amp question on a fender princeton 65?

i got a princeton 65 and im usin a bc rich worlock. It seems everytime i use the overdrive channel i get a buzzing sounds kinda like the springs are buzzing? ne one have ne ideas? please help. and if u got one what are some good settings. right now im using basic 5's across the board. drive is at 5-7, but volume is low. if u have one pleas epost ur settings. lata and rock on

I have a Fender Deluxe 90DSP, kinda like the Princeton. I don't know what the sound is, but if I'm playing like, in my room, I have the volume on 1.5, treble at 7, mids at 4.5, bass at like, 6.75. I don't use the amp's overdrive.

thankx man, but the 90 watt has more options int he clean mode then the 65, which only has bass and treble. I shoulda went wit the 90 but when i bought it i was just wanting some more wattage to play wit drums and bass. i should have looked around more huh? But i like the amp alot. thankx for the advise
