Want that VH1 tone? You gotta slave it!

[mr.twistyneck]

if those are chassis mount type resistors, go get some thermal goo and a junk piece of flat or finned aluminum and make yourself a heat sink. it really helps!

I love it! A gratuitous shot of the (ahem) "resistor mod"! Classic!

For those of you who havent already done so, make absolutely certain that you click the link at the bottom of twistyneck's post and start reading. It will definitely make you forget all about THIS post, that's fer sure.

So have we given up on the slaving mod????

[rgalpin]

i think in order to get the cerrum mod up to stage volume, you have to slave it. so, if yer in the camp that says that the live bootlegs from OCT 78 sound "just like the record" AND if you think the cerrum mod has the VH I sound - then you are probably saying that it is a slaved setup because this mod is not loud enough until you slave it.

[ericopp]

Rob is right. We have NOT given up slaving; far from it!

Remember the old Ed quote where he says he uses a combination of two Marshalls, one of which is lower power than the other? IMHO, he's referring to the "weaker" one which is rigged with the resistor across the primaries mod (AKA the "stick of dynamite" AKA C*****'s mod AKA Twistyneck's mod).
THEN apply the load box to the speaker-out and the resulting line out to the normal power Marshall head(s) to amplify the signal to anywhere from small club to arena level.

Voila! The EVH club/VH1 sound at any volume!

Add EQ, phase, echo, etc. as desired.
Absolutely NO DISTORTION pedal is needed!

what kind of pre amp tubes are those? red inside? or are they ON FIRE!

[Ray]

The Palmer PGA-04 has that in it, it's a load box and uses Tungsten filaments as the reactive load. Great box to use and great control.

Ray

So what is the best device for collecting the first amps load and turning that into a low level signal for input into second amp?
Weber mass??
Palmer??
Reamp??

Thanks

i think the most important thing is that it be a reactive load so that the amp acts like it's seeing a real speaker. palmer doesn't provide a load at all if i remember correctly.

[rockstah]

so is reactive load the same thing as a non-inductive load?

[leadguy]

A reactive loads circuit will make the amp REACT (reactive) to the load, unlike pure resistive dummy loads. A reactive load can be made up of inductors caps and resistors.

damn!... i just slaved a 68 spec amp build into the normal channel of my 78 that i rebuilt and is running a plexi spec and it sounds killer! instant headroom/hifi! ....instant dutch treat.

running a trex replica delay between the amps. again it sounds killer!

the big silver box is a line out box i built. it plugs into the first amps speaker out - works great!

i haven't even messed too much with the poweramp amp. i figure i will removed the bright cap on that amp and try the bright channel input.

so much more flexibility now on the tone as well via the second amps controls.

on first run i had it setup like this: ( no delay )
amp#1 everything dimed and into a power brake set to load
( the power brake sounded better as load than the big 300watt arcol resistor u see in the picture. )

from the line out box into the hi input of the normal channel.
amp#2 settings:
presence 6
bass 5
middle 5
treble 5
bright volume 0
normal volume 2


i would go as far as saying,..
after all ive done and been through,..
having had this setup in my hands,..
Edward did run this setup. ....you all NOW need TWO Marshall's.

For what you guys are doing a fixed load, resistive load is probably what you want but remember it does change the frequency response of the amp so it isn't the most transparent solution for someone who likes their tone but it is too loud. A reactive load that mimics a speaker cab is better for that.

[leadguy]

I agree with Rockstah. I don't really think the C e r e m resistor is what Ed used although it gives a good sound but reamping with the right amps and maybe playing with a variac up and down will get very close to Ed's VH1 tone thing.

Mark let me get this right. You used the Power Brake as the load pluged into one speaker out jacks and you pluged you line out box (47k resistor and 5k pot) into the other speaker out jack. Then out from the load box to the input of the second marshall. Is this right?
Also how do you set the Power Brake to load? (dial all the way to left?)

yes all the way to the left is load on the power brake.
yes one speaker out is used for the load the other speaker out is used for the line out box. u have it correct about how i have it set up.

i have the line out pot at 4 or so in my setup.

i ended up just putting it in its own box rather than in the amp. ( i be adding it inside the amp permanently now. )
