I was in this part of town and starving, but wasn't feeling a chain sandwich place for whatever…read morereason. I was pleasantly surprised to find Jambox very close. I found a very simple website with menus, but not the ability to order ahead of time.
I got the vibe that it's a brand new business just getting up and figuring itself out, so I'm more willing than usual to give it the benefit of the doubt and some time. They have a cassette tape theme going on, so I guess the owner has a thing for older music and the culture of cassettes, which aligns with the "mix tape" loyalty club. I suppose that also has to do with the name.
All the sandwiches have "fun," but non-helpful names, so I had to read all the descriptions a few times to get an idea of what they had. He pointed me to the option that was most like an Italian sub that I was craving. It wasn't clear, so I had to ask about where I tell them how I would like it (no tomatoes or mayo, etc) and the answer was right there at the register. I didn't see general options anywhere, so I didn't know how else I might customize, plus I was in a hurry and not in the mood to have that conversation right then, or in person, for that matter. I paid (kudos for having contactless payment options!) and went to the other end of the counter for a brief wait, then I got my sandwich and was out the door (my order was 'to go.')
The sandwich was good, I ate it all and enjoyed it. The nature of its construction made it less stable and more fall-aparty than I was expecting to eat while driving (part of the reason to get a sub), but I made do. The bread was a little disappointing. It was good, but I think my expectations weren't aligned. I wasn't offered a choice of bread and I don't remember if there was an obvious "choose your bread" display right by the register or not. It was white sub bread. The outside of the bread was just as white as the inside; I guess I'm used to the outside of the bread being a little darker than the inside and a bit stronger to hold everything together. It was a bit more crumbly than I was expecting or thought was appropriate for a sandwich. This also meant it was more flexible, as in while I'd hold it to take a bite, the back of the bread would lift up and let things fall out that I had to put back, and then adapt how I was holding it to keep all the good stuff inside. I don't remember the bread having any flavor, it was just an edible tool to hold the sandwich innards. Normally I'd add oil/vinegar to an Italian sub, but I'm glad I didn't here or it would have been a bigger oily mess to clean up rather than just putting it back when things fell out.
Bottom line for me (if you had a different experience or have a different opinion, I'm happy for you), it was good but not amazing. I don't think I'd stop there again when I'm in the area unless I'm starving again. If it were closer to me, I might keep my eye on it to see how it matured and adapted over time to maybe have options I liked more, but I won't be making the trek to where it is in Franklin just to get a sandwich there.
However, since my taste isn't universal, if you're in the area and curious, I'd say give it try. You may really like it and the cassette thing may speak to you. I wish the owner only the best!
Tangentially, nothing to do with the food or business: It's on a busy road and the entrances there are a little tricky, so just be aware and don't pull in slightly too soon and find yourself in the wrong parking lot that isn't connected.
