I connect my 6505+ head to my hotplate input with a speaker cable.. Does the speaker output need to connect to my cab with a 2nd speaker cable? or will an instrument cable work
4 views really? cmon
speaker cables ONLY. amp goes into input jack and line out goes to the cab
If you are heavily attenuating the amp an instrument cable from hotplate to speaker could work, but I strongly advise against it. Speaker cables are cheap man.
