Sorry to hear about your accident. And I hear you about lugging around a double bass.
No, a guitar style bass definitely does not have the same visual, and to me at least, that visual is pretty important in some instances. That's why I bought a Barker electric upright pictured above. It looks pretty cool and transports better than an acoustic upright... but it sounds more like a fretless Jazz bass than an upright.
If you are looking for an upright sound in a bass guitar, my AC6 classic can definitely sound like an upright, but the EQ and amplification are important components to making that happen. I use the bass's preamp to boost the bass a touch, and then the preamp on my rig to dial in more mid and lower mid, and a crispness with highs.
I have a friend, a jazz pianist, who dislikes EVERY digital piano. She says none of them sound like an acoustic to her. I remind her that she is comparing an acoustic piano's acoustics in a room to a digital piano's sound through an amp. If you mic an acoustic and send it through an amp, it will sound just like the higher quality digital pianos.
I think the same holds true for the AC6 Classic. Playing an AC6 classic through an amp sound pretty close to an upright in a room, but it sounds exactly like a mic'd upright playing through an amp or PA.
My AC6 classic does not have a magnetic pickup so it can be as dedicated to sounding as upright as I can make it.
George prefers the nylon coated strings, and I definitely like them too, but I prefer Thomastik Infeld Jazz flats. These nickle strings sound more like most uprights to me, they are extremely soft though, which I guess some players dislike but I sure don't.
So I dedicated my AC6 classic to approximating an upright, and my AC6 Signature with a magnetic pickup is dedicated to having an excellent electric bass tone. I have DR Drop Down Tuning round wound strings on her.
I adore its milky, fretless tone -- Jaco like but a bit thicker. I also like blending in the piezo to give it its own voice. With TIJFs, however, it approximates an upright fairly well, particularly in a mix.
You might want to do the same: keep your BNF focused on excellent electric bass tone, and then get an AC with a focus on upright if that's what you are wanting.
