036: Tube PreAmp Modeling
This effect simulates a two-stage vacuum tube preamp.
You can make individual settings for two vacuum
tubes connected in series. This lets you create the
warm sound typical of vacuum tubes.
TUBE PREAMP1
Low Cut [Hz] [Thru, 21…8.00k]
Sets the cutoff frequency for the low cut filter of stage
1.
High Cut [Hz] [53…20.00k, Thru]
Sets the cutoff frequency for the high cut filter of stage
1.
Gain [dB] [–Inf, –38…+24]
Sets the input gain for stage 1.
Saturation [%] [0…100]
Sets the input/output response for stage 1. p.796.
Bias [0…100]
Sets the bias voltage for stage 1. p.796.
Phase [Normal, Wet Invert]
Turns phase reversal on/off.
With the Wet Invert setting, the phase of the signal will
be inverted between stage 1 and stage 2. Since “Bias” is
applied to the inverted signal in stage 2, this will
change the tonal character.
TUBE PREAMP2
Low Cut [Hz] [Thru, 21…8.00k]
Sets the cutoff frequency for the low cut filter of stage
2.
High Cut [Hz] [53…20.00k, Thru]
Sets the cutoff frequency for the high cut filter of stage
2.
Gain [dB] [–24.0…+24.0]
Sets the input gain for stage 2.
Saturation [%] [0…100]
Sets the input/output response for stage 2. p.796.
Bias [0…100]
Sets the bias voltage for stage 2. p.796.
Output Level [dB] [–48.0…+0.0]
Sets the output level.
OUTPUT
Wet/Dry [Dry, 1:99…99:1, Wet]
Sets the balance between the effect and the dry input.
Source [Off…Tempo]
Selects a modulation source for Wet/Dry.
Amount [+/–100]
Sets the modulation amount for Wet/Dry.
037: St. Tube PreAmp Modeling
This is similar to “036: Tube PreAmp Modeling”, but in
stereo.
For more information, see “036: Tube PreAmp
Modeling” on page 795.
038: Mic Modeling +PreAmp
This effect simulates a mic and vacuum tube preamp.
You can choose from various types of mic and
positions to create differing sonic characters.
