Description Product Description The Chandler Limited 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 â¨the GAV19T circuits are either new circuits developed by Chandler Limited or highly modified vintage circuits. The tube compliment is two â¨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 â¨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 â¨pedal that can be used to add sustain and presence.
