Here is the story I have
heard from a few guys in NH who were familiar with Bedrock operation. Before the company was known as Bedrock, the first name
for the amps was "Fred". I have no idea how many were made, if any, bearing the "Fred" name. If there are some floating around
out there, they have to be pretty rare!
If anyone has more info about the early Fred amp days, please let me know!
