I don't really know my way around the guts of an amp very well, so I have kind of a novice question - As is popular with many who own the Fender Excelsior, I was planning on swapping out the speaker and trying some different ones. But when I went to unscrew the stock speaker I discovered I can't get to one of the screws. The very bottom screw to the baffle is tucked behind the power amp enclosure and I can't seam to get a screwdriver in there. I've never run into this before when taking out a speaker so I don't know how to get around it. I know it can't be that tough because I've read about thousands of others who have replaced the speaker in this amp. I tried to unscrew the power amp enclosure and temporarily move it, but even after removing all visible screws it still seems attached to the cab somehow. Like I said I don't really know what I'm doing, so I don't want to go any further for fear of messing something up or not being able to get it back together properly. If there are any videos out there I could be directed to or any advice/ instructions that could be supplied it'd be much appreciated. Thanks everyone!
