Fender Frontman 25R amp settings?

[lefty01]

Hi.
I have a Fender Frontman 25R. I need help in getting a classic (80's) metal sound from it. I know this isn't the best amp for this, but it is all I have to work with for now.:o

I've also got the same amp and am also interested in knowing good settings for it since I always seem to mess them up.
