So I was playing the old bass yesterday after having just plugged into my cab, and there was a sort of sizzle and then a bit of a pop and then nothing. I went through the usual diagnostics, and I've determined it's the 1/4" jack on the speaker cabinet that is the problem. Two questions: 1) What are the chances of the second jack crapping out on me now too? I have a rather important gig on Saturday that would be most inconvenient to have my cab stop working during... of course I'd still have my 1x15 on the bottom but the 4x10 is the one that will be mic'd. 2) Is this a difficult fix? Think I could do it myself? What's involved? Also, the horn on this cab hasn't worked since I bought it used a couple years ago. I assume it's just the case of one of those bulbs being burnt out, so I figure if I'm going to be in there I might as well take a shot at fixing that up too. Anyone know what's involved here? Anyone have experience working on one of these cabs?
