A. INPUT — Plug your passive or active bass in here. If your
bass is too hot and causes distortion, try using the -6dB
switch.
B. -6 dB — Press this switch IN to provide additional
headroom for hotter basses.
C. VOLUME — Controls the loudness of the amplifier.
D. GAIN — Controls the amount of OVERDRIVE distortion.
F. BLEND — Controls the amount of distorted signal (set
by GAIN) to be blended with the clean bass signal.
Lower settings can maintain a cleaner tone, with some
added grit. Higher settings will produce more distorted
tones and add sustain.
E. ENABLE — Press this button to turn the OVERDRIVE
on or off. The red LED (light) illuminates when the
OVERDRIVE is on.
G. SHAPE FILTERS:
• PUNCH — Emphasizes tight punchy bass response,
useful for finger style playing or for enhancing the tonal
character of a bridge pickup.
• SCOOP — Mid-frequency cut, combined with low-and-
high-frequency boosts that offer a fat pleasing tone,
useful for slap style playing, low-volume practice, or in
combination with OVERDRIVE.
H. 4-BAND EQUALIZATION (RUMBLE 150 ONLY)— Used
to adjust overall tone and to compensate for room
acoustics. Remember, what sounds harsh in one room
may have just the right edge in another room.

I. 3-BAND EQUALIZATION WITH SEMI-PARAMETRIC
MIDRANGE (RUMBLE 350 ONLY) — Having more
control over the midrange frequencies is very important
in defining your bass tone. The Rumble 350 is equipped
with a semi-parametric midrange with FREQUENCY
and LEVEL controls that work together to allow greater
flexibility to adjust a specific range of frequencies (tones).
Use the FREQUENCY knob to select which frequencies
you would like to adjust, and use LEVEL to control how
much to boost or cut at these frequencies. Boosting
upper-mids (FREQUENCY near 1.5kHz) and favoring the
bridge pickup on your instrument creates a biting tone
that is great for Jazz Fusion type melodic lines. Cutting
mids (FREQUENCY near 700Hz) is useful for funk or slap-
style playing.
TIP: It is easiest to adjust the MIDRANGE when the LEVEL
control is at its maximum or minimum, so that the effect
of the FREQUENCY knob is more easily heard. Once the
proper FREQUENCY setting is found, adjust the LEVEL
knob to the desired setting.
J. FX LOOP — Connect the SEND to the input of outboard
effects devices (delay, chorus, etc.) and the output of the
effects devices to the RETURN. Placing effects in the
FX LOOP (instead of between your bass and the INPUT)
will reduce the amount of noise and tone degradation
caused by the effects pedals.
TIP: You can connect the SEND jack to other devices
(such as tuners, or additional power amplifiers) without
connecting signal back to the RETURN jack. Returning
signal to the RETURN jack is not required for operation
of the amplifier. Additionally, you can connect external
signals to the RETURN jack to bypass the preamp controls,
and send external signal directly to the power amplifier.
