My friend just gave me a H & K RED BOX for guitar direct recording - speaker jack out. It's the MKII version. Are they any good? I've always been one to demand a mic on a speaker cab 99% of the time.

Thanks,
Kevin
 
Personally i don't like the sound of the Red Box......everything else than a speaker simulation.
IMHO an older Marshall SE100 sounds much better (in case there's no possibilty to go with mics). You'll have also the possibility to simulate the mic axis (0°, 45°, 90°)....nice feature. I was often asked by some other engineers, what kind of mics i've used for that fat sound out of my old fender vibro amp.

I did some studies to a lot of cabinet simulators, the se100 have the most high order low pass filter.
behringer have a cabinet simulator designed by Jurgen Ratt the GI100 it seems to be very good too ,but still I can´t find a schematics or pcb pictures of it.
 
Are they any good?

I don't understand posts like this. Since you have it in hand, why not just try it and draw your own conclusions? How you feel about it should matter more than the opinions of strangers on the Internet. My idea of good guitar tone might be the complete opposite of yours.

Sorry dude but I like other opinions. Not to mention, others opinions can turn you on to cool tricks or mods & possibly things to avoid.

here is the schematic.
not seems to be a high order low pass filter . some notch there.

That's the newer RedBox Pro, passive model.
The older ones had active circuitry (covered with black epoxy), a quad op amp and no o/p xfrmr.

Here's the H&K Cream Machine with the active cab sim circuit at the top.

Keep us informed ! :thumb:

How did you tackle the heavy stuff on the third page ?
 
I understand that the page 3 is not mounted on the pcb. I put all the rest on the pcb , if I don´t want something just I don´t put the parts.

personally I don´t want the attenuator part ,
 
Do you guys think I should change the topic title to get more input about these direct recording devices in general?

Just tell me how & it's done

:green:

I still haven't had a chance to try the Red box mkII yet but it seems the se100 is more of a sought after model?
 
While I haven't heard the best speaker-simulator filters a la SE-100 & Palmer stuff etc etc I have the feeling that they might be obsolete now digital modelling a speaker cab has come of age. Please correct me when I'm wrong here, it's just a feeling based on a few specific observations. But my modest Beh. V-Amp was so many steps up from what I used before that I haven't used such filters since.

I see, not that big stuff. You won't get the amp-reactive load interaction then of course, but I dunno how big of an influence that really is here.
 
.......probably clint might be right. Just know digi modelled amps+cab simulations from line6.

But there never was any sound like a "Fender Vibro Amp without gain pot, master 3/4 full" driven by a srv strat with texas - single coils direct into se100->isa110->isa115->daw! :cool:
I've used that mostly when i had no time for mic positioning and needed a fat crunchy blues sound.

But as Dave mentioned earlier: The chain above will work fine, but maybe just for me (and stevie ray :green:)
 
I try the pod II and it don`t sound so great at least the factory presets.
currently I`m using a clone of a ENGL tube preamp with the marshall cabinet simulator drawn by ed rembold . it sound good for me, I use it for record demos .

I try the speakers cabinet of the guitar rig software but finally I use the circuit.

probably the digital stuff is more precise and can make a more exact copy of a cabinet, simuling the comb filter formed for all the reflection inside the of the cabinet and the saturation of the speaker at high volume. but if a cheap 3 filter simulator do a close responce I prefer the analog stuff.

I see, not that big stuff. You won't get the amp-reactive load interaction then of course, but I dunno how big of an influence that really is here.

my tube power amp is 200Km from here so the preamp is conected direct to the cabinet simulator . I don`t need the reactive load :wink:
 
I'm surprised that there isn't anything else like the mes@ rect0 recording pre. The combination of a tube preamp and speaker simulator seems like a winner to me. It would be the ultimate Pod if it wasn't $2000.
