Step 2If it's too loud, you're too....
The output side of this thing is a cheap megaphone from Harbor Freight. Watch their sales, I see it come up every couple months for about $5 US (Normally in the $15-$30 range). The things I really like about this unit are a) the handle comes off easily, and b) the amp board both easy to get at and is completely self-contained. There's no remote switch in the handle like some other designs.
For a modification, I simply de-soldered the on-board microphone (you could reuse it in the design, if you want!) and soldered in a short piece of 24gauge CAT-5 wire. I soldered that to the RCA plug, enlarged the mic hole a bit with a utility knife (note, safety first!), and hot-glued it in place. Again, I'd use a smaller connector format next time.
Also, I'd secure it with cyanoacrylate (thin super-glue - check your hobby store and be sure to get Thin) and baking soda. It's amazingly strong - like concrete. To use it, put down a thin bead of glue, sprinkle in baking soda. When it's dry, repeat. Add a couple layers and it'll never come apart.
