i'm mostly going to use this head for recording since i have an ampeg b2r head and svt410hlf cab. the 1x15 speaker and enclosure that was part of the ba-115 i want to make into an optional cab for the main rig and use the head for recording. this means i want to put a 1/4" input on the cab and a 1/4" output on the head. i already took them apart with ease. they're connected with this thing..... any ideas on how to do it?
