Circuit designs are actually not protected by copyright, unless you design something that is considered new technology and you patent it. Most of the circuitry in Marshalls is based on designs and technology that date back to before 1950, so it can not be patented because it's pretty much considered "common knowledge" for electrical engineers.

A circuit is just like a recipe for baking a cake. But have you ever had the same kind of cake, baked by two different individuals? they taste different because everyone uses their own methods of making it, even if the recipe is the same.

Also, building an amplifier is not something everyone can do, it takes time and skill, and sometimes a company like Marshall can just do a better job for less money than you ever could. (getting back to the cake analogy, why do we have bakeries if we can all bake our own cakes?? Well, because they make some fine cake, and maybe we just want a damn cake without the hassle of making it )

teemuk, you rock!

Hi there. I've been looking everywhere for the schematics for Sunn Beta Lead, can't seem to find them anywhere online. I know its possible to buy them from Fender but I live a long way from America and it would really be a hassle to get them in the mail.

Just wanted to give it a shot, and see if anyone had the schems in digital form...?

Thanks in advance.
