SWR Sound Mini-Mo' Preamp With Mo' Control 2 Master Footswitch Controller - Manual (Page 12)

TREBLE CONTROL
The Treble control is a shelving-type tone control that cuts or boosts high frequencies up to 12 dB in
either direction. Starting from mid-position ("flat"), turning the Treble control counter-clockwise cuts the
highs, while turning the control clockwise boosts the highs. The shelving point for this control is about 2
KHz.
MIDRANGE CONTROLS
Your Mini-Mo' Preamp comes equipped with two different controls for setting the amount of midrange
present in the preamp section: one for boosting and cutting the level of midrange, and another for
setting the specific midrange frequency that will be adjusted in level.
MID LEVEL CONTROL
The Mid Level control cuts or boosts up to 12 db the frequency set by the Mid Frequency control.
Starting at mid-position, turning the Level control counter-clockwise cuts the desired tone. Turning the
Level control clockwise boosts the desired tone (set by the Mid Frequency control). When the level
control is set at mid-position ("center-click"), turning the frequency control will have no effect on the
sound.
To find the midrange area you are looking for:
1. Adjust the Mid Level control to the full boost or cut position.
2. Rotate the Mid Frequency control until the desired area you wish to cut or boost is found.
3. Adjust the Mid Level control to the desired amount of cut or boost.
MIDRANGE FREQUENCY CONTROL
The Midrange Frequency control sets the area that is to be cut or boosted by the Midrange Level
control. If the Midrange Level control is set at mid-position, turning the Frequency knob will have NO
affect.
Some hints: If you need to "cut through" the band a little more, try boosting 200 to 400 Hz. If you like a
more transparent or "scooped" sound, try cutting at 800 Hz. The midrange controls are especially useful
in controlling fretless basses and their inherent qualities.
BASS CONTROL
The Bass Control is a shelving-type tone control that cuts or boosts the low frequencies up to 12 dB in
either direction. Starting from mid-position (flat), turning the control counter-clockwise cuts the bass
response, while turning the control clockwise boosts the bass response. Shelving point for this control is
about 80 Hz.
A FINAL NOTE ON THE PREAMP CONTROLS A FINAL NOTE ON THE PREAMP CONTROLS: Select each control to your taste, but remember that the
more heavy EQ you have on the front end, the more EQ you will have going into the Mini-Mo' Preamp
effects––sometimes a good thing, sometimes not. As always, your own musical preferences will come
into play.
PREAMP TUBE
Though not a "control" function of the preamp, you should be aware that the preamp in your SWR
Mini-Mo’ Preamp is a tube preamp. The tube is a specially selected 12AX7 and should not require
replacement for one to three years, depending on usage. The tube is also used for another key function
in the unit, specifically...
OVERDRIVE
Yes, the Mini-Mo' Preamp Overdrive is a Tube Overdrive. Just because there's no 50-pound tube power
amp in the Mini-Mo' Preamp doesn't mean you can't get the sounds of tube-driven distortion! It works
