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.
