a super early one, then sold that one... I just didn't think the earlier ones had the same 'wetness' to them.
I dearly love my 3Leaf Wonderlove because of the way it 'wobbles', my Funk-U-Lator because of the synth octave part which goes into the filter and I quite enjoy a Bassballs, too - but the FX25 has that 'growl' on the bass notes which nothing else seems to be able to replicate.
I experienced volume drop with some of the ones I've had but this one seems fine - I run it into a limiter to tame the big bass spike as the filter closes but if anything I'm pretty sure it's overall louder then the clean signal.
I'll try and do a video now that I've sort of worked out how to do a decent one!
