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. See “Saturation
[%]” on page 798.
Bias [0…100]
Sets the bias voltage for stage 1. See “Bias” on page 798.
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]
High Cut [Hz] [53…20.00k, Thru]
Gain [dB] [–24.0…+24.0]
Saturation [%] [0…100]
Bias [0…100]
These parameters are identical to those for “TUBE
PREAMP1,” above.
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.
