hey guys... ive just had a thought... ive been looking at a new DI box recently... just a cheap one to tide me over for a while and have read that most can cope with speaker levels signals...
does this mean that i can put this between the head and the cab of any of my old valve heads?... using the input jack from the head and the link jack to the cab... would this cause any impedance problems? would this cook the DI box?

i thought this may sound either quite cool... or absolutely dreadful?

i dont want to damage any of my heads (marshalls, carlsbros, voxs, wems etc...)

thanx for any help...
