Kinda a noob question. So i just got a Randall rh150 g3 head and it has a line out port on the back panel. does this allow me to record directly to an audio interface with it by using a cable to connect the head from to line out to the audio interface or is the line out used for something else. I dont have a cab yet but i want to try the head out and see if everything seems to work and sound good (i got it off ebay)
Pretty much, but it shan't sound as good as it would running through proper speakers.
Make sure you have a cab plugged in whenever the amp is on, to avoid damaging the amp.
