In an attempt to I believe conserve some money. I was thinking about possibly running a power amp through my workingmans 40004 head. I like the tone it gives me. Nothing great, but it does well enough. The thing is, can that be done? I was thinking of running an Crown PA throught it(Im not sure the model but something of around 1200 watts) through the head and my avatar B410 Pro. Would this be a good setup/work? Or am I better off saving up for a cheap pre-amp(Sansamp RBI) and selling the workingmans head alotgether.
