To keep yo
u
r signal clea
n with an active bass instrumen
t, boost your freq
u
ency
from on
e sid
e o
nly. For examp
le, if you raise the ba
ss on yo
ur in
strument, leave
the b
ass on your amp
‘flat’, o
r vice
versa
. An active
bass a
lread

as a p

inside. Tha
t mea
ns you are going from the preamp in
yo
ur b
a
ss to a

o

amp
in
your amplifie
r head
. By boosting
the bass in
both
p
reamps, you’ll cause
distortion from overload

A
200-watt
amp
does not
sound twice as loud as a 100 watt amp). If you need
more volume, start by adding more cabinets.
Bass frequencies are hard to amplify and are demanding on loudspeakers. To
compete with a 100-watt guitar stack, you should use a PS head with two PS
cabinets.
