what would happen if I ran my 50watt Marshall head on less tubes than normal?

I'm missing something... I always saw the "master volume" as an independant volume, seperate from the "volume" that cranks the power tubes. What am I missing?

On a 2 or 3 channel amp with 2 gains, 2 volumes, the extra volume control that controls everything is often called a master volume, although it really should be called a global volume

the DSL should have a "global volume"... that was what I was trying to say earlier.

I didn't realize that there were two master volumes on the DSL (one for the dirty and one for the clean). I just assume that volume means volume :laugh2:

thanks for clarifiyng !

Why not get a 2x12 cab for it??

I split my cab so it is playing like a 2x12...

I also would love the idea of a "global volume"

Why not get a 2x12 cab for it??

What good would that do? 2x12 vs 4x12, given the same power being thrown at the cabs, should only be a +/- 3 db difference.... barely an audible difference in volume.

its a spread thing - whats louder - 120db pointing at your ankles, or your ears

+1 if the amp ain't running through a P.A... its best to have it angled properly.

Are you talking about an angled cab now?

The further you get from the cab, the less merit the "dispersion" argument carries. Besides, 120 db is loud no matter where it's pointing... even if you're standing next to the amp. And the further away you get, the less focused the source is, and there will be far less perceived volume drop in the change in angle.

I understand the angling of the cab, but going to a smaller cab or angling your cab isn't going to make a big enough impact on the volume. You'll still want an attenuator of some sort.

120db is standing in front of a large PA system during a loud concert heh- i meant it for illustration..

hotplate is still my recommendation though..

some guy at the hiwatt forum ran his hiwatt DR201 full out through a fullstack and measure 118db next to the speakers

in my old band my guitarist had a 400 watt fender amp and they took out half the tubes it sounded like cr@p like a lot of noise im not sure as to why though

400w tube amp!!! wow thats a biggie

you cant pull half the tubes in all amps and you have to which tubes to pull to make it work right.

get that Van Halen master guy in here (is his name VhHolic or somethin? lol)......he made some clips of his marshall with only 1 power tube in it, and it sounded awesome.......find his name in the user list and send him a PM, he may be able to help you

How would that work?

Yap yap well throw in two G12H Celestions and it will be just fine if you like the sound of those.
Plus maybe the DB measuring is not the way to go on this, why not just use the ears and go for the best feel, two 12's give enough and is not as thumping as a 4x12, and if you get an openback one it will spread better without being too loud.
The speakers will move more and give a looser feel, but that is just how I used to do with my big amps.

Currently there are four G12T-75's in my Cab (Marshall 1960A series)... thought about changing the speakers or the whole cab for something with Vintage 30's in 'em. THe 75's are a bit harsh and loud speakers, IMO. I don't find much warmth in them.

How does the attenuator hook up to the amp. Is it just a couple stereo cables and atteched between the head and the cab, or is adding one more complicated than that?

How about throwing THD Yellow Jackets into the mix.

An adapter that allows you to run other tubes that will lower your output of the amp. IE: Allowing one to run EL84's in an EL34 or 6L6 amp.

I havent' tried them, but there seems to be many out there running them wihout any issues.
