Can I use my Fender Deluxe Reverb Reissue as a speaker cab until I acquire a new speaker cab? I am putting together a new rack rig (SMS) and would like to use the JBL K-120 in the combo as my speaker short term. Would that work and would I just solder new wire to the speaker and install a 1/4" jack somewhere on the back of the DRRI I am a totally novice wiring person! If that can be done, what kind of wire would I use and how would I also hook it up to the 1/4 jack? Would be appreciative of any advice. Thanks!
