Hey Mica, as you say so many different possibilities. The lead I made also works as a mono lead so a bit of versatility there. I spliced a tail onto the 2 core cable to get the 2 channels, and if I just use the tip jack and switch to mono it works as normal (whatever normal is LoL). I might put a TRS jack on the amp end and make up a TRS socket to double TS so I don't have the extra TS tail hanging (it's about 5" long). Then easy to use either way. This is a feature I'll grow into over time I suspect as I continue to explore all the amazing sounds this bass makes (lets my fingers make). I haven't tried it direct yet as in either just into the desk or I'll probably run it through my Ivory 5001 tube (hybrid really) preamp into the desk and insert the Focusright (platinum Penta) stereo compressor.
As an aside, I got a longer 3.5" strap the other day, going lower has helped both with the neck balance (as does the wide (very supple, suede underside an NO padding (tried one with foam padding inside, it went back) strap). My right hand is also more comfortable, slapping is easier and it's a more natural position for me (after 40+ years on guitar).
