You can still use a cab, but with the Torpedo Live, it's either all attenuated (a load), or 100% signal thru. I gig (well, I did, before the pandemic), so I still use cabinets in my garage to dial-in tones. A couple of the Two Notes products have attenuators on them... I think their newest line have them, so you can dial back your cabinet. But honestly, if you have really nice monitors or headphones, once you go Two Notes, you really don't need one, if you're only making music by yourself.
