Mesa/Boogie RECT-O-VERB 50 사용자 설명서

PAGE 4

As with most guitar amplifiers, the TREBLE control is the strongest of the three rotary tone controls. Its setting on the RECT-O 50
determines the blend and strength of the MIDDLE and BASS controls. Set high, it is the dominant control, thus minimizing the amount

of Mid and Bass that would be possible in the mix. Set low, the TREBLE becomes the recessive control and
a warmer, darker blend is produced. Dial with care. Subtle tweaking of this control tends to produce the best
results.

The MID control determines the blend of midrange punch and boldness. It also has a great deal to do with how a sound feels to play.
Setting the Midrange low scoops the attack, making the sound and feel more liquid and resilient. Setting the MID control higher
introduces more punch and authority, helping sounds cut through a mix better. Setting the Mids very high may make the strings feel

a little stiffer and less spongy. Keep this in mind when dialing up your sounds so that you can retain the best
feel on the strings, allowing you to always play your best.

In the PUSHED Mode, the MID control set low produces a sweeter, smoother clip and really allows this
sound to purr.  Try the GAIN control set at around 

 

 or so and the MID control set at around 

 

 to 

 

for a tasty blend of smooth dynamic overdrive. Add Treble to focus the attack and fatten with the BASS
control. Presence will “Open up” or compress this beyond vintage sound that howls with authenticity. This
has to be one of the best sounds in the RECT-O 50 !

At high Gain settings in either the Vintage Orange or Modern Red Modes, the MID control dials in punch and

aggression. For the tightest crunch chording, set the MID control high, say around 

 

 

.  To make single notes feel juicier and

more liquid, reduce the MID control to around 

 or so. In the Modern Red Mode, using the Mid higher and in conjunction with the

PRESENCE control also set high, delivers a down right ugly crunch that’s huge and angry - not fit for the meek!  This setting also
sounds great and becomes easier to play and more elastic feeling with the GAIN control set at 

 or higher.

This control blends in the lower frequencies and its effectiveness, again, depends on the setting of the TREBLE control. It should be
set with moderation as extreme settings in either low or high directions can produce an unbalanced tone. Be “especially” careful in

higher Gain settings of either channel. Too much Bass will cause a flabby unfocused sound.

Try setting the BASS control to 

 for clean sounds in the clean Mode and 

 or below when dialing up

high gain overdriven sounds in this Mode. In the LEAD Modes, try setting the BASS somewhere between

 and 

.  These settings will vary with the amount of Gain and Treble you have dialed up.
