Rocktron Piranha - Manual (Page 6)

Pressing the DISTORTION button (L.E.D. on) switches the Piranha to the Distortion mode.
The Piranha provides two distortion modes - Classic Tube and Modern Tube. The
DISTORTION button is used to swicth between each mode.
When the DISTORTION button is lit (but not flashing) the Piranha is in the Classic Tube
distortion mode. This mode provides tones ranging from smooth, slightly overdriven rhythm
tones (at lower Gain control settings) to full tube high gain (at higher Gain control settings).
Pressing the DISTORTION button again switches the Piranha to the Modern Tube distortion
mode. (The DISTORTION button will flash quickly in Modern Tube mode.) Like the Classic
Tube mode, this mode also provides a wide range of tones, but also incorporates distortion
characteristics reflective of modern hard rock guitar sounds.
(7) BASS level control:
This control adjusts the amount of low band information in the Piranha output for the current
preset. Turning this control one step (or one "click") will display the current value for the
BASS level control without changing the current value.
(8) MID -/+ control:
This control adjusts the amount of mid band information in the Piranha output for the current
preset. Turning this control one step (or one "click") will display the current value for the
MID level control without changing the current value.
(9) MID FREQ control:
This control determines the mid band frequency that the MID -/+ control will adjust.
(10) TREBLE level control:
This control adjusts the amount of high band information in the Piranha output for the current
preset. Turning this control one step (or one "click") will display the current value for the
TREBLE level control without changing the current value.
(11) GAIN level control:
This control adjusts the amount of gain applied to the input signal for the current preset.
Turning this control one step (or one "click") will display the current value for the GAIN
level control without changing the current value.
(12) LEVEL control
This control is used to adjust the output level of the current preset. Turning this control one
step (or one "click") will display the current value for the LEVEL control without changing
the current value.
(13) OUTPUT LEVEL control:
The OUTPUT LEVEL control increases or decreases the overall output level of the Piranha -
independent of the LEVEL control.
(14) INPUT DRIVE control:
This control is an adjustable gain stage which feeds the input of the tube stages, and allows
for input level adjustment when switching between guitars which provide different output
levels (i.e. switching from a guitar with passive single-coil pickups to a guitar with active
humbucking pickups).
The INPUT DRIVE control also determines the maximum amount of distortion that a preset
can have, as higher levels of input drive will result in a higher potential distortion level.
Conversely, presets can also be globally "cleaned up" by reducing the input drive level.
(15) INPUT jack:
This standard unbalanced jack is used to provide input to the unit. For convenience, the
Piranha provides both front and rear panel mounted input jacks.
