2.GENERAL INFORMATION
Basstodon is a bass guitar head amplifier. Being highly versatile and very
functional, Basstodon is able to work with cabinets of almost any wattage and
impedance, therefore letting the bass player obtain own unique tone depending on
playing style, musical material, either being in a studio or playing live as well. On
the front panel you can see the following control knobs: VOLUME, GAIN, BASS,
TREBLE, and also a parametric mid-range control – MID LO, MID HI and FREQ. If
a bass guitar is equipped with high-output pickups, there's a switchable pad of
-15 dB to avoid input overload, indicated by CLIP LED blinking.
On the rear panel you can find a TUNER OUT, an effect loop (SEND and
RETURN), balanced DI-OUT that can be adjusted with LEVEL DI-OUT control, a
preamp output marked as LINE OUT and SPEAKON connectors to run the amp
with 8 or 4 Ohm impedance cabinets.
DUAL/BRIDGE mode makes it possible to connect a single 8 Ohm or two 4 Ohm
cabinets to the amplifier.
Attention! It's prohibited to use additional cabinets while running the
amplifier using an 8 Ohm output.
While using two 4 Ohm cabinets connected to relevant outs , the amplifier runs
the DUAL mode. While using a single 8 Ohm cabinet, the amplifier runs the
BRIDGE mode. Wattage switch (50, 100, 200, 300, 400 Watt for DUAL mode or
100, 200, 400, 600, 800 Watt for BRIDGE mode) lets the player choose a suitable
mode to run the amplifier with cabinets of any wattage.

Connect the amplifier to an 8 or 4 Ohm impedance cabinet.
Running cabinets with 8 and 4 Ohm outputs simultaneously is strictly
prohibited!
Please be sure that the amplifier's output wattage does not exceed the
cabinet wattage in order not to damage the cabinet!!!
Adjust the maximum output wattage using the dedicated switch in accordance to
the cabinets' wattage. Plug the supplied power cable to the main power input, then
plug it to an earthed electric socket.
Plug the instrument cable to the input jack on the front panel.
Turn on the POWER switch. Power on will be LED-indicated.
The amplifier is ready to use.
Using the GAIN control adjust the preamp until the CLIP indicator starts blinking
when playing loudest notes. Adjust the tone of the amplifier and the output volume
as desired.
To power off the amplifier turn the POWER switch down.
