Yes it strange, because it's one of the most popular one in the bassists club.
By the way, as I have now the VT and the American plugged on my pedal board, I used them to have 2 separate tones : one for pick playing (the American) and the VT for finger playing. Easy to set both of them, and easy to switch from one to the other.
And so I was figuring that, for a lower cost than the VT Bass Deluxe I could buy 6 Joyo preamps and have the same amount of possible settings but with different flavours due to the models I could choose !! I will not do that, but thinking of it is fun
