Samson G15 User Manual

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
