I currently have a Vox Vt120+ that has an auxiliary cord for an output. I recently acquired an 8 ohm combo amp that i'd like to be able to use. My current setup to do so is currently a little bit of an eye sore, Vox->Old fender amp->Cab. What i'd really like to do is find a way to run my Vox combo amp to my cab, I know that in order to do so it would have to be a powered output, but upon looking online I can find no information on how to do so. Any help is appreciated.
So if I understand you correctly you just want to run your vox vt120+ through an external cab? If that is the case you just have to add a speaker out, and we have a nice tutorial for this:
