1.) Guitar Input - this is a 1/4 2 conductor input jack for plugging in your instrument. It is intended for
bass guitar or Hi-Z microphones but will accept other instruments as well.
2) Volume Level - this control is the output volume control for the bass guitar input. Slowly increase
the control to increase the volume. If you are using a bass guitar with an on-board preamp, set its level
for a mid position before increasing this control otherwise distortion may occur.
3) Low - this control is the bass control. It is passive and set to shelve frequencies at 100 Hz. This
will effect the low frequency signals. Turning it fully clockwise, the signal is basically left alone. Turning
it counterclockwise, the low will be rolled off -12db. Especially good for making low output, thin toned
bass guitars sound fuller.
4) Mid - this control is the Low Midrange control. It is passive and set to shelve frequencies at 500
Hz. This will effect the mid-low frequency signals. Turning it fully clockwise, the signal is left alone.
Turning it counterclockwise, the mids will be rolled off -12db. Especially good for cleaning up muddy
bass guitar overtones.
5) High - this is the high frequency control. It is passive and set to shelve frequencies at 3KHz. This
will effect the high frequency signals. Turning it fully clockwise, the signal is left alone. Turning it
counterclockwise, the highs will be rolled off -12db. This will add or subtract the high end attack of
slapping style sounds or pick attack and clarity.
) Headphone Jack - this is a 1/4 3 conductor jack for plugging headphones. It will sum the signal
and put the sound in both ears, thereby creating a pseudo-stereo sound. Volume will be determined
by the volume control on the channel you are on. It will disconnect the internal speaker when plugged
in. This will allow quiet practicing.
7) Power - this switch turns on and off the AC power to the amp.
8.) Power LED Light - this LED light lets you know that the amplifier is on.

Suggested Settings
(These settings are general starting points. They
are designed to get you close to the sound you are
looking for. If the control is not shown, then it doesnt
apply to this particular sound. )
Traditional Electric Bass Setting - in this setting the amplifier will deliver a standard
electric bass sound. Whether you are playing rock, country, blues or gospel, this setting
will get you close. Because of the wide range EQ, you will be able to dial in your preferences
from here. If you play with a pick and want less top end attack on the notes, roll off a bit
of the High control. If its deeper bottom your looking for, add more low and low mid. The
key is to experiment to achieve your own personal sound.
Funk Slap Sounds - this style of music needs a good strong attack sound with lots
of top end. Usually a hollowed out middle will produce the extra top end necessary for
the punch needed for this style of music. If you are using a more thumb style, a bit more
low end and volume might be needed for your particular style of playing. Or less if you
really hit it hard. Even though this is a practice or rehearsal level amplifier, it will deliver
the punch and clarity that you require.
Alternative Style - this setting is designed for a upper end punch and edge that will cut
through most any sound. This style will work well with pick or fingers and will add a touch
of distortion to the sound as well. Make sure your instruments volume control is up all
the way. Since you are adding volume, you need to be careful with the actual amount
of e.q.. you use as it also can add distortion to the sound. Also, you may want to use a
compressor pedal in the signal chain before the amp to give it a smoother sound but still
edgy. As in all the settings above, it is strictly a matter of personal taste in a achieving
the sound you are looking for.....experiment.
