When I buy a bass, the first criterion is sound, then playability, then looks.
I used to play in a coverband with a set ranging from the old James Brown stuff, to Avicii, to Rage against the machine. As I don't like switching basses on stage, I always took [url="https://ritter-instruments.com/item_info.php?i=415"]my Cora[/url]. And this one doesn't even have the most flexible electronics (active only [url="https://ritter-instruments.com/electronics-files/RITTER-C3-Electronics_Active.pdf"]C-3 electronics[/url] => mid tone cut/boost at a specific low-mid frequency).
When my students ask about the sound of Ritter basses, I let them hear 6 recordings and ask them how many different basses they think they hear. Most say 4 or 5. They're quite surprised when I tell them all grooves were recorded with the same Ritter bass.
For my first R8 I asked Jens for a specific sound (I gave him some recordings of bass sounds I liked) and I got a bass what almost exactly that sound.
As Molan mentioned, Ritter basses do have some serious sub bass.
The most flexible option would be active/passive Master electronics with triplebuckers.
