Guitar
Effects - Order & Tips
Probably the main thing to understand
about effects order is that an effect modifies the sound it receives. This
means if you plug your guitar into a fuzz box, the fuzz box gives you a fuzzy
guitar sound - pretty obvious, huh? If you then plug the fuzz output into a
wah pedal input, then the wah works on the fuzz sound, giving you a synth-like
wah sound.
If you plug first into the wah, then into
the fuzz, it gives a completely different sound. That's because the fuzz is
working on a guitar sound that already has a wah effect. You may know that
distortion effects like fuzz have more effect on loud sounds than quiet ones
(that's why they sound cleaner when you roll off the guitar volume). And a wah
pedal makes different notes and frequencies louder and softer as you rock the
pedal, so rocking the pedal also now controls the amount of fuzz as well, giving
what most players prefer as a more interesting effect.
There are no rules on effects order. You
won't break any pedals by putting them in a 'wrong' order. In fact,
experimenting is the best way to learn, and in doing so, you can come up with
many unusual and interesting sounds. There is, however, a typical order of
effects that I've listed below.
Before we get into the order, though, you
might like to consider why, when & how you use effects. My most deep piece of
wisdom to pass on is that the subtle use of effects is suitable for long periods
of use, while intense effects have most impact when used briefly.
For example, light phasing or chorus can
be used for an entire song, adding some texture to backing rhythm. Dramatic
effects like strong delay, wah, or even playing techniques such as continuous
fast picking without a rest, become tiresome when overused.
I think the most special effects are those
that you can only just detect are turned on. In the late 70's, I had many
people trying to figure out how I got a such a special overdrive sound for my
solos. All I did was to use a faulty (weak-sounding) phaser set to a slow
speed before the overdrive, to give just a hint of movement. You can use
understated effects easily to craft your own signature sounds.
Typical
Order
A good starting order, from guitar to
amplifier, is:
Filter effects
These effects sweep a peak (wah) or notches (phaser)
in the frequency response. By placing these before distortion effects, they
vary the distortion intensity of the affected frequencies at the same time.
The original Vox and Cry-Baby wah pedals
did not use a true bypass when off, and can load your guitar signal. If this
is a problem for you, you might want to have the switch replaced with a true
bypass.
Another way around the problem is to use a
"buffer preamp" before the wah, which can be any effect with electronic
switching, turned off. If you use a phaser as well, plug that in first, and it
will happily drive the wah pedal.
Compressor
Even though many players suggest compression
should be first, there is benefit in placing it after filter effects. Filter
effects can reduce volume at some settings (eg heel down on the wah pedal,
notches in the middle frequencies from a phaser, etc), so placing a compressor
after these effects can even out volume changes.
Overdrive/Distortion
- Stomp-box effects
- or your pre-amplifier drive channels
Placing overdrive after the filters gives
them a more natural sound, like placing your wah pedal before a heavily
overdriven amplifier. Using the filter effects after overdrive gives them a
much stronger, more synth-like sound.
You would not normally need to use heavy
compression and heavy overdrive together.
There can be merit in using light EQ
before the overdrives (used only when the overdrive is on); this gives you the
ability to change the character of overdrive. For example, boosting the highs
before overdrive, but cutting highs after overdrive (with the overdrive's tone
control), will balance the highs overall, but cause them to be more heavily
overdriven than the lower strings.
The overdrive could be the preamplifier in
you amp. You can use this if your amplifier has an effects send and return, to
allow you to use the remaining effects below. You may need to check the levels
sent and expected by the send/return loop; often they are designed for line
level only (eg rack equipment) and not the lower level stomp boxes.
Some send/return loops allow you to blend
the return in an equal mix with the unaffected signal. This is great for not
affecting your original signal, which can become quite unnatural if taken from
the amp, processed by one or more analog-to-digital-to-analog conversions, then
re-input. This increases the complexity though, when you want to remix chorus,
flange, delay and reverb, all without any original component. Also, you may
want some of these effects to be fed with inputs of a mix of original and other
effects. These capabilities are often not provided in rack products.
Equalisers
- Graphic
- Parametric
- Speaker Simulators
These effects can be used on their own, to
tailor solo or rhythm sounds, or with overdrives to give more control than you
usually have with the overdrive tone control. For example, you could use heavy
distortion, and use equalisation here to cut middle for a heavy sound, or tailor
the highs for a creamy, yet "bitey" Santana sound, etc.
Before using a volume pedal to control my
on-stage volume, I used a graphic equaliser stompbox to set a nice rhythm tone,
with reduced level. I set my amp for the lead sound I wanted, and (although it
sounds strange) turn the equaliser OFF to play a solo.
Speaker simulators are mostly preset, and
highly tailored equalisers to emulate speaker box resonances, and microphone
techniques. Some include other subtle effects, such as short delays, as well.
Placement is not as crucial as you might think. For example, most recorded
sounds use a microphone in front of a speaker box, then studio effects, such as
equalisation, chorus, delay, etc applied afterwards.
On the other hand, when you play live, and
are using a variety of effects through a stage power amp and speaker box, you
might want to use the simulator here only for the purpose of feeding the mixing
desk (who apply their own delay and reverb for the front mix). You could
bypass the simulator on stage, and apply just enough delay/reverb to give a
natural on-stage sound.
Pitch Effects
- Harmoniser
- Vibrato
- Pitch benders
Harmonisers in particular should be placed
after overdrive. In the opposite order, sending several notes to the overdrive
input causes strong inter-modulation distortion where additional, usually low,
notes are added. These extra notes may have no relationship to the harmony you
intend.
Modulation effects
These are effectively combined filter, delay
and pitch effects. Because each of these effects is subtle (unless you set
high resonance), many players prefer them after distortion, and prior to echo
effects.
Level controllers
- Noise gate
- Limiter
- Volume pedal
- Tremolo
- Panning
Placing level effects before echo effects
allows a natural echo sound. For example if you play a loud chord, but fade it
out quickly with a volume pedal, you still want to hear the echo on what you
played. The other way round, with echo first then a volume pedal, you would
hear a loud chord with echo briefly, with both the main souund and the echo
quickly cut out to silence. This sounds about as natural as turning the power
off on your amp!
Echo Effects
These effects are usually placed last to allow you to emulate the effect of
using an amplifier in a "lively" room.
