    Any reasons why I should not use this for a guitar amp build?

    I think its fine. Lots of builders over at the Amp Garage use them...

    ... but if you want a ultra-fast diode, I would recommend using a UF4007. I use them with great results. I belive they are actually faster recovery next to "freds" and they are the same size/shape as normal IN4007 diodes. I've found they actually do improve the sound of an amp (especially when pushed hard)

    Better hava long talk with Kevin Oconnor about that one.How exactly can a fast recovery diode have an effect on the sound of a aguitar amp that does not have the frequency range to appreciate it i can't really say.

    The 600V rating could be a problem, if the transformer has a higher output than say 400Vac. 425 Vac has a peak voltage of 601V. A 1000V rating would probably be better.

    My tranny will be 300-0-300. So I guess I'm ok? Each side will see 300vac?
