whats a done deal?

you don't own any decent guitar amps or a meter for that matter.

you haven't got a clue
of the differences.
and all of the guitar players here are try to tell you they are different.
they are different.

so tell me
mr rocket scientist
what is the over pressure of a 1980 Marshall super lead ( hot rodded for 6550's) on 7 with a 4x12 cab a fuzzface and a octaver?
using what ever guitar scott has?

of course you don't have clue whats that like you never tried it.

Don't get it twisted JCP. There are lots of different tones, gain structures, OD harmonics that make amps sound different but none of it affects the relationship between output watts and SPL on a given speaker system. That relationship is fixed in stone. It doesn't matter who built it or how they built it.

If 1w= 100db, 10w= 110db, 20w=113db, 40w=116db, 80w=119db 160w=122db and so on until speaker compression limits acoustic output.

Done deal, high school physics 101 with zero weasel room.

Put an SPL meter on it and measure it. Depends on the exact output wattage and the speaker system efficiency @1w1m. If you carefully measured both I can give you an answer. When you test it with an accurate SPL meter you will magically see the same number unless speaker compression limits acoustic output at full power. Simple math with no magical mythology.

FYI: I'm not actually a rocket scientist. My dad was though...

what your talking about, is the recent chitter chatter thats gone about over the last couple of yaers about wattage selection, in amps.

and in one context this is basicly true.

take gtzip for instance,
he has a marshall Dual super lead
you can buy it 50 watt or 100 wat.
because in the preamp stage it is basically identical
except in very singular circumstances the amp will sound practically the same volume on 10 even though there is a 50 watt difference between them.
I don't know which he has but I'm sure he knows what I'm talking about.

anyone who bought mesa mark series amps know this
weather you got simul or the 60/100
why? because all other factors are equal, in the input output stages.

decibel comparisons mean nothing in this conversation
and no one has any readings to compare.

dose anyone play the DSL 100 on ten?

absolutely not.
so who the hell knows what wattage output anyone is using?

Thread jack alert JCP. I thought we were discussing amp loudness. Loudness is measured with a SPL meter and expressed in decibels. Input and gain structure are a different subject than amp loudness altogether. See here:

"yea you would have to have a big room for that thing. I can't see turning that up at all where I am.
a very different animal all together from a JTM 45

like I said I can turn this about 4 to 7 or so and I don't turn the guitar up past 7 or so.
and I play this in my studio, about the size of a small bedroom.
despite what johnnny7 says there would be world of difference in volume. "

The bold portion would be the mythology part about loudness.

how much money have got in your wallet?

A couple $100s, I had an acoustic gig last night. You are not getting any of it though.

too bad

Come on Folks, no need to fight about it.
Just state your case, let us all read and make our own conclusions.
The energy you spend fighting could be better spent playing or writing your magnum opus.

Remember what I say about the desiderata?

I play a MIJ strat, it's an 80's RI of a 54 strat, I think? (FXXXXXX)
See I don't really know. It was an eBay score.

I bought the neck for 100$ in one auction and was bidding on the body, when it hit 60$, the guy stopped the auction and I about lost my mind.

Later I found out that he had realized I was bidding on the body and stopped it so I could keep the whole guitar at 160$. I even got a fender soft case for it as well.

It's a slim V, 7.25", rosewood neck, black, plenty of scars, old style tremolo (which I do not ever use). (I sink all tremolo's flat to the body and use the 5 spring setup/lose the back plate to increase sustain.)

When I bought it, the guitar had never been strung in the last decade.
As soon as I strung it, it called to me...loudly and clear as a bell.

I never played another instrument that was so quintessentially me.
I feel like someone is stuck in the guitar and they do all the playing.

I often say it was delivered to me by my "guardian angel", because it's not pretty but it sounds like a million dollars and although I have another MIJ strat, I've never played a guitar that was even half of what this one is.

is this the choke you need JCP, back on page 1 you and Slacker were talking about putting a choke in the circuit somewheres.. Scotty said I'm simple so bear with me.. I have tons of analog radio parts, coils, chokes, transformers most NOS in original boxes..

I admit it i dont have a freakin clue... all i know is that when i turn the knobs a certain way, the sound is less painful than when i turn them a different way

An old marshall is indeed very loud.

I have an old Sunn Model T, which is kind of a Plexi clone in my opinion, very clean amp that hardly ever breaks up, I still have it, it has 4 6550 tubes, and the tech that used to work on it said it developed somewhere in the neighborhood of 180 watts, in order to get it acting right I had to turn everything on it in the 7 range, its one loud mofo. I used an old Sholz Power Soak on it and it was still loud, unless you choked it down all the way.

Take an Ampeg SVT amp, it has a compliment of 6 6550 tubes, its rated around 300 watts, monster amp, they get extremely loud.

My current Mesa Triple Rec, i have loaded it with 6 6V6s, and i run it on half power, it gets great breakup at a manageble volume level, but it has a master section where I can get it in check.

I dont know about readings on a SPL meter of those older amps, but to my ears they are way louder than the more current amps, side by side my old SUNN amp is noticeble louder than my Triple Rec, Ive put them outside and checked them out.

I just added an old Carvin Combo, 100 watt combo, its loaded with 6L6s, and its extremely loud, but I know it cant hang with my old Sunn, and couldnt hang with any of the old Plexi Marshalls, for sheer volume.

What everyone needs to remember is that the old Marshall were developed in the days when guys were starting to play larger and larger gigs, and pa systems just werent worth a crap, so guitarist would use a couple of Marshall stacks to play in halls with 2-4000 people, who needs a pa system.

Anyway, just my 2 cents on this subject.

S'OK, Grant. As long as it doesn't hurt when you pee.
