1. Input accepts a standard 1/4” instrument
plug from your bass.
2. Headphones allows the connection of a
pair of stereo headphones for private practice sessions. The internal speaker is disconnected whenever headphones are used.
3. Volume controls the overall output level
of the amplifier and the level of the signal at
the Headphones jack (#2).
4. Bass adjusts the output level of the low
frequencies and offers a cut or boost of
12dB at 60Hz.
5. Low Mid adjusts the output level of the
lower midrange frequencies and offers a cut
or boost of 11dB at 200Hz.
6. High Mid adjusts the output level of the
upper midrange frequencies and offers a cut
or boost of 11dB at 1.2kHz.
7. Treble adjusts the output level of the high
frequencies and offers a cut or boost of

8. Power light indicates the amplifier is
turned on by glowing an iridescent blue
color.
9. Power switch is used to turn the amplifier on and off.
10. Line Out (rear panel, not shown) supplies a mono, unbalanced signal for connecting to a mixing console, tape recorder or
external amplifier. (By using a TRS plug the
signal is balanced – tip is “+”, ring is “-”.)
11. 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.
