The Tonebone Classic design follows the way a guitar amplifier works
whereby the input DRIVE is akin to the input channel volume, while the
LEVEL control acts more like a master volume control.
As such, the DRIVE control provides overall input gain to the distortion
circuit. This works in conjunction with the 3-position DRIVE switch that
controls low, mid or high distortion range settings. At low settings,
the Classic creates lighter rock & roll tones like the sounds you would
hear from Keith Richards or the cleaner side of Hendrix. In the mid-distortion
range, Stevie Ray Vaughan and Eric Clapton type tones come alive. At the
higher distortion settings, Eddie Van Halen to Eric Johnson type solo
tones can be created while big chunky rhythm tones from Boston to ZZ Top
to Deep Purple are also easily attained.
The Tonebone Classic employs active post-distortion equalization for
maximum flexibility. Tone shaping is performed with three controls and
two switches thus allowing the guitarist to dial in the type of tonal
structure that may be desired.
HIGH and LOW equalization are extremely active providing up to 15dB of
gain control. These work in conjunction with the TOP-END and MID-BOOST
controls. Overall shaping begins with the TOP-END control with choice
of Dark, Normal or Bright settings which are used to compensate for the
tonal characteristics of the amplifier. The FILTER control overlaps the
high-end with a subtle roll-off to further compensate for overly bright
amplifiers.
The MID-BOOST switch is used to fatten-up single coil pick-ups or to add
'meat' to the tone for additional cut during soloing. The Classic's mid-range
frequencies have been carefully selected to work with popular amplifiers
like Twins and Marshalls. These settings are extremely effective at compensating
for 'clean' oriented channels on classic tube amplifiers.
