So I have a Sunn Beta Lead combo amp and just today when I decided to turn it on, it produced a massive hum/buzz thing and I had to turn it off. I tried it another time and it did the same thing. Guitar was indeed plugged in, in case anyone asks.

I'm not sure what's going on. Am I going to have to take it to get fixed? Anyone know what the problem is?

Try different cable/guitar/amp combinations. I had a similar noise and is was just my cable crapping out.
Gibson RD Silverburst w/ Lace Dissonant Aggressors (SOLD)
Electra Omega Prime Ceruse
Fender Franken-Jag Bass

Amps and the like:
Laney VH100R
Seismic Luke 2x12
Dunlop 105Q Wah
Gojira FX 808
Line 6 M9

Unplug the cable, still nasty buzz? If so she probably needs to visit an amp Doc.
