I have a Nashville 400 amp. When I turn the reverb to around 5 it starts to making a roaring sound. Any Idea?

There is likely some corrosion in the reverb connector that plugs into the bottom side of th eamp circuit board. You can see it if you look into the rear of the amp and above the speaker, near the bottom center of the amp circuit board. You can see this without removing anything, or possibly removing the upper back panel. You might do a search on here for "reverb molex" and should get several hits on it. There are likely more than one from Ken Fox explaining it a bit. You basically need to clean the connectors a bit, and tighten then a little, and it doesn't hurt to add a little di-electric grease to help avoid future corrosion. That has solve a load of problems similar to your symptoms. However after doing that it is still possible there is something else wrong, but I would do that first to eliminate it as a possibility. Plus it is not difficult to do.
Good luck!

| Everything Chuck said! Also pull the pan and make sure that the internal piece that is suspended by 4 springs had not gotten jammed and is not floating freely |
