Yes, I stand by my assertion that "Using an attenuator with a modern circuit will simply be taking the same sound you would have had at low volume from high volume back to the low volume again. No change in the breakup/distortion just the volume."
Last time I am going to tell you BP...I am not a tech. My observations are based on myself playing the amps I speak of and in the manner I speak of. I have played (and still do if I am too lazy to bring a plexi to rehearsal) JVM, DSL, TSL and a Mesa Triple Rec numerous times. Those amongst other high gain amps such as 5150's, Diezel and Diamond. Some of those are available to use at the rehearsal studio I play at and alternately I have friends who own others which I have at times borrowed and played loud for extended periods. I repeat, I play very, very loud and am not talking noodling for five minutes on the amps I speak of in a music store or someones house at low volume.
Again..."No change in the breakup/distortion just the volume"
IME, fact.
NMV plexi circuit?
Play it on low volume and then play it loud and there is a MASSIVE change in the breakup/distortion.
Fact.
Now use an attenuator on a plexi, turn the amp way up and dial down the attenuator to low volume. Then try the same scenario on a modern high gain amp.
Get back to me and let me know which amp had any discernible effect from the attenuator being used.
I think iron broadside is speaking more of what I would personally call "blooming" in regards to making the power tubes come alive. And I just don't hear the same "blooming" of power tubes in the modern high gain circuits when those amps are turned from moderate volume to extremely loud. To my ears those amps just get louder as you turn it up. And I have certainly never heard gain increase like it does on a NMV amp when doing so. As I mentioned earlier that "bloom" is still evident (to a point) on earlier MV circuits like a JCM800 or JCM900 so I don't think the MV itself is a factor. I believe it is the circuit itself and the way the power section is designed to run clean on a modern high gain amp. And from what I can understand given what I have researched on my own as well as heard from more knowledgeable people than myself, it is an intentional design to accommodate a tighter gain structure primarily derived from the preamp section in multi channel amps where an alternate clean sound can be achieved.
My suggestion?
Play the amps yourself.
Listen B/L I don't really care how many times you tell me you're not a tech.
I merely wanted to know if I ( or anybody ) should get an attenuator to use with our DSL series amps.
You asserted that because of the circuitry used in DSL amps there would be no point.
However, because you are " Not a Tech " I guess it means that you do not have an extensive knowledge of the circuitry involved. So I guess only a tech will be able to confirm whether your assertion is factual.
Thanks for the suggestion but I don't need to play the amps 'cause I already get a " wicked " sound out of my DSL40C without the use of an attenuator with volume on 2 and gain on 10. Perhaps my sound could get " wickeder ( lol more wicked ) with volume on 3.5 with an attenuator. At this point we have reached an impasse.
My thanks to your good self and Iron Broadsword for sharing.
