what's the deal?? just received a hiwatt tape echo from the emporium today. Plugged it in and I'm getting no wet signal. As far as I can tell all the controls work. Volume turns up the gain, time changes the tape speed.... I'm just getting no echoes. Anybody want to help me out? I'm hoping I was just hooking it up wrong, but I messed around with it and the manual for like an hour and couldn't get it to rock. any hiwatt echo owners or tape echo connosseiurs about??
