If you can trace where those components connect to and can solder to a non-burned area that might work better than trying to reuse this location. I don't like how narrow Tech 21 goes with their PCB routes, they are fragile. It's not like they are saving money on copper or anything. Dealing with Tech21 for repair support is interesting. I talked with the engineer for like an hour when I was fixing a Trademark 60 last year (about the amp and then just shooting the breeze). If he could have send me a schematic, or even a screen shot of the section of the schematic or board layout it would have been much easier, but I got the fix done and everyone was happy.
