Congratulations on your purchase of the Peavey Classic
the sound of the vintage amplifiers but with the features and reliability of modern amplifiers. Features such
as remote channel switching, remote switchable effects loop, and our patented DDT circuitry make for an
awesome professional bass rig. Modern distortion sounds are easily obtained in the Crunch channel, some-
thing that most bass rigs don't have! In fact, the Classic 400 is capable of mixing a screaming distortion
sound (from the Crunch channel) with the smooth tube sound of the Clean channel! So read on and familiar-
ize yourself with all the controls of the Classic 400 so you don't miss any of the great sounds you can
get—and be prepared to get blown away!
FRONT PANEL FUNCTIONS
INPUT PAD SWITCH (1)
Provided for instruments that have extremely high output, which can result in overdriving (distorting) the
input stage. Depressing the switch to its "in" position reduces the level of the input signal by 10 dB.
INPUT JACK (2)
This input will accept signals from all types of bass pickups.
CHANNEL SELECT SWITCH (3)
Allows selection of the Clean or Crunch channel. The "out" position of the switch selects the Clean channel,
and the "in" position selects the Crunch channel.
