    Default 4, 8 or 16 Ohms?

    I've never been able to find out what I should set my amp at: 4, 8, or 16 Ohms. I just have it set up in about a 11 X 11 room, and don't play gigs or anything like that, just jam at home.

    So what's the best setting for me, or does it really matter?

    You've got a tube amp, right? And what is the impedance (in ohms) of your speaker cabinet?

    It should match your cabinet, if possible, and it does make a difference.

    Yeah it should match. If it's wrong, it's very easy to tell if you don't have a tester. Just have your guitar plugged in, set the amp master moderately low (just enough so you feel it), and run your eq settings around 6 or 7. Play some open chords starting at 8 ohms, then click the selector over to 4, and play the same chords, then back to 8, then to 16. The fullest most rounded sound will be the correct position. When wrong, the sound will be thin, or drop off significantly in dynamics. I use this technique on mystery cabs in rehearsal rooms somtimes when i don't want to lug my own cab around occasionally and it works like a charm. Just remember to keep the volume low, or the amp can really pop and Iv'e heard the sudden change under load can fuck a tube.
