Front Panel Callouts
1. INPUT -
Connect your active or passive bass guitar here using a standard 1/4” instrument
cable. Our circuit is specially designed to accept signal from any bass instrument including
dual 9 volt active preamps.
2. DRIVE Knob -
Adjusts the amount of overdrive applied to the input signal. LX8500 footswitch
can turn this on (lit white) and off.
3. MUTE Switch -
When engaged this red backlit switch mutes signal to all outputs.
4. COMPRESSOR Knob -
Determines the amount of compression by adjusting the threshold level.
The compressor allows you to control the overall dynamic range of your performance by reduc-
ing sudden peaks, and increasing the sustain of the instrument. At the fully counterclockwise
position no compression is applied. As the knob is turned clockwise an increasing amount of
compression is applied. When the COMPRESSOR is engaged the lights around the knob flash
red providing a visual representation of the compression circuit’s status.
5. GAIN Knob -
Adjusts the amount of level provided to the tube preamp stage as well as the
TUNER output, DI output, and EFX loop. Set this control first to optimize levels for your style
and particular bass instrument then use the MASTER (#11 below) to adjust the overall stage
volume. The lights around the knob will flash red during signal peaks.
6. BRITE Switch -
Turns on the BRITE circuit which adds a preset EQ curve to enhance the
bass instrument’s high frequency response. This backlit switch will light red when engaged.
LX8500’s footswitch option can turn this feature on (lit red) and off (not lit).
7. BASS Knob -

response (80 Hz).

high frequency response (6 kHz).

on the position of the rear panel push button.
