RedPlate TruVerb Standard Operations Guide

CLEAN PREAMP SECTION
The Clean Preamp is designed to imitate (and surpass) all of the “classic” guitar amp preamps.
The TruVerb gives the player the ability to do three unique things:
1. Shift the midrange center point frequency via the Mids control.
2. Select the amount of Bass gain appropriate to your guitar choice via the Lows control.
3. Bypass the tone stack by doing a full stack lift when bass control is rotated to zero.
Bright Switch
– Center = OFF, Down = sound of new strings, Up = normal Bright response.
Volume
–
Typical setting is between 3 and 5 but experimentation is encouraged.
Treble Control
-
Adjusts highs
Mids Selector
– A six position rotary switch, it steps through 5 progressively fatter positions of
the midrange center frequency and achieves maximum fat midrange by engaging a mid boost in
position 6
Middle Control
–
Controls the amount of Midrange frequencies, somewhat interactive with
the Bass Control. Pulls to enable “Deep” which scoops some midrange frequencies and
emphasizes Bass (makes your electric sound more like an acoustic).
Lows Selector
– A four position rotary switch, it steps through 4 progressively fatter positions
of bass gain.
Bass Control
– Sets the amount of bass frequencies. Can be rotated to zero where it clicks off
for a full tone stack lift.
MASTER SECTION
Reverb Control
- Sets the amount of reverberation effect, takes the reverb out of circuit when
rotated to zero (there will be a slight volume and tone change).
Presence Control
– The presence circuit uses global negative feedback to remove low
frequencies which frees up bandwidth for more midrange and highs. Think of it as a tone control to
balance the relationship between highs and lows, especially when the amplifier is naturally
