hi everyone,

I'm using Garageband on my iMac (I will soon turn to Logic) and I just decided that the guitar sounds were not good enough anymore so I downloaded LePou's amp sims and cabinet (LeCab2). I'm trying to get a decent sound but all I can get is extremely fuzzy and much less powerful/fat than the heaviest distorsions included in GarageBand (that are not really good).

my equipment is :
a variety of guitars including a Gibson Les Paul.
an Audient Id22 soundcard.
I'm only using the built-in speakers on my iMac but I'm using them to listen to everything, from LePou demos on the Internet (that sometimes sound amazing) to my own riffs on garageband's amp sims and LePou's amp sims so for a comparison, that shouldn't make a difference.

I was used to having a good guitar, an amp and a good sound but now, it's different and as opposed to other amp sims and GarageBand amp sims, LePou is not all-in-one and I finally understood that I had three things to fiddle with :
- amp sim (stands for the amp in real life) - not too hard to deal with
- cabinet sim (stands for the head in real life)
- impulse (stands for the mic/space in real life ?)


1/ are there any specfic recommendations for the cabinet sim ?
I don't really know how to deal with phase, delay, high pass, low pass are so I'm lost.
can I use several impulses at the same time ? what for ? I basically need a real tutorial on that.

2/ what should I do with the impulse ?
use wav files downloaded on the Internet ? and what files ? I tried Marshall sounds but why would I need that if I'm already using the Marshall simulator on LePou ?
make my own files from a software ? is there a good free software that does that ?
again, I'm in need of a tutorial.

3/ any advice regarding amp sims would be appreciated too even if that part is much easier to understand for me.


more generally, how can I get a thicker sound ?
and does anyone knows tutorials/websites that would help me recreate famous metal sounds (thick and silky a la Slash, aggressive and precise a la Slayer, powerful a la Metallica...) with my LePou plugins ?


thank you in advance for any help you can provide

I'm not very good at explaining, but I'll try my best. Here are some video tutorials:


This video shows a bit on dialing your tone on an amp sim.


Basics of Impulse Response (IR)


This video show some good tips and tricks on recording and mixing guitars with free plugins. You don't have to copy everything this guy is doing.


This video goes a little more in depth with Lecab2 and various ways to make your guitar sound and feel more real. To answer your first question, you can use multiple impulses if you're into blending cabs and mics.


The phase switch inverts the phase of the impulse. It's the same as the phase button on the tracks of your DAW, which is use for checking whether the mics are in-phase or out of phase, or what elements in the sound of both mics are canceling each other out. For example, the fredman mic technique, which is basically 1 straight mic and 1 mic pointing off-axis near the first mic. When you invert the phase on one of the mic tracks, you will hear only the fizz, which is basically what's being canceled out for this set-up. If you're using just 1 mic or impulse, then you don't need to worry about the phase switch. In fact, some impulses are made in phase already, especially the ones in packs, such as Ownhammer, Rosen Digital, 3 Sigma Audio, etc. If you try to blend one impulse from one company with another impulse from a different company, chances are they are not in phase.

High Pass is for filtering the low end. Low Pass is for filtering the high end. The amount you need to filter or tame depends on the overall sound. Personally, I would use an EQ for high pass and low pass instead of the ones on the cab, since I don't know the details of the actual steepness of those filters. It's all preference.


2/ what should I do with the impulse ?
use wav files downloaded on the Internet ? and what files ? I tried Marshall sounds but why would I need that if I'm already using the Marshall simulator on LePou ?
make my own files from a software ? is there a good free software that does that ?
again, I'm in need of a tutorial.

You load the impulses into the cab sim, which is technically called a cab impulse loader. In other words, the cab sim is simply an impulse loader. I don't know the actual process of how impulses are made, but they are pretty much cab w/ power amp + single or multiple mics capture through a mic preamp of some sort.

Believe it or not, impulses make up most of the sound. You can make Amplitube sound better by replacing the built in cab with a good 3rd party impulse.

There are tons of free impulses you can find on the net. But they're not all created equal, so you have to try them and see which ones you like.

Here are some free impulses that I tried:

3/ any advice regarding amp sims would be appreciated too even if that part is much easier to understand for me.

I would say don't dial your amp sim the same way how you dial a real amp. Cuz according to one of the twitch streams from FakeSmileRevolution (the guy from the 2nd video), he said that most amp sims (digital) cannot handle high frequencies the same way as real amps (analog), especially when cranking the treble or sometimes the presence knob. Instead of adding more highs on an amp sim that sounded too dark or loose, he suggested that you use a separate EQ after the cab to boost the highs. However, this doesn't apply to all amp sims, cuz nowadays, I noticed that FSR sometimes turn up the treble knob a little bit on certain amp sims. Plus, he mentioned that the Lecto (except other Recto sims) sounds best with the presence cranked on the Orange Vintage channel. So it really depends on the amp sims, your gear, and how you handle the sound all together. Also, don't use presets.

For a Slayer or Metallica type of sound, I suggest that you use an overdrive pedal to boost your amp sim, such as the TSE 808, or the TS-999/TSB-1 from Ignite Amps. From my experience, most amp sims sound flubby without a pedal compare to their real counterparts, such as the Peavey 5150. But for the Recto or even a Marshall, you definitely need a pedal to boost and tighten the sound. From what I know, Slayer and Metallica used modded Marshall heads back in the day, and they still needed some kind of boost. Hetfield used to use a Rat pedal to boost, and an Ibanez TS-9 as a replacement after the Rat pedal was stolen. The guys in Slayer use a 10 band EQ to boost the front of their amps with a frowny face setting. You can try that. I don't know if they've been doing this since the 80's, but it's apparently part of their set-up. The only person I know that suggested to use EQ in front of amp sims in particular was Dan Swano. But it's mainly for tone shaping the DI signal of your pickups if they happen to be too bright or too dark.

BTW, these pedals are free:

TSE808 - https://www.tseaudio.com/software/tse808

TSE R47 (Pro Co Rat pedal) - https://www.tseaudio.com/software/tseR47

TS999 and TSB-1- http://www.igniteamps.com/en/audio-plug-ins
(You can check out the other free stuff, such as the Emissary amp and NadIR, which I think is more stable than Lecab2)


Anyway, are you getting into recording or are you just jamming?

thanks so much, I'll look into that in details !!
I'm definitely getting into recording and Garageband is annoying me, that's why I'll turn to Logic (maybe Reaper) pretty soon.
