Texas Tone Ranger Owner's Manual 

 

The Texas Tone Ranger 

 

While the Texas Tone Ranger is inspired by the dynamic performance of the Marshall 18 Watt, the 
Ranger has actually very little in common with that great amp besides the chassis and cabinet.  We have 
added some unique touches and modern safety and construction methods. 

Vintage tube guitar amplifiers suffer from outdated electrical grounding methods.   Texas Tone

 guitar 

amps feature modern grounding techniques and three-prong electrical plugs for safe, low-noise 
operation.   Many amps from the 1950s also have very little clean headroom.   Special features allow the 
Texas Tone Ranger extra headroom when needed, or total tube amp distortion.  This allows the guitarist 
to get that sweet and creamy tube crunch, or to tame those vintage sounds, depending upon the control 
panel settings. 

The Texas Tone Ranger features two independent channels and controls. Both channels are augmented 
by shielded inputs and a shock-mounted first-stage preamp tube.  The left-side vintage channel features 
the unique Texas Tone

 Hi-pass/Low-pass Tone control that provides tone enhancements without 

affecting the volume control.  This channel provides a single gain stage with a traditional mid 1960

tube amp 

clean

 sound that can be cranked for tube amp crunch without being too loud for smaller 

venues, studio use, or practicing at home, and is very pedal friendly. 

This right-side channel

s gain stage is followed by a Gain control for the unique tone stack that is 

responsive and low loss, with Treble and Bass controls, with by a Volume control before the phase 
splitter.  By adjusting the Gain and Volume controls, the guitarist can get anything from clean and loud 
to smooth overdrive.  

From clean to dirty, this amp allows you to remain in control of your sound; you will be surprised at the 
variety of tones you can achieve with this amp.
