Remember the famous
guitar amp in Spinal Tap -- the one that sounds
awesome, 'cause it goes all the way up to eleven?
Sure, it's a joke, but there's a lot of people out
there who are definitely of the opinion that
"louder is better." A generation of hard
rock bands have done little to dispel this myth --
the "solid wall of Marshalls" is a staple
of stadium rock.
Well, here's a little eye-opener for you. The dozens
of Marshall cabinets you see on the stage for a Kiss
show are mostly dummies. Lead guitarist Ace Frehley
actually just plays through a single Marshall stack
to get his sound -- one of the cabinets in the stack
is then miked, the signal goes through the PA, and
it's the PA that provides the main part of the volume
-- not the amps on stage. Of course, if you're not a
stadium-size rocker, even the sonic muscle of a
single big amplifier can be overkill. A smaller
amplifier often gets better tone than its big
brothers, so a small combo amp may be the best way
for most live shows.
Here's why: if you're using a large amp in small
venue, you won't be able to drive it hard, which is
what is required to get a decent tone. Master volume
amps provide distortion at lower volumes -- but
that's no substitute for the sound of actual power
amp distortion. A smaller amp actually allows you to
get more real amp tone, since you can turn it up
higher.
There's more. Place a mic in front of the speaker and
run the signal through the house PA, and you have the
volume you need as well as the tone. The house sound
guy can now get the best possible sound through the
PA without excessive bleed from your amp. The more
amp noise on stage, the harder that is to achieve.
Plus with a lower on-stage volume, you can get just
the right amount of your own amp sound fed back
through the stage monitors, along with the other
instruments, to give you the ideal stage mix.
High-quality small amp offerings from the likes of
Fender and other major amp companies show that the
hard rock "wall of sound" movement is
losing its grip. Get with the times, and think about
trading the 100-watt monster for a smaller model --
your bandmates (and roadies) will appreciate you for
it.
Tip:
Many modern amps are designed for stage power levels.
When required for studio or home use, their
background noise and power may be a nuisance. A short
patch lead with a 50k resistor in series with the
inner conductor attenuates the amplifier to a more
suitable level when connected to the effects send
& return sockets.
