Ok. Let me just say right off the bat that I am a real moron when it comes to anything like this. I mean, I've had a few successes here and there but I'm just not mechanically inclined. I pretty much let the pros do everything for me from guitar related repairs to working on my car. But this one seems too easy for me to take to a tech and I really want to be able to maintain my own stuff. I need to get to the fuses in my amp. Do I just take the four screws out of the top of the amp that hold the chassis in place? Is there more to it than that? Will the whole assembly then come out? This is where I need to be Thanks in advance.
