Spider IV Guitar Amplifier Overview | Line 6 [updated video
]



Over a million guitarists
have chosen Spider amps. With Line 6 reknowned
expertise in amp and effects modeling and dialed in rockstar tones,
Spider IV amplifiers deliver a truly evolved playing experience.
They'll surprise you with the way they respond to a player's touch
and the way the guitar jumps from the amp with a tube-like feel and distortion.
The amp really sings. On top of that, we've got over 500 presets
to get you started and some flat out wonderful new effects and features.
We had a blast getting some of our favorite players to dial in presets for Spider IV,
amazing players of all styles from Johnny Marr, Steve Stevens
and Lee Ritenour to bands like Hawthorne Heights, Slipknot
and Minus the Bear to studio giants like Tim Pierce, David Torn
and Pete Anderson. We'd bring amps to them or send amps out on the road to them
or we'd tackle them when they came by the offices. We managed to get over 300 presets
to inspire your playing.










We also included around
200 presets based on some of the greatest guitar songs of all time;
Master of Puppets, Back in Black, Whole Lotta Love, Purple Haze,
Crazy Train and lots lots more. There really is something in here for everyone
and it's yours at the touch of a button.








Spider IV 15 and 30
each have a perfectly distilled collection of "go to" amp tones
that guitarists absolutely depend on. Go from
sweet, sparkly cleans to molten lead tones along with
a palate of crucial effects all in a box that's small enough to stick under your
desk or bed. Don't let their little size fool you. These guys really rock
and along with their bigger brothers they also have a 3/4 closed back cab
that really moves air. Spider IV 75,
120, 150 and HD150 include
16 of the best sounding models we've ever put in an amplifier.
We've worked really hard across the board to up the ante with
some beautiful new cleans that sound and feel amazing, some
edge of crunch mid-gain tones that capture everything we love about
playing with an amplifier that's just on the edge of breaking up and some incredible
musical high gain tones that really blaze.









We've got some really exciting new features in Spider IV. One of
them is a built in looper called Quick Loop. It features 14 seconds
of looping time and can be operated from the front panel or
integrates perfectly with one of our FBV Shortboard or Express
pedals. If you've been a little scared of looping in the past, don't be afraid
of this one. It's really fun and it's really easy to use.











We have a couple of amazing new
pitch shifting effects in Spider IV, Smart Harmony
and Pitch Glide. Smart Harmony is an
intelligent pitch shifter. It lets you choose your key, your scale
and your interval. It let's you set your mix level. It tracks
amazingly well and it will have you soaring with dual guitar lines
in no time.





The Pitch Glide effect integrates perfectly with our FBV
Shortboard and Express MkII for some incredibly fun pitch effects.
We've even included a whole category of pitch presets
to get you started. Then once you're comfortable, you can go in and customize your
toolkit to add a whole new level of expressiveness to your playing. This thing is really fun.







Spider IV 75, 120, 150 and HD150
all come loaded with 20 great sounding Smart FX.
We've included such must have effects as Spring and Plate Reverb,
Digital and Tape Echo Delays, Chorus, Phaser
and Flange. We've also included some really fun stuff like Auto Wah,
Multi-Head and Reverse Delays, Compressor and Fuzz Pi.
These effects all sound great and it's easy to
dial in a great sounding effect using just one knob. But, we didn't
stop there. We wanted to give you the ability to completely customize
your sound. So every effect in Spider IV 75
and up is completely editable, giving you access
to up to 6 parameters per effects including the ability
to place the effect pre or post amp model. Our larger
display makes editing a breeze, giving your imagination
a terrific canvas to explore the possibilities. For total
control of your effects and your presets and to take full advantage of
all the power that's in a Spider IV, the FBV MkII
footcontrollers are a must. Using an FBV Shortboard MkII to
loop on the fly or to do a dramatic pitch glide is worth the price of admission,
but you'll come to depend on it to kick on the tuner, turn your effects
on and off or to run through your band's setlist with your own presets.
Available in 3 sizes to match all the Spider IVs,
the FBV series of footcontrollers are a perfect addition to your arsenal.
Spider IV is crafted to sound great. All of our painstaking
sound design gets loaded into a brand new 3/4 closed back cabinet
and then in most cases connected to a custom Celestion speaker that delivers
a tight low end and a punch that really cuts through the band.
When the band isn't around, plug your mp3 player into the 1/8" jack
and jam and practice to your own tunes. Use the direct
recording headphone out when the kids are asleep or when you wanna lay down some
guitar tracks direct, no mic needed. We are extremely proud
of the look, sound and feel of Spider IV amplifiers. Every one of them
is extremely versatile and an incredible value. Finding your
tone is easy with handmade artist and song presets and tons
of amazing effects, all from the industry leader and pioneers
of amp modeling, Line 6.




MP3GAin finding volume of your MP3 files


hello everybody in this little video i'm
going to describe a marvelous tool for determining
the actual volume of your MP3 files
before up loading them
welcome to another help video for LibriVox recorders
this is PC Phil Chenevert
with a video showing an easy way of determining
the volume level of your MP3 recordings
well that is if you're using windows
uh... it doesn't seem to work with mac
But this neat program called
p MP3 Gain
will tell you the volume level of your MP3
recordings and it will give you a recommendation
of the amount to increase or decrease
the volume to achieve the uh... desired eighty-nine
decibels
now the volume of
our recordings can vary greatly
this is a picture I took a three different
recordings I made
the top one is very puny and weak because
the waves are very small... they hover around
that middle line
one looks like it's way too high, in fact
they even have a lot of clipping right
here and here
and the last one looks like it we had normal
recording for me
well we'll check it out in a minure.
The volume that libriVox likes us to
have when we upload files is 89 decibels
or at least something
close to it let's say within four decibels
of that
anywhere from eighty six to ninety three is
acceptable I've been told
but even that isn't set in stone. eighty-nine
just gives us something to shoot at
so how do you do it: well I've recorded this particular
audio (an MP3)with audacity
and i'm going to drag it into the box,
We're going to cover this first:
first thing it tells me is that
our normal volume is 89.3
three this can be changed
it tells me the volume, right here
.. the volume is 71.7
and it tells me it's recommended a track gain of 18.1. do not
use Track Gain. This will automatically
adjust certain things inside of your recording
we don't
want to use that
Rather, to adjust this thing we're going to open up
that file in whatever editing program you
you
I use
audacity
now this is my little anemic file apparently
I will select the whole file go to
:02:36.519,0:02:38.089
Effect
then amplify
and it asks me how much to amplify
Now when you open up Audcaity, the Amplify dialog box will
will tell you the absolute
maximum that you can amplify
without clipping
Now in this case it is 18.2 ..I'm just
gonna change that two 18.1
and this means it's going to come within
one tenthth of a decibel
of clipping but it won't actually clip
click ok
now you may be able to see that this file
is much bigger
now if you were doing this for LibraVox
or if i was doing and i would export it
one more time
using the exact same file name that i used
before
which is whatever it is "low volume one"
save it in the same place
clear
the thing an see if i can drag it in here
and do it if i can't ..well it's gonna give me problems
OK, Analyze it ..AH!
i have now
increased the level to 89.3 which is
very close and very acceptable
so at that point i could
export this or upload it to LibriVox and
it would be fine
(humming)
OK, let's clear this and load another one: I call
call this
normal volume
eighty nine point one that's pretty darn close
in this case
i wouldn't do anything to it but upload
the file The next one I called "high volume"
becuse
it's kinda high volume
MP3Gain analyzes it and tells me it's 95.7decibels
let's see if i can amplify that again
95.7
(this is a little tool i think clled "magnifying
glass")
It is recommending a negative -6.0
that means it's necessary to go back and
reduce it, so that's what we're going to do
so i will open up this file in
audacity
selected it. Once again go to Effect>
amplify
and i'm gonna type in
-6
and let's see what it's going to happen here
well that certainly did reduce it that's
a nice pretty file now. Once again i'll do
the same thing i will
exported using the same name that i used before
because it's been modified
and let's see if it gets me to... track analysis
89.2
89.2
So what it recommends
will come pretty close. Now Track Gain or
negative is only in steps of one point five
decibels
however you don't have to use what they are recommending
if you're uh... volume here is showing 80
and they have something else you can you can
simply increase it by 9
and you'll come up to 89. you can
use your own estimation on these things
now these are pretty normal files but what
happens if you have clipping
or peaks?
let's see if this one works here
one of the problems with these files
with some files is that they have clipping
now clipping
is when your volume is so loud that it
exceeds the uh... the program's capability
to record it and so you lose
the bits at the top or at the bottom
you will notic that this particular farm has...
yes clipping
and the whole track has clipping in it
So MP3Gain is recommending to gain 4.5

this is the actual file
and you can see that some of my waveforms
here go
go pretty high
i'm just zooming in, that's
all
so we can see and this one here is the one
that's
that's clipping
and uh... an interesting point or aside
is, if you have trouble with a lot of clipping
you can go to View
and there is a little thing here "Show Clipping" clipping
This means as your are recording and
you have a clip, it will pop up in red
you can immediately stop and re-record that
but let's assume that you don't normally have
trouble
(shrink this back down)
if we try to amplify this file it would
not allow us to amplify it
see, it says zero, zero. you can't amplify
this file at all
So, how can we do this? well this is how i do it
i would zoom in on that particular file there
wherever it is ... here it is right here
highlight it and
uh... negative amplify it ...let's say a -4 negative four
That shrinks it right on down them
now if i may have lost may have
lost a little bit of the peaks up there
here's another one that we want to de-amplify
i'm going to zoom in going to
zoom in; and
choose that go to effect amplify and negative
uh...-3
I'm just choosing these numbers because that's about
what i would look for
next I will look at the entire file by clicking
up here
Whoops! I still have one right here
tricky tricky Phil
tricky tricky
Effect > amplify
negative
-4 (I like -4)
once again I'll go here so I can put my entire
uh... track into one thing i can see ... that's
pretty good
now let's see how much i can amplify it
i can amplify by four
and i think they recommended four so let's
try it
i still have these clicks but we'll see
see what happens here
i'm going to
export it
as "peaks" same file name
Clear it and let's see if I drop "peaks" in here what it will dowill
do track analysis
88.1 ! one
now it shows that I would still have
a clip
it says that if you amplify by 1.5 i would still havbe clip, well I don't
want to amplify any more and that is justfine with me
and if you wanna know what decibels are
well, you can ask somebody else because i'm not sure
i do know that the format used in in MP3Gain
is SPF or something it means
how does a human ear hear the sound how
loud does that sound to the human ear
uh... so it's sort of a different formula
but
it works very well
disclaimer remember this is all my opinion
and may or may not represent the views of
those people who actually know what they're
doing
uh... warranty is void if used while emersed in buttermilk

thank you very much
