Hi,
it's been years and years and years
and I still don't know what settings
to put in my guitar effect box (will
be guitarix from now on I think, that
kicks and the little laptop here is
fast enough) to get a sound close to that:
http://sed.free.fr/example.mp3
The only word that comes to me when I
hear this kind of sound is 'toy,' and
it's not an insult. I love that little
toy sound. But I really don't know how
to reach it. I guess it's a lot about
EQ settings. Maybe the distortion has
to be special or I don't know... Maybe
you need a special amplifier of a given
brand and model...
Any idea anyone? anyone using guitarix
(gx_head) and able to reproduce the sound
and tell me what settings they use?
Thanks,
Cédric.

Hi Cédric
Presumably you mean the lead guitar rather than the rhythm? I can't say
that I see your toy association for the sound, but that doesn't really
matter.
I'm not sure I'm going to be of much help, but you're never going to get
exactly there even if you have all the same gear, because so much is
down to the individual player and their fingers.
But that said, you've omitted a crucial bit of information -- what type
of guitar are you using? I'd be very surprised if you'd get near that
sound with a Strat or similar, I would have thought you'd need something
with a denser body, although the Red Special is semi-hollow. I know it
has single coils, but to me it sounds thicker (whilst still being
trebly) than I've ever managed out of my Strat.
I'd guess treble pickup on a Les Paul type, you might get away with both
pickups on something with P90s (or treble and mid if it has three). If I
were trying to do something like that, I'd be tempted to reach for my
Yamaha semi with triple P90s, but it does tend to break up at high gain,
so the Les Paul might be better.
Apparently May likes the sound of an AC30 cranked right up so you'd need
an appropriate emulation and there is no substitute for volume when
doing a solo like that. I'd say you don't want too much distortion --
plenty of gain, but not much drive -- and probably a fair amount of
compression going into the amp. (I do wonder though just how close it's
possible to get with modelling software rather than hardware.)
Other than that, there really doesn't sound to be anything much going on
effects wise. I suppose something like a Tube Screamer might help a bit,
but I've no personal experience with those.
I've just found this video on YouTube, which might help a bit. So, I
stand corrected, pickups 1 and 2 on a SSS guitar and a bit of phaser:
http://www.youtube.com/watch?v=QmbTA9CAr30&feature=related
I still think you'd get close with a bridge humbucker on a heavier axe.
I'm sure someone who actually knows what they're talking about and can
help will be along before too long ;-)

okay, I'll dig in that direction.
I usually put input gain to max, drive to max, bass&treble to max
and medium to min. I don't know how to use a compressor, so I don't.
I get a nice sound for extreme metal stuff, but for those solos it
does not seem to work. Something does not fit, too much treble when
I attack the string I would say but I don't know...
Maybe I just should put an example of raw input sound for people
to play with it.
the sound is different, no? Is it just my ears (I mean brain)?

extreme metal band, so the settings that work well for that are not
likely to work well for Queen, so fiddle with the settings. For a start,
I don't think scooping out the mids is going to help at all, especially
with those gain settings.
I'm into prog rock/classic rock sort of style of playing and I have my
Marshall set with the mids to max (10, not 11!), treble at about 8 and
bass at about 6. My compressor pedals have tone controls and I often
turn the treble up a bit on those as well, when they are in use.
I've spent countless hours trying to get my three-channel amp set up to
my liking. For a metal sound (not something I do often) I might turn
both the channel drive and level up quite high, but for other styles you
don't need that amount of distortion -- it's a balancing act between the
drive and volume for each channel, plus also the master volume.
I don't actually use Guitarix or GX_head, but having found a screen
shot, it has the same three controls. You can have high gain, low volume
and have the master volume high to drive the power amp (assuming the
models are this intricately modelled), or low gain/high volume and
master volume to taste -- as I say, it's a question of getting the right
balance.
I used to crank the amp up to get those searing lead sounds, but they
always ended up too distorted, until I discovered stompbox compressors
-- instead of using (distorted) gain for the sustain, use a compressor.
Stompbox (pedal) comps are usually really simple to use -- for a solo,
turn the attack right down and the sustain level right up :-)
Also, are you using an appropriate amp model? For May, you want a Vox
AC30. I don't know anything about amps and tubes, but I don't think
GX_head has the right models for the AC30's valves.

The 6V6 emulation will come closest from all to the needed 6BQ5
When you use the version from SVN, there is a new extra clean tube mode
(without biquad filter) for the 6V6 and a 6V6 based postamp.
Also you will find a new 3Band EQ witch include a "sharper" based on a
compressor algo, if you have no experience with compressors, this one
will come handy for you.
Also new in SVN is that you can switch tube drive between distortion and
simple drive, and that drive/distortion slips to bypass when you set it
to zero.
And it's translated in French (by jy) thanks jy.

Okay, I tried a bit. I'm lost I guess.
I recorded: http://sed.free.fr/clear.wav.bz2
a short quick stuff, more or less in 7 times, turkish style :-).
(except at the end)
I tried to have separate notes with strong and clear attack
on each, as a start, kind of jazzy sound (I would say)
I used the two single pickups, I think that's what the
guitarist from Queen did (there was something about
phase, no?). Anyway, I can record with other pickups.
If someone has some time to play with this sample in guitarx...
(I have gx_head 0.13.0)
or to tell me that it's not the correct pickups in use.
Ah, and there is also this button on the guitar. Looking
inside the body, there is a "condensateur" (french word)
attached to it, I guess it's kind of a low-pass filter?
I turned it up (so sound with treble I think). Well, it's
an "open" sound, that's how it feels. (Hum, wait, I don't
remember if I did it open or close...)
Well, I can record different stuff too, if this one is too hard
to use (because when you dig for a sound you play this or
that sort of notes maybe).
About compressor, there is: knee, ratio, threshold, attack
and release. I understand threshold, attack and release.
What is knee? and ratio?

Reading a bit more, May's guitar has "phase switches" to change the way
in which the pickups are wired in relation to each other. Not something
you can do quickly or without a soldering iron on most guitars.
Well, I installed GX_Head. Give me hardware any day, although sadly my
amp is off being repaired, not that it would have helped in this instance.
I've fiddled around for several hours, including sort of learning the
solo. Listen at your own risk and beware, extremely crappy playing
ahead! It's not even necessarily all the right notes, let alone in the
correct order. This is about the nearest I can be bothered getting, both
note wise and tonally. It's played on three different guitars with
different pickup configurations:

To cover that we have made some of the knobs bigger, that the ones you

A chorus, for example in mono, isn't what I wont, but you can also skip

a short quick stuff, more or less in 7 times, turkish style :-).
(except at the end)
I tried to have separate notes with strong and clear attack
on each, as a start, kind of jazzy sound (I would say)
I used the two single pickups, I think that's what the
guitarist from Queen did (there was something about
phase, no?). Anyway, I can record with other pickups.
If someone has some time to play with this sample in guitarx...
(I have gx_head 0.13.0)
or to tell me that it's not the correct pickups in use.
Ah, and there is also this button on the guitar. Looking
inside the body, there is a "condensateur" (french word)
attached to it, I guess it's kind of a low-pass filter?
I turned it up (so sound with treble I think). Well, it's
an "open" sound, that's how it feels. (Hum, wait, I don't
remember if I did it open or close...)
Well, I can record different stuff too, if this one is too hard
to use (because when you dig for a sound you play this or
that sort of notes maybe).
About compressor, there is: knee, ratio, threshold, attack
and release. I understand threshold, attack and release.
What is knee? and ratio?

When you use the version from SVN, there is a new extra clean tube
mode
(without biquad filter) for the 6V6 and a 6V6 based postamp.
Also you will find a new 3Band EQ witch include a "sharper" based on
a
compressor algo, if you have no experience with compressors, this one
will come handy for you.

ratio is the compression rate (level),
knee, when you set knee to zero you get hard compression, as higher
knee, as softer the compression, knee add a convex compression aria to
threshold. The compression kicks in gradually at threshold-knee and
reaches its full value at threshold.

And thanks for guitarix by the way. It's really an amazing
piece of software. Something like 10 years ago or more I
tried some stuff but miserably failed so I kept going with
this digitech RP3 my ex-guitarist gave me. (Un?)fortunately one of the
knobs is getting old so I tried guitarix. And when I kicked the
strings with guitarix running, man! that was a great moment
of my life! Not for my neighbors I guess, but hell, that was
something. There are issues, like jack refusing to work with
buffers of less than 512 frames (I am not with a rt kernel)
but I'll get around that. Did some people already made sorts
of "minijack?" like implementing a minimal jack lib so that
you can use jack programs without jack? Anyway, I'll make a
little stuff and see how it goes. So many projects and so
little time...
Thanks!

Hello Cedric, now you're using an onboard card that prefers 2 periods
per buffer together with an USB card that prefers 3 periods per buffer
so either of the cards is not configured optimally which could cause
xruns. I'm not an expert on this but I think you might achieve better
results with the alsa_in/alsa_out tools.

Obviously you're perfectly free to ignore the recommendations and

try the things suggested to you and see if things start working?
Since noone's asking you to remove anything and/or install new kernels
and other software you can always, easily, revert to the non-working
state you have now and live on (un?)happily.
The point in making educated guesses is to have people try them out
and see if things start working. If they refuse to do that, we won't
get anywhere.

Step one in bug hunting: limit the amount of error sources. If there's
a problem running something on 294 different sound cards, try running
with just one first and see if the problem disappears.
There's a possibility that Jack works fine in your multicard setup,
but until we find the exact problem you need to strip things down to
the bare minimum.
But if you dislike Jack that much, feel free to explore other ways of
playing and recording. I hear you can buy recording software for other
operating systems that work reasonably well.
Thanks for your suggestions.

More importantly, you can only use two sound cards with JACK at the
same time if their sample clocks are synchronized. This can be
achieved with an S/PDIF connection between the two cards, but of
course that's only an option if both cards actually have digital
connectors.
Without synchronization the sound cards' sample clocks will drift,
which invariably leads to xruns. This is not JACK's fault by the way,
it's simply how the hardware works.
The only other solution to this is resampling, which is what alsa_in
and alsa_out do. But resampling will have some negative effect on
audio quality, so I would only use it as a last resort. Why exactly
don't you want to use the USB device for both capture and playback?

Same thing... All JACK does is basically move audio samples between
sound cards and applications. What that means is that every device
involved must produce/consume samples at the same rate.
The only way to overcome this is resampling, but for good reasons JACK
won't do that unless you ask for it (by using alsa_in or alsa_out).

Jacks uses one system-sample-clock. And all sound-devices then have to use
that as well. Doesn't matter whether one device is only playback or only
recording. All hardware-sample-clocks have to be synchronized unless you want
to use alsa_in (or alsa_out) and have automatic resampling inserted into the
chain. And if you want good quality, you don't want resampling. At least you
don't want it added automatically without control...
