Hey, that looks familiar.
Some good advice so far. My personal tastes run to using either C90s, CL-80s, or G12K-100s (since you can't get the 85s anymore) in a tight, solid cab like a Mesa Stiletto or an Orange. The Orange is actually the only V30 cab I like, although I still haven't tried one with my amp. (Bulb, we need to talk.
)
The stock rectifier tubes are nice for leads, but too mushy for rhythm, IMO. I use the silicon didoes, and the "bold" setting. Oh, and change V1 to a TungSol 12AX7. Immediately. Then put a good TS-style pedal (insert JoeOvChaos recommendation here
) in front.
As to how to set the actual EQ, put the bass knob where you think you need it, then turn it down. Noodles' "start at 12:00" approach works well, but start the bass about 10:00 with all the others at 12:00 - otherwise, the bas can get overpowering very fast. I use channel two for leads, since the presence isn't as aggressive, and channel 3 for rhythms.
Most of all, though, enjoy it. That's an excellent price on that amp.
