GAV19T Guitar Amplifier

Chandler Limited GAV19T wins Guitar Player Magazine Editors' Pick Award
- Chandler Limited's GAV19T is an all-tube, 19-watt guitar amp in the
 vein of such vintage English classics as Selmer, Watkins, Marshall and
 Vox.  While this amp borrows some tones from the classics, the heart of 
the GAV19T circuits are either new circuits developed by Chandler
 Limited or highly modified vintage circuits. The tube compliment is two 
EL84s, an ECC83, ECC803, and EZ81.

The control panel of this amp is non-typical when compared to vintage
 amps.  The GAV19T controls allow you to change the bias of the gain stage
 for different character, as well as use the intensity switch to add 
sustain and grit. The drive controls function in the power amp section
 only and create distortion that never sounds weak or muddy.  The tone
 control is a Baxandall-style eq. It functions like a treble booster 
pedal that can be used to add sustain and presence. This amp is similar
 to many Chandler Limited products - full of fat, vintage tone!

All-in-all, the GAV19T is like other Chandler products - full of fat, 
vintage tone!


 The Bias effects only the bias of the pre-amp tube, allowing you to
 gently tweak its overall tone separately from the power section. You can 
run the tube hotter or colder and change the responsiveness of the amp
 as well as effecting the sustain and frequency response. #1 is slight
 over-biased, #2 is similar to a Marshall bias, #3 is similar to a
 Selmer, and #4 and 5 are under-biased and add sustain and character to 
the amp.

Tone Controls:
 The Tone section of the GAV19T is a Baxandall style that
 uses an ECC803 tube. Baxandall was chosen because it best preserved the 
natural tone of the amplifier. This section is set up to function as a 
treble boost pedal might be.  The boost is considerable and the range wide
and it can be used to smoothly drive the amp and color the tone.

 The drive portion of the GAV19T is a boost or overdrive circuit that works
 only on the power section of the amp. It is pretty widely known that 
power section distortion is a pleasing type of distortion so instead of 
adding pre-amp gain and distortion we used the power amp. The Drive has two controls. #1 is the amount of boost. #2 is the tone of
the boost. You can choose four selections or bypass.

The Tone selections are:

  • Treble Boost - as you might expect from a treble boost pedal.
  •  Full range - full frequency boost but with very low frequency filtered
Aggressive - drives a wide frequency range with an emphasis in the higher 
mid range.
  • Mids - drives the entire circuit with an emphasis on the lower mid

Tone - normal or intense:
 Slightly unbalances the matching of the push pull power section. It
 removes some low mids as well as making the tone more aggressive and
 adding some grit and attack to the sound.
