Could only squeeze in 10 minutes to test it this afternoon, but the verdict is a thumbs up! The 'bottom end' mode is very bassy, but sounds much better played with a pick, somehow the sharper attack triggers the sound better and make the organ sound much fuller.
There are a few mild tracking issues, I only tested with a 4-string passive P and for some reason a low A generated a slight warbling sound in the low end yet the top end of the organ was still nice and clean. It's as if there is a POG-like digital octave up which is stable but with a tiny bit of latency, mixed with a less stable but instant traditional octave down going on. Low E to G were perfectly fine though. I have a feeling a brighter bass with more attack like a stingray would suit this pedal more, that'll be the next test, as well as the 5-string BB.
Playing dry droning root notes, then kicking on the pedal and chucking in some upper chord notes was a lot fun!
Favorite modes were the first, 'fat and full', and the last, 'bell organ', which was a surprise as that was the model I liked least on the demo video.
And before anyone asks, sorry, too busy to sit down and explore it more today and tomorrow, let alone record clips! I'm free Thursday evening though so maybe then!
