how do you guys record head output for use with impulses?

Im getting tired of the pod tone and want to record the output of my dual rectifier to be used with impulses, but im not really sure what the deal is with making a dummy load and dont want to kill my head messing around. What would be the best way to go about this?
 
A) use a speaker and put it in another room. (although I'm guessing this isn't an option for you)

B) buy a dummy load such as the THD Hotplate.

DO NOT run your head minus a speaker or a quality dummy load. burnination.
 
what output do i use into my interface though, a preamp out or poweramp out?

i ask because a while ago at my friends house we tried with his roadking slave out but it sounded really shitty for some reason, was i supposed to use one of the speaker outs?
 
YIKES! Don't use the poweramp out, that is for speakers!

You should be using a line level out, usually a dedicated line out from the amp, or a line out from an attenuator/dummy speaker load like a Hotplate.

If you're using a line out from a tube amp, you'll still need to leave the speaker hooked up. This is very important.
 
Ok for my Dual Recto, what I do is have the FX Loop SEND go straight into the interface. It's suppose to sound like shit...it's only the preamp...then you apply the impulse response of a cab using Boogex or Altiverb or whatever you are using and that signal is "passing through" a poweramp/cab/mic/room and it will sound normal :)

When using your head for this, ALWAYS, no matter what the circumstances, have a speaker cabinet hooked up. You don't have to have the amp cranked, enough to hear it, whatever, but using the FX Loop SEND there should be a level pot for it so just crank that up and you'll get a nice and hot signal to your computer to run impulses on.

For using it with a dummy load, I would check out Weber stuff. You can get an attentuator that does more than the THD HotPlate and costs HALF as much. :) It's called the MEGA DUMP. :lol:

The THD hotplate has worked great for me.
I just picked one of these up a couple weeks ago. I'm going to have to try recording something direct out of it and experimenting with different cabinet/speaker impulses. I'm very curious how it will sound!
 
THD HotPlate is overpriced, IMO. The Weber MEGA DUMP does the same thing, works for all ohms, and costs half as much....also has some extra features that the HotPlate doesn't. Just my opinion.

correct me if im wrong, but if you switch to the fx loop and the send doesnt go back into the return, wont nothing come out of the cabinet since the poweramp is not recieving the signal which is now going into your interface?
 
I dont' question it, but yes, it does still go to the cab. I guess because the RETURN is not being used....I dunno. It works this way for all of my heads that have FX Loops.

is it reliable as the thd hotplate?
I heard very bad things about marshall powerbrake, even the name says it all: it will "break" your amp ehehehh.
The only power attennuator I heard is working good is THD!
anyway I'll read reviews of this Weber MEGA DUMP!

You need a DI box for the signal form SEND, am I right?
 
@elephant-audio: Do you own one of these mega dumps? I am interested in purchasing one, their price looks pretty fair.
 
Yeah by the way, there is something I don’t really understand with these dummy loads. Do you always have to put your cab after them? Can’t you just get rid of the speaker when a load is plugged in the amp?
 
Ok, first off, yes I own the MEGA DUMP. Secondly (@ miche), no you don't have to put your cab after it. The attentuator basically "harnesses" the output of the amp, so it makes the dummy load. You can either hook up a cab, and attentuate the level of the amplifier output, or have the output of the attentuator go straight to your DAW for a "line output" to use speaker impulses on.

The thing you have to understand is that without a load (either dummy or actual speaker cabinet) being placed in the output path of the amplfier, the power will be looped around in the amp. Basically. So if you have, for instance, a 5150 or XSr™, then you have 120w of output being looped around and around inside the amp. This is what causes transformers/tubes/fuses/etc. to blow up. With a power attentuator, i.e. dummy load, or a speaker cab, that 120w is being fed into something and released, therefore not being looped around inside the head. When using a power attentuator, then, no you don't need to have the cab hooked up, because the HotPlate/PowerBrake/MEGADUMP that you are using is taking care of that end of business for you. :)

@ Atheist - I am using interfaces that have instrument inputs, which basically are the same thing as a DI box. I've never used the FX Loop SEND into anything without an instrument input, so I don't know if a DI box is needed, to be honest.

@ kaomao - I was turned on to Weber products by DSS3, and I ordered one soon after him telling me about their products. I'm extremely happy with my MEGA DUMP, and we actually use to rent a HotPlate religiously from a place here for the purpose of getting cranked tone at lower volumes. The WEBER does the same thing, but can handle all OHM loads in one unit, has some eq options on a couple of models which help tremendously because using attentuation the eq of the sound is different..., costs half as much, and is just as reliable. The thing with the THD products is they are advertised much more..in fact I've never seen a Weber advertisement. Please don't correlate advertisement/mainstream with reliability and quality, it just costs you more in the end man :)

@elephant-audio: thanks a lot for all your details, it seems you convinced me! obviously, happy users make a better work than expensive advertisment. I will try to reada few reviews from that mega dump here and there and probably order mine before the end of the week.

yeah but the hotplate is puuuuuurrrrrrrrrrrrrrrrddddyyyyyyyyyyyyyyyyyyy ;)
 
Hello guys, been a lurker here for a while, great forum.

Reading through this post has caused me to soil myself a bit, so I'm looking for a
wee bit of advice.

I've been messing about with impulses for a while initially with a toneport, but now I'm running through my Randall V2. I'm probably asking for trouble cause I aint using a dummy load with it (no cab either) just straight from the fx send into the desk.
The heads got a line out on it as well but it's frankly balls.

I was getting some good results from the fx send but now you've all got me worrying that I'm about to blow it up.

Should I stop now and buy a dummy load before I melt the bastard?:OMG:

Cheers guy's.
