He even spoke up a few months back on a similar "I'm looking for a subtle OD" thread and said that anyone who thinks DG gear sounds anything like a tube amp has never played through a tube amp before, and that it irritates him that they even use the word "tube" on their products.
I mean... that's totally true. They definitely don't sound or respond anything at all like a tube bass amp. I guess it doesn't really matter. There are tons of accurate youtube demos of the DG pedals, pretty easy to tell if it is something you'll like.
