Important Safeguards and Precautions
All Ampeg products are designed for continuous safe operation, as long as common sense is used and
steps are taken to help avoid certain problems. Abiding by the following rules can help prevent damage to
your amplifier, yourself and others.
• The amplifier is equipped with a three-pronged AC power cord. To reduce the risk of electrical shock,
NEVER remove or otherwise attempt to defeat the ground pin of the power cord.
• Connect the amplifier ONLY to a properly grounded AC outlet of the proper voltage for your amp.
• Avoid sudden temperature extremes, rain and moisture. Also, avoid sudden and intense impact. (If
the unit has been subjected to any of the preceding abuses, have it looked at by an authorized service center.)
• NEVER set the amplifier on a support that might give out under its weight.
• Always keep the total speaker impedance at or above the rated load.
• Unplug the amplifier before cleaning it. NEVER spray liquid cleaners onto the amplifier. Wipe it with
a slightly dampened, lint-free cloth to remove dirt and film.
• Don’t use the amplifier if it has sustained damage to the chassis, controls, or power cord. Refer the
unit to an authorized service center for inspection.
• Amplifiers capable of producing high volume levels are also capable of inflicting permanent hearing
loss or damage, if the exposure to such levels is prolonged. Such damage is progressive and irreversible!

The Front Panel Controls and Their Use
4 5 6 7 8 103 12 13 14 1521 9 11
1. INPUT: Connect your bass here
using a standard shielded instrument
cable.
2. 15dB PAD: When engaged, this
switch cuts the input signal level by
15dB, allowing you to set the Gain
control (#4) for the best signal to noise
ratio. (If your bass has high-output
pickups or active electronics, you
should use the Pad.)
3. PEAK LED: This LED lights whenever any preamp stage is near clipping. Adjust the Gain control (#4) until
a strong signal from your bass causes
this LED to flicker.
4. GAIN: This serves as the input level
control for the amplifier. For the best
signal to noise ratio, set this control so
the Peak LED (#3) flashes when you
hit your strings hard.
NOTE: If the Peak LED stays on with
the Gain at a low setting, use the 15dB
pad (#2) to cut the input signal, then
readjust the Gain.
5. BASS: The primary low frequency
control. This knob allows for a range of
8dB of cut or boost at 50Hz.
6. ULTRA-MID: The primary midrange
control. Rotate the knob to the left of
center for a “contoured” sound (more
distant, less midrange output) or to the
right of center for a sound which really
cuts through.
7. TREBLE: The primary high frequency control. This knob allows for a range
of 12dB boost or 19dB of cut at 5kHz.
8. MASTER: Set the overall output
level of the amplifier with this control.
The Effects Loop and Balanced Out
(#22-26) are not affected by the Master
control.
9. LIMITER SWITCH: The amplifier
uses an internal Optocoupler Limiter to
help keep the power amp’s output
“clean” at extreme volume levels. (All
amplifiers may begin to clip their output signals as they approach maximum output levels, resulting in potentially damaging distortion.) To engage
the Limiter, press in the Limit switch.
Playing at full power with the Limiter off
will give you increased output power,
but the sound may be distorted. Use
discretion when playing without the
Limiter.
10. LIMIT LED: This LED will flash any
time the internal limiter circuit is called
upon to keep the amplifier’s output signal clean. This shows that the amplifier is nearing full output and the limiter
is keeping it from clipping the output
signal.
11. EQ ON SWITCH: Press this switch
IN to activate the Graphic EQ.
12. EQ ON LED: This LED lights when
the Graphic EQ is active.
13. GRAPHIC EQ: These slide controls allow you to adjust the output of
the frequencies shown above each
control. The center position of each
control is flat (no boost or cut).
14. POWER ON LED: This LED lights
when the POWER switch (#15) is ON.
15. POWER SWITCH: This heavyduty rocker switch applies the power to
the amplifier: the amp is ON in the up
position, OFF in the down position.

16. FAN: This temperature controlled,
variable speed fan draws cool air into
the amplifier, forcing heat out through
the exhaust vents (also on the rear
panel, between the speaker jacks and
the power amp in jack). Never block the
vent holes or the fan openings.
NOTE: It is not uncommon for the fan to
remain off when the amplifier is first
powered up.
17. FUSE: This protects the unit from
damage due to overload conditions or
power line surges. If the fuse blows,
replace it only with the same size and
type.
18. AC LINE IN: Firmly plug the supplied AC power cord into this socket,
pushing it in until it is fully seated. Plug
the male end of the cord into a grounded AC outlet. DO NOT DEFEAT THE
GROUND PRONG OF THE AC PLUG!
19. SPEAKER OUTPUTS: Use these
jacks to connect the amplifier to your
speaker(s) using cables terminated with
1/4” plugs. Always use high-quality
speaker cables for these connections.
NOTE: When connecting multiple
speaker cabinets to the amplifier,
keep the overall impedance at or
above four ohms! The following chart
shows the total impedance load when
connecting speaker cabinets in parallel:
20. POWER AMP IN: This mono jack
allows you to feed the preamp output of
another amplifier to the input of the
internal power amp. This disconnects
the SVT’s preamp.
21. PREAMP OUT: A post-EQ signal
may be taken from this jack to be sent
to the house mixing board, recording
console or external power amplifier.
22. EFFECTS RETURN: To use an
external effects device, connect the
OUTPUT of the device to the Return
jack using a shielded cable. This feeds
the processed signal into the amp’s
Master section.
23. EFFECTS SEND: Connect the output from the Send jack to the INPUT of
your effects using shielded cable. This
sends a post-EQ signal to your effects.
24. -20dB SWITCH : This control
adjusts the output level at the Balanced
Line Output jack (#26). The control
works independently from the front
panel Master control. Pushing the
switch in activates the -20dB pad,
allowing use of microphone inputs on a
mixer without overdriving the inputs.
25. PRE/POST SWITCH: You can
select either Pre or Post EQ for the signal at the Balanced Out jack (#26) with
this switch. With the switch in the OUT
position, the signal at the jacks will be
Pre-EQ. This is a direct output not
affected by any EQ or boost settings.
With the switch in, the signal is Post-EQ
and is controlled and modified by the
tone controls, Graphic EQ, and Effects
Loop.
26. BALANCED OUTPUT: This XLRtype connector supplies a balanced
preamp output signal for connecting to
a house mixing board, recording console or external amplifiers with balanced inputs. The signal can be set to
Pre or Post EQ by the back panel
Pre/Post switch (#25). The level can be
adjusted for either mic or line type
inputs using the -20dB switch (#24).

IMPORTANT NOTE ABOUT CERTAIN EXPORT
UNITS: In some areas 1/4” speaker jacks are not
acceptable for use on amplifiers capable of high output power levels. For this reason the Speaker jacks
on your amplifier may resemble the illustration to the
right. Connect the amplifier to your speaker(s) using
cables rated for very high output power, terminated
with the appropriate connectors.

Some Suggested Settings
JAZZ:
ROCK:
COUNTRY:
FUNK “POPPING:”
The setting of the Gain and Master controls depend on your bass, on your
playing style, and on how loud you want it! The Graphic EQ can be used
to compensate for room acoustics, to “fine tune” your sound, and as a
“second channel” to be kicked in when needed for soloes and riffs.

Troubleshooting
In the unlikely event that your SVT-GS Gene Simmons Punisher should stop working properly (or just stop working), take
a few minutes to troubleshoot it before you call for service. You can save yourself a lot of time and sometimes money by
doing it yourself, and often the cure for the problem is something quite simple.
If the problem isn’t covered above, or if the steps led you here, then contact your Ampeg dealer for service information. Also, you should refer your amp for servicing if it gets dropped, has liquid spilled into it, or sustains damage to its
power cord.
