fender faceplate searching!
Hi, I'm looking for faceplate and rearplate of Fender blackface or silverface era, Bassman or bandmaster.
There is someone who reproduces these plates, or if they can be purchased on some site.
Thanks in advance
Sergio

Re: Steel String Singer #002 Build - Noise Problem
Hi , congrat for the build.
If you have a good twist AC rail , I suggest to check all the PCB board solder ground joint. And re-adjust your lead dress
Sincerely. I don't like the pcb for this type of amp, but that's my personal taste.
