Contact Point Cleaning – 

One of the weakest links in most bass

amplification systems are the solderless connection points where
instruments, speaker cabinets, effects, and other devices are connected to the
amplifier. (The most vulnerable of these types of connection is the jack on
your instrument). In addition to contamination from airborne pollutants,
these points are frequently assaulted by connectors that have picked up
debris from dirty stages, cases, etc.

This contamination can result in poor contact as well as poor tone, and we
all know that bad tone is a 

Very Bad Thing

. These points should be cleaned

regularly with a cotton swab soaked in denatured alcohol or a commercially
available de-oxidant. Frequent cleaning of the plugs on your cords is also
recommended.

Dust Removal – 

You should periodically inspect the ventilation openings

on the front and back of the unit to ensure that they have not become
blocked by accumulated dust. Vacuum the openings to remove any dust
buildup. Dust bunnies are definitely not cool.

The Magic Smoke 

– Few people realize just how much magic goes into

creating Great Bass Tone. It isn’t something you normally need worry about.
Just have fun and leave all that to us. However – 

and this is very important

 –

if you ever release the Magic Smoke from your amplifier this is indeed a

Very Bad Thing

, perhaps the worst thing you can do. If you see any smoke

(Magic or otherwise) coming out of your amplifier, immediately turn it off
and seek the services of a qualified magician…uhm, we mean…technician.

DO NOT continue to use the amplifier in this condition

.
