So I have a friend of mine left his Vox NT cab loaded with the greenback at my house. I decided to run my AC4 through it and compare the sound to my AC15C1 and was I surprised by how close they actually sound. The AC15 is louder and has much more tonal tweaking ability with the two channels and the much improved tone control range. But in a pinch, I think the AC4 through the same speaker will get you very close. Gives me high hopes for the AC4HW coming soon. Maybe I should return my AC15 (still under 30 days from GC) and flip the AC4TV to get the funds for that one?
