Introduction
We know you don’t like reading owners manuals, but you’ve just purchased one of the
finest guitar amplifiers around, and we want to tell you about it! So, before you plug in
and start strumming and shredding, we’d like to suggest you take just a few moments to
scan these pages. We’ll make it as painless as possible, we promise—and, who knows, you
might just pick up a tip or two.
The Hartke G15, G15R and G30R amplifiers have been designed for modern guitar play-
ers looking for a new sound that respects the tone of a classic amp. And don't let their
size confuse you (Nigel), these combos are powerful amplifiers, with an amazingly wide
variety of tone, allowing guitar players to rediscover the sound from a favorite old vintage
amp, or dial up a new sound that’s uniquely their own. All three models feature Hartke's
G Series burnin'-hot pre amp, 2-channel section for clean and dirt and a matching Hartke
GXL speaker custom voiced for harmonic overtones that add to the warmth and richness
of the sound. The G series Channel 1 circuitry provides a super clean classic tone and can
be slightly over driven for a great roots-rock rhythm tone. Channel 2 has high GAIN for
smooth to shredding distortions. Plus, the versatile, and musical, equalizer provides BASS,
TREBLE plus MID (G30R only) to shape the sound the best complements your playing style.
On the G15R and G30R, special attention was also taken in designing a Reverb effect that
you actually want to use! The warm spring sound has been optimized by carefully selecting
both the electronic and mechanical components. The 2-channel per-amp design with foot
switch control lets you quickly and easily switch from rhythm to lead. The G series feature
a steel amplifier chassis, enclosures made of rugged Plywood and MDF construction, with
durable vinyl covering. The G Series combos are perfect amplifiers for use in small or large
venues ( mic'd-up into a large PA!). Plus, the CD input and dedicated headphone output
makes them awesome practice amps! There are three different G Series models, and this
manual covers the G15, G15R and G30R combos. Whichever of these models you’ve pur-
chased, you’re assured of robust construction and that great Hartke sound.
In these pages, you’ll find a detailed description of the many features of your G Series
Amplifier, as well as a guided tour through its front and rear panels, step-by-step instruc-
tions for setting up and using the amp, plus full specifications. You’ll also find a warranty
card enclosed—please don’t forget to fill it out and mail it so that you can receive online
technical support and so we can send you updated information about this and other
Hartke and Samson products in the future. Also, be sure to check out our website (www.

VOLUME - This is the overall volume control for CHANNEL 1.
CH1 LED – When this light is illuminated, CHANNEL 1 is selected.
CHANNEL SWITCH - The switch allows you to select either CHANNEL 1 or CHANNEL 2.
CH2 LED - When this light is illuminated, CHANNEL 2 is selected.
CRUNCH - CHANNEL 2’s pre-amp level control used to dial up tube overdrive tone for clas-
sic metal distortion, shredding leads and fat modern chunk.
7.
VOLUME (CH2) - This is the overall volume control for CHANNEL 2.
8. BASS - This tone control allows you to adjust the low frequency tone of your amp.The
G Series tone controls use electronic circuits based around those of the best sound-
ing classic amplifiers.The normal BASS tone (that is, flat response) is when the knob
is at the 12 o’clock (“5”) position. As it is turned clockwise from the“5”position, the
frequency area is boosted; as it is turned counterclockwise from the“5”position, the
frequency area is attenuated.

9. MID (G30R only) - This tone control allows you to adjust the mid-range frequency
tone of your amp.The G Series tone controls use electronic circuits based around
those of the best sounding classic amplifiers.The normal MID tone (that is, flat
response) is when the knob is at the 12 o’clock (“5”) position. As it is turned clockwise
from the“5”position, the frequency area is boosted; as it is turned counterclockwise
from the“5”position, the frequency area is attenuated.
10. TREBLE - This tone control allows you to adjust the high frequency tone of your amp.
The G Series tone controls use electronic circuits based around those of the best
sounding classic amplifiers.The normal TREBLE tone (that is, flat response) is when the
knob is at the 12 o’clock (“5”) position. As it is turned clockwise from the“5”position,
the frequency area is boosted; as it is turned counterclockwise from the“5”position,
the frequency area is attenuated.
11. REVERB (G15R and G30R only) – The control knob used to set the level of the internal
Spring Reverb.
12. CD IN - Your G Series amplifier features a CD input which you can use with a portable CD
player, cassette, mini disk or MP3 player. You can use the CD input to jam with pre-recorded
tracks or to learn a riff from a favorite recording.
13. PHONES - Connect any stereo headphone (600 ohms or less) to this standard 1/4" stereo
jack. When a plug is inserted into the headphone jack, the speaker output is disconnected,
allowing you to use your G Series as a practice amplifier. The level of the signal sent to the
headphones is determined by the setting of the Volume knob—at the point where a con-
nected speaker would clip, the headphones will clip.
WARNING: Because even the smallest G Series amplifier is capable of generating extremely
high headphone signal levels, always start with the Volume knob at minimum and then
slowly turn it up. In particular, a clicking sound is an indication of distortion and possible
damage to the headphones (and/or your hearing!); don’t let things get to that point!
14. POWER switch - Use this to power the G Series on or off. When powered on, an LED inside
this switch is lit.

Setting Up and Using Your Hartke G Series
Guitar Amplifier
1. Remove all packing materials (save them in case of
need for future service) and decide where the amplifier
is to be physically placed. To avoid potential overheat-
ing problems, make sure that the rear panel is unob-
structed and that there is good ventilation around the
entire unit.
2. Before you plug-in the power cable, be sure the
POWER switch is in the off (down) position. Plug-in the
3-pin AC plug into any grounded AC socket. Don’t turn
the G Series on just yet, though.
3. Use a standard music instrument cable to connect
your guitar to the INPUT jack on the front panel.
4. On the front panel of the G Series, turn the VOLUME
on CHANNEL 1, and CRUNCH and VOLUME on CHANNEL
2 controls to their minimum (fully counterclockwise)
position. Set the BASS, TREBLE and MID controls to their
“5”position.
5. Press the front panel Power switch in order to turn on
your G Series amp; the switch will light up to indicate
power has been applied.

6. Press the front panel CHANNEL SWITCH to select
CHANNEL 1. Note: If a footswitch is connected to the
rear panel FOOTSWITCH input jack, you will need to
change the channel using the foot switch.

7. Set the output of your guitar to maximum and then,
while playing, slowly turn the G Series CHANNEL 1
VOLUME control up until the desired level is achieved.
You will get a nice clean tone when using just VOLUME
for level, so set it to the level you like.

8. Adjust the BASS and Treble equalizer controls to taste.
(When you get a great setting that complement your
instrument and playing style, it’s a good idea to write it
down for future use.)
9. Now, press the CHANNEL SWITCH (or the footswitch) to
select CHANNEL 2.
10. Set the CHANNEL 2 CRUNCH to “10”position (fully
clockwise) and then, while playing, slowly turn the G
Series CHANNEL 2 VOLUME control up until the desired
level is achieved.
NOTE: With the CRUNCH control on “10”you will get the
most overdrive from CHANNEL 2. You can turn down the
RUNCH control for less distortion.
11. Adjust the BASS, MID (G30R only) and TREBLE equal-
izer controls to taste. (When you get a great setting that
complement your instrument and playing style, it’s a
good idea to write it down for future use.)
12. Your G Series amplifier features a CD input which you
can use with a portable CD player, cassette, mini disk or
MP3 player to jam with pre-recorded tracks or learn a riff
from a favorite tune. In fact, you can plug any line level sig-
nal into the CD input including the signal from a keyboard
or drum machine. Connect the CD player or other Line level
device to the CD Input using stereo 1/4-inch to RCA cable.
You will want to use the volume control on the CD player or
other Line level device to set the balance between the track
and your guitar. So, start with the volume control all the
way down and slowly raise it until you reach a good balance
with your guitar.
13. Test the headphone output by turning the Volume
control to its minimum (fully counterclockwise) position
and then connect a standard stereo headphone to the front
panel Phones jack. While playing your guitar, slowly turn
the Volume control up—you should hear sound from the
headphones and none from the connected speaker.

Using the Footswitch Jack and Effects Loop
14. The Hartke G30R has a footswitch jack located on the
rear chassis panel. You can connect a standard footswitch
terminated with a 1/4-inch phone plug, readily available at
your musical instrument retailer, so that channel switching is
hands-off easy.

G Series Sample Settings
The G Series combos are powerful amps with a lot of personality. The amplifiers offer guitarists
a wide range of sounds and after playing just a short time, you’ll find the tone that's perfectly
suited for your playing style and your sound. To get you started, try some of the samples settings
below. Don't forget to add a little (or a lot) REVERB to any of the settings. Remember, the G
series use different speaker systems, plus different guitars are made of different wood and have
different pick-ups, so the sound will vary a little bit on each individual set up. But still, the sample
settings will get you close enough, so you can use you ear to tweak up the sound that’s perfect
for you.
On page 12 you'll find blank templates of Channel 1 and Channel 2. Use these templates to write
down the settings for your favorite sounds. Feel free to photocopy or scan the template page if
needed.
