Free Fender amp Impulse Responses

Postby raffguitar++ » Wed Mar 08, 2017 8:30 pm

Hi Folks,

I'm posting these over here because the topic was brought up in another thread, which had already gone off-course, so I figured I'd try to keep things clean.

These are free impulse responses I created back in 2011 or so and had uploaded to Guitarampmodeling.com. They are of two amps that I unfortunately had to sell: a 1971 silverface Fender Deluxe Reverb (with original Jensen speaker), and a blonde Fender Blues Jr ca.2006

Fender Blues Jr:

Fender Deluxe Reverb:

md5 checksum for Fender Blues Jr.
http://www.yourfilelink.com/get.php?fid=1331133

md5 checksum for Fender Deluxe Reverb
http://www.yourfilelink.com/get.php?fid=1331134


OK, the checksums might be a bit overkill, but I figure better safe than sorry, right? Plus I need to practice my command line as much as possible. :wink:

Hope you find them useful - Enjoy! :)

Forgive me guys but how do we use these files. With Guitarix? Will I need another program? Is this in essence a sampler file for guitars?

You need a convolver. Consider this for example:

Hi,

This is a huge topic, but put very simply, an impulse response is like an "audio snapshot" of a particular acoustic space (in this case, a particular amp cabinet with a particular microphone set at a particular distance in a particular room). All modern amp simulators, from AmpliTube to Line 6 to the Fractal Axe FX, use convolution to recreate the sound of a certain amp cab/speaker/mic combination. Impulses are also used quite extensively for reverb as they give an incredibly realistic sound. You can search all of that out if you're interested, but here's a quickie tutorial to get you up and running:


Guitarix has a built-in convolver, but it seems to be intended mainly for reverb impulses not speaker cabinets, so IDEALLY you want to use a zero-latency convolver (like the LSP one linked nearby) or Robin Gareus's zero-latency Convolver LV2 plugin, because I think they're designed for shorter impulses (...although in all honesty I don't know if maybe Guitarix's convolver is zero-latency as well..?) In any case, we'll use the one in Guitarix as an example;


* Start Guitarix. Make the rack visible by selecting "Plugins > Show Rack".
You should have two rack modules - the "input" module (noise gate, compressor, mono level out, etc) and the amp head. Since these impulses are mono, you're going to use the Mono convolver. Go to "Plugins > Mono plugins > Reverb > Convolver".

* (Just in case, make sure that the Convolver is AFTER the amp head by clicking "Order" and click-dragging the convolver after the amp if necessary.)

* On the Convolver panel, click "Setup" and use the "File" button to navigate to one of the Impulse responses. Just a suggestion - start with an impulse that's relatively close to the speaker and on the cap's edge, like "DlxRev-PE50SP-CapEdge-1in.wav" in the "Fender_Deluxe_Reverb_1971/Shure_PE50SP_(Dynamic)" folder.

* Set the "Mix" of the impulse to 100% wet. Click the "Gain" knob's power button to activate it and bring it down a bit; some impulses are louder than others and it's best to start low and balance volume later as needed. Click "OK".

* Now just lower the amp head's volume to get a clean sound, which is what the Fender amps are generally known for..or crank it a bit for a bluesy tone.
Try setting the "Clean/Dist" knob all the way clean, "Pre Gain" at 12 O'clock, and the "Drive" to a moderate setting. And for the Deluxe Reverb, you might want to add a little "Bass Boost" and "Presence" to add more authenticity.

------------------------------------------------------

Now of course, where Guitarix really shines is with heavy guitar tones, and there is a metric TON of free guitar cab impulses floating around the net. In fact, I think someone at guitarampmodeling.com had put a link to a massive collection that someone put together in one huge archive a long time ago..I'll have to look, but it's probably even BIGGER by now! :shock:

Anyway, hope this helps :)

Of course, the guitarix Convolver's are zero-latency one's. :wink:

Well, while this is true, most people simply just didn't know how to make guitarix shine on clean tones as well.
The fact is, that guitarix is modular, a way more modular then any comparable analogue gear will be, that would make it a bit harder to get what you wont, but open as well a couple of possibility's.

So, to get a nice, clean amp tone, you should involve the BiQuad filter from the Tone Control category, and put it before the amp (tube emulation), that will smooth the input in a way that it reduce the drive in the tubes ( it act as a amp input buffer), so that they later starts to overdrive.
And of course, like you've said, like with most other amp sims, you need a IR file, like your Fender Blues Jr. one, for the convolver behind the amp to get the classic sound.

Wow that's cool. I didn't know we can do that. For reverb I use OvertoneDSP RVB500 which is ok but if I can find ir files that sound better for vocals. This is interesting.

as a stand alone convolver, LSP is the best for Linux and works amazinly. The built-in one in Guitarix is awesome too.

Hi tramp and ++,

I am gonna try your tricks later when I am home.

Thanks :D :D :D

Ahh, interesting! Thanks, I'll have to try that and tweak my settings. Still quite a few modules I haven't played around with yet.

@dsreyes: Yeah, depending on the quality of the impulse taken, IRs are usually much better sounding than algorithmic reverbs. The only down side I can think of is that they use more CPU. (..sometimes a LOT more). For reverbs, search for Bricasti (M7 ??) and Lexicon PCM70 in the freebie archives.

@Arthurx: You're welcome! Have fun down in the sonic rabbit hole :lol:

Hi. I think the llinks have expired. Anyway you can repost these? Thanks much!
