INPUT SENSITIVITY SWITCH
Sensitivity
Switch is placed above the Input Jack. This
2-position switch varies the sensitivity and impedance of
the amp’s input.
•
High : Input impedance 1 M Ω , no signal
attenuation
•
Low : Input impedance 120k Ω , 6db signal
attenuation
GAIN & HARMONICS CONTROL
This section controls preamplifier’s gain structure
and distortion characteristics.
LEVEL - adjusts preamp output signal level to the
EQUALIZER
Gain – this 3-position switch operates on the 1
st
gain stage and provides
basic gain settings:
•
Bright , left, +4db boost at 4kHz, onset at 400Hz
•
Norm , center, standard setting
•
Boost
, right, + 4db gain full range boost
An additional gain control is activated by the Footswitch: 2
nd
preamplifier
stage gain can be boosted by 4db for added crunch on clean sound.
DRIVE - controls overdrive characteristics in the preamplifier’s 3
rd
gain
stage. Adjusting the gain varies the amount of distortion.
This 3
rd
gain stages can be bypassed using the footswitch for clean to
crunch sound.
LEVEL control is signalwise placed after the DRIVE control. It has no effect
on the preamp distortion thus allowing the GAIN & DRIVE setting to be very
sensitive to the guitar’s volume control. However, LEVEL setting has
influence on how much, if any, additional distortion will be generated in the
EQUALIZER . This, together with MASTER Volume affects output power amp
distortion.
Harmonics switch allows a choice of 2 different distortion characters:
•
2/3, mostly even harmonics in the distortion spectrum
•
3/2, mostly odd harmonics in the distortion spectrum
The difference between these 2 switch positions is most audible when
playing with moderate DRIVE and GAIN levels in the range of clean/dirty to
