So I just noticed yesterday that my 1048h has a buzz when I play the seventh fret on the f string (c standard tuning). It gets louder as I raise the volume and isn't present at the lowest volume. I've taken off everything that I can possibly take off and felt around while buzzing and I can't find the issue. I'm playing through a v-type 300h head if it helps. At this point I'm thinking it's the horn. The sound is coming from the front of the cab. The horn attenuator has no stopping point, it just spins freely so I don't think I'm having effect on it. There's resistance but doesn't stop. I don't use the horn and at this point I'm thinking of cutting the wire. I just can't take this buzz. Help
If you do snip your horn be sure to refer to your cab as a 1048 from there on in.
My 1048h rattles but that's because my amp is loud. Both port covers have been smashed off and I think it's making the grill rattle. Either that or one of my speakers has finally crapped out on me. Anyway, who cares. My favourite thing about my 1048h is that I can frequently ride it around the stage and jump off it and use an amp that nearly doubles it wattage rating and it doesn't even break a sweat. I think the cab will probably outlive me.
