    For those with master volume amps, I have to ask do you really think your amps sound that great cranked all the way, or is that just the general saying around here?

    Both my JMP 2203's, one with EL-34's & other with 6550's, sound glorious with the MV from 2.5 to 4, then exponentially worse from 5 to 10 (the EL-34 version not as bad as the 6550 version). I just never see a reason to push the master volume past 4 seeing as I'm already reaching power tube breakup by then (or at least I'd like to think I am). I can crank the volume all the way to 10 without running the risk of bothering neighbors due to my location, but I just see (or hear) no reason to.

    I've run them on 4x12's loaded with either G12M-25 (Pre-Rola Greenbacks from '69), G12T-75's, or Vintage 30's. Perhaps I need to try other speaker configs, because at a MV of 5 these cab speakers aren't sounding all too happy.

    Just curious and would like folks' opinions, not meaning to insult or flame. I couldn't imagine pushing a non-Master Volume amp and expecting a decent tone while heavily pushing any of those speakers without an attenuator. Perhaps there's something wrong with my amps, or ears? :confused:

    I found that on every marshall I had, the sweet spot was around 6-7 on the master, except the plexi which I prefer dimed.

    I had a JMP 2203 with EL34 and the sweet spot was at 6 for me.

    I normally run my gain at 3/4 and my volume at 1/2. Gives sweet tones :)

    Yeah, anything above 6-7 for my 2203 is just too much. However, it is a balancing act; gotta play with the pre volume as well.

    I usually keep my pre-amp on 10 & boost it more with an Analogman modded Maxon OD-9.

    Master Volume on 4 is the sweet spot for me when working with a crunch/overdrive tone.

    I have a JVM, and it sounds like dog shit with the MV past 5. 4 is really the sweet spot, if you ask me.

    On the MVAs I've played, 4-5 seems to be the sweet spot.

    Also, I've always used Celestion G12K-100 speakers since forever. They've always kept their composure, regardless of how much juice I've put through them.

    On my Mesa, I set it on Tweed and the Master Vol @ 5.5... I usually fiddle the channel volumes to find that sweet spot.

    I have an AFD and my master rarely leaves 10. BUT, if I also crank the attenuator, I get a ton of almost uncontollable feedback. I don't really even need to turn it past 5, even at stage volume.

    With the EPA on the AFD, this is where it shines. It is easy to get output tube distortion at low volumes. But it is really cool when your moving some air and you get the speakers more involved. I like the Master around 7.5 and the gain around 4 to 5, Then I adjust the EPA for the loudness. If I want it really quiet with tubes screamin, like late at night when everyone else is sleeping, I'll engage the FX loop and have it attenuate some more. This is the most amazing amp I've ever played, any level of preamp or output distortion at any volume level. Marshall should put this on every amp.

    Are you talking about the EPA? I have never experienced any feedback that I didn't initiate first, at any setting.

    Nah, I never dime the master volume (I have a stock JVM 410H).

    I use a 2X12 with two Celestion 90 watt speakers wired in series (180 watts total), and I never got a "I can't hear you...turn it up" complaint. Thick, powerful, clear projection of clean, crunchy, moderate gain, and high gain tones at almost any volume. I feel spoiled.

    preamp around 7 or 8 for LP,6 for strat,Master no more than 7 but by then it's usually killing coyotes in the next county.

    I've dimed my 1959 a few times and can't really say it sounded any better on 10 than it does on 7. I've never dimed my AFD, that mofo us just too fuckin loud. It does sound better the more you crank it though.

    Peace

    With my 6100 it really depends on the size of the room. The bigger the room the more MV it can take and still doesnt give you too much eardrum compression. I always have to fine tune whenever i move it to a new location. Its all relative.

    2.5 on the master volume on every Marshall amp sounds like utter ass ... you need to get into the realms of 7 - 8 and 9 ... My JMP 2104 sings like you have no idea when you get to those volumes on the Master, and Pre ... sounds incredible. JMP's are the worst sounding low volume amps ... lol

    Plexis sounds best around 8-10 in my opinion.

    Plexi

    I never turn a 50W head all the way up as the power valves distort too much.

    I like my 6100s at full volume with high gain - the EH6CA7s and JJ 6L6GCs have enough headroom for that. I wouldn't do the same with EL34s.

    I can hit 8-9 on my clean or dirty channel with no problems at all

    Somewhere with a Friedman Marshall & Les Paul.
    [​IMG]

    The sweet spot on my Friedman is about 4 or 5. It has resistors on the MV to tame down headroom, after 5 it goes back to fullblown JMP.

    My stock 6550 JMP 2203 i sold, but was stupid LOUD. i think the most i could stand indoors was 4 on the MV.
    Never got it outside, was a great sounding amp. At one point was going to have Friedman tweak that one too but sold it as is.

    Never played a Marshall Major but the LOUDEST Marshall i ever played was a 67' SuperBass ... was scary LOUD !!! :wow:

    Yes I meant EPA. If I get it over 5, it's really easy to have it feedback. If I let go of the strings for even one second it starts. With both guitars.
