Tube Voicing
Selects basic character of tube sound by configuring the four tube stages and biasing them
for the proper gain and interstage EQ. There are ten Voicings available:
Table 1: Tube Voicings
1 Crystal Clean
2 Spanky Clean
3 Fat Clean
4 Vintage Brown
5 Warm Vintage
6 Dynamic Vintage
7 Warm Hi Gain
8 Dynamic Hi Gain
9 Ultimate Hi Gain
10 Fat Hi Gain
Drive & Master Level
Controls amount of signal fed to tube preamp.Use Master Level to balance relative levels of
different User programs.
Drive (0/100): Determines the amount of gain in the tube
preamp.
Master (0/100): Sets output level from tube preamp into other
sections.
OD [Overdrive] (0/100): Available only when Hi Gain tube Voicings
(7-10. see above) are selected. Determines
how extreme distortion generated in the preamp is.
Compressor
The Compressor is the first stage a signal reaches from the input jack, preceding the tube
preamp.
Status (In/Out): Switches Compressor in and out of the signal path.
Ratio (1.5:1/30:1): Sets compression ratio (increase in output for a given increase
in input). Available values are: 1.5:1, 2:1, 3:1, 4:1, 6:1, 8:1,
10:1, 15:1, and 30:1.
The higher the compression ratio, the more "squeeze" (gain
reduction) is applied to the signal.
Threshold (0/100): Found on screen 2. The Compressor reduces gain (squeezes)
signals exceeding the Threshold value, and increases gain
(amplifies) signals below the Threshold. The COMP THRESH
LED will light whenever the signal exceeds the Threshold and
Compressor Status is set to "In".
Gain (0/100): Found on screen 2. Sets the amount of gain
applied to the compressor output to make up for level lost as a
by-product of compression. Lower Thresholds and higher
Ratios will generally necessitate higher Gain settings. It is
recommended that Gain be adjusted until the basic signal level
does not appear to change when the Compressor is switched
in and out.
