    Hey guys,

    Looking for some help understanding amp specs, specifically for the V-4B Reissue. I know they don't mean a whole lot, and my ears have already told me that the thing sounds great. But I'm curious how to read these:

    > Output Power Rating : 100W @ 8% THD+N @1 kHz for 2, 4 or 8 Ω loads

    I know that means the amp starts to break up at 100W, but what's the "+N" bit?

    > Maximum Gain : 64 dB @ 1 kHz, tones centered/-3 dB @ 14 Hz and 15 kHz

    Is this the loudest in dBs that the amp gets running a 1kHz sine wave?

    No. Your actual loudness when playing will depend on what cab you're using.

    Yea, I get that, but what is that “Max Gain” measurement?

    I'm not an engineer but I think it means the in to out ratio, in other words your max gain from the 1000 hz signal when plugged in is 64db, it's the amplification factor nothing to do with how loud the amp can get, this amp is rated at 8% distortion at 100 watts into 2,4 and 8 ohms, a cab's efficiency determines how loud it gets. "N" means noise (thanks to google). If you can get the amp to distort at any volume level you have enough gain because it's going above rated output.
