1. 0dB Input accepts a standard
1/4” instrument plug from your bass.
This input is suited for use with
instruments that have passive electronics.
2. -15dB Input accepts a standard
1/4” instrument plug from high output basses. This input is padded
15dB to compensate for higher output sources and is suited for use
with basses that have active electronics or high output pickups.
3. Ultra Low increases the low frequency output by 7dB at 40Hz. This
adds to the rumble and overall feel
of the low bass notes.
4. Ultra Mid decreases the mid frequency output by 6dB at 600Hz.
This removes some of the middle
frequencies for a “contoured”
sound.
5. Ultra High increases the high frequency output by 7dB at 5kHz. This
adds crispness to your sound.
6. Peak LED will illuminate when
the Gain control (#8) is set too high.
This indicates overdriving of the
preamplifier which causes clipping.
(See the Gain control, #8.)
7. Signal LED will illuminate when
the Gain control (#8) is adjusted
properly. (See the text for the Gain
control.)
8. Gain must be adjusted to match
the output of your instrument to the
amplifier. For the proper setting,
turn on the amplifier, turn the Gain
control and the Master control (#13)
all the way down and begin playing
your bass. Turn the Gain control up
until the Signal LED (#7) lights while
playing and the Peak LED (#6)
flashes occasionally.
9. Bass adjusts the output level of
the low frequencies and offers a cut
or boost of 12dB at 70Hz.
10. Low Mid adjusts the output
level of the lower midrange frequencies and offers a cut or boost of
12dB at 300Hz.
11. High Mid adjusts the output
level of the upper midrange frequencies and offers a cut or boost of
11dB at 1.5kHz.
12. Treble adjusts the output level
of the high frequencies and offers a
cut or boost of 14dB at 7kHz.
13. Master controls the overall output level of the amplifier and the
level of the signal at the
Headphones jack (#15).
14. Line Out supplies a mono signal for connecting to a mixing console, tape recorder or external
amplifier. The signal is pre-Master
and post-EQ.
15. Phones allows the connection
of a pair of stereo headphones for
private practice sessions. The internal speaker is disconnected whenever headphones are used.
16. Power light indicates the amplifier is turned on by glowing an iridescent blue color.
17. Power switch is used to turn
the amplifier on and off.
18. Power cord (rear panel, not
shown) connects the amplifier to a
suitable source of A.C. voltage. This
is a grounded, three-wire cord and
must be connected to a properly
grounded outlet. DO NOT attempt
to defeat the ground connection
of the power cord! If your amp was
purchased outside of the United
States, see the sticker next to the
A.C. connector for its power ratings.
Follow the above guidelines.
Thank you for selecting the Ampeg Rocket Bass amplifier. Inspired by the classic Ampeg
bass amps of the sixties, this easy-to-use amplifier represents Ampeg’s quest to provide you
the finest instrument amplification systems available. In order to get the most out of your
new amplifier, please read these instructions before its use.
