Rocket Bass Combo Series
RB-108, RB-110, RB-112, RB-115, or RB-210 Amplifier, Power Cable, Quick Start Guide.
Introduction
Designed from the ground up, with Ampeg’s industry standard tone and styling in mind, the all-new
Rocket Bass combos feature the legacy Ampeg preamp and tone stack circuits with the widest
range of classic Ampeg tones any Ampeg combo has ever offered. The new SGT™ (Super Grit
Technology) overdrive circuit gives you the warmth and grit of a monster SVT® stack, packed into a
lightweight combo that you can easily carry to any practice or performance.
Iconic black diamond vinyl, reminiscent of the most recorded bass amp of all time, the Ampeg B15,
wraps the most lightweight cabinets Ampeg has ever built, without sacrificing ground shaking lows
and classic Ampeg tone. Integrated DIs, effect loops, and aux in/phones out circuits provide the
ultimate tools for any rehearsal or gigging situation.
Like all Ampeg products, your Rocket Bass combo is designed by musicians and built using only
the best of components. Each combo is tested to confirm that it meets our specifications, and we
believe that each amp is the best that it can be.
In order to get the most out of your new combo, please fully read this Owner’s Manual, as well as
the Important Safety Instructions included with your Rocket Bass series amp, before you begin
playing.
Best of luck in all of your musical endeavors!
- And THANK YOU for choosing Ampeg! -

1. –15 dB INPUT: The attenuation of this 1/4”
input is suited for use with basses that have
active electronics or high-output pickups.
Connect here using a shielded instrument
cable.
2. 0 dB INPUT: The signal output from a
passive instrument may be connected to this
1/4” input. Connect here using a shielded
instrument cable.
3.
SGT
LED: This LED illuminates amber when
the SGT overdrive circuit is on.
4.
SGT
ON/OFF: Engage this switch to activate
the SGT overdrive circuit. This allows
for varying amounts of tube-like grit and
distortion.
5. GRIT: Use to adjust the amount of SGT
"grit." Turn the knob clockwise for a more
overdriven sound (RB-110, RB-112, RB-115,
RB-210).
6. LEVEL: Use to control the overall level of
the SGT overdrive circuit. Turn the knob
clockwise to increase the SGT level. (RB-110,
RB-112, RB-115, RB-210).
7. VOLUME: Use to control the amplifier's
overall output level. It affects the preamp
level fed to the Speaker and Phones outputs.
Use it wisely and turn down when making
connections, wearing headphones, or when
trying something new. This control does not
affect any signal coming into to the Aux Input
(14).
8. ULTRA HI: This switch, when engaged,
enhances the amount of high frequency
output with 5 dB boost at 8 kHz (RB-112,
RB-115, RB-210).
9. ULTRA LO: This switch, when engaged,
enhances the amount of low-end output with
a 1 dB boost at 40 Hz, and a 10 dB cut at
500 Hz (RB-112, RB-115, RB-210).
10. BASS: Use to adjust the low frequency level
of the amplifier. The low frequency output is
flat at the center, "0" knob position. Rotate
the control counter clockwise from 0 to
reduce the bass frequencies—or clockwise
from 0 to increase the bass frequencies.
See the following pages for Technical
Specifications.
11. MIDRANGE: Use to adjust the midrange
frequency level of the amplifier. The midrange
frequency level is flat at the center "0" knob
position. Rotate the control counter clockwise
for a "contoured" sound (more distant, less
midrange output), or clockwise for a sound
that really cuts through (increased midrange).
See the following pages for Technical
Specifications.
12. TREBLE: Use to adjust the high frequency
level of the amplifier. The high frequency level
is flat at the center "0" knob position. Rotate
the control counter clockwise from 0 to
reduce the treble frequencies—or clockwise
from 0 to increase the treble frequencies.
See the following pages for Technical
Specifications.
