    i know different pots have different tapers but wondering specifically about my 93 TRRI. Sorry if it seems
    Like a dumb question. I ask because I was playing an outdoor gig last night and set to volume on the amp around 4 and rode the guitar volume.
    onnlouder songs while playing lead, I noticed the guitar was nearly wide open and was thinking it should be a lot louder than it was. Maybe playing outside had a lot to do with it.
    Anyway, it got me wondering if a twin will get louder the higher you set the volume as I know some amps don’t.

    Mine sure do...don't see why it would be any different for yours. Might want to investigate those power tubes.

    Unless you have worn out tubes.

    The problem with apparent volume (and especially outdoors) is the sound disappears all around you and no reflections. So you think you're quiet when you're nuking everyone around you.

    Use the layback legs and if possible get it eight-ten feet from you pointing at your head.

    Thanks for the reply’s. The tubes are pretty fresh and the amp seems to be working well. It was probably just
    Me. I will use the tilt back legs next time and see if there’s a difference.
    I sure don’t want to be nuking anyone! Lol

    Yeah my TRs definitely get louder past four. They're capable of some pretty extreme volume when ticking correctly, so easy to not notice when there is a problem.
    Simple test, put a Deluxe Reverb next to your TR, plug into both of them and start cranking them up. If you don't get to the point where you're checking the DR to see if it's even turned on, something is wrong with the Twin. :)

    If they do get louder past 4 you probably won't notice it because you'll be deaf by then...

    Or the sound man will have already killed you.

    One of my bandmates back in the early 80's had a sweet silver face twin he paired with an equally sweet cherry sunburst LP Deluxe. Every New Years Eve at midnight, (if we weren't playing) he'd wheel it out on his balcony, turn it up to ten and strum an open E chord. He'd hold it for 30-45 seconds, then shut it down. When asked why, he'd say "Because it's so freaking LOUD"! He was right!

    What does it matter? Your organs are liquified by 3.5.

    Mine didn’t.

    Of course, it was aimed at my bassist and he disintegrated somewhat messily. However, his 1974 P-Bass was just fine after we wiped it off.

    Everybody else in the band cranked it up, too.

    Great point..just got some silverfaces & the tilt back legs have brought some volume down for me(no compromise in tone..still at 5 vol) it disperses so well

    In my experience, even the loudest amp is not loud enough when playing outside.

    My ‘74 SFTR just keeps getting louder up until about 7-8. Beyond that point, it does develop some natural OD and compresses a bit.

    I think. Or maybe it’s my ears.

    It will ! On my late 70s SF, I set the master at 10 and increase the volume accordingly, and I notice exactly what @thegeezer wrote just a post above mine :

    On a Blonde Ltd. Ed. 65TRRI, here are the values that I recorded on a sample last year :

    measurement schedule :
    [​IMG]

    Amp model and settings :
    [​IMG]

    At rated power 85W RMS - pure clean :
    [​IMG]

    At 90.25W RMS - the onset of clipping is barely visible :
    [​IMG]

    At 100W RMS - clipping onset is reached :
    [​IMG]

    Sure, a Twin-Reverb BF, SF or RI indeed "talks loud and clear" ! :D

    Just "open the valves"... ;)
