as outlined above.
Treble Level
Adjusts the high frequency level of the sound generated by your instrument. Start
at 0 (flat) and adjust to taste. Turning clockwise boosts the level of highs up to
+16dB, turning counterclockwise cuts the level of highs down to -16dB.
Note: We always recommend using the minimum amount of bass and
treble tone shaping to achieve the sound you desire. These controls
are very powerful; they can greatly cut or boost the gain of the lower
and higher frequencies. If an extreme setting of this control is
required to achieve a balanced sound you may have an issue with
your Mid Level and Mid Frequency control settings, or, with your
guitar pickup, leads, volume pedal.
After setting the Bass Level, Mid Level, Mid Freq and Treble Level
controls we suggest you note the settings.
Blend
Only set this control after you have set all the other tone controls.
This is to
be used as a sonic “shading” control and, like any seasoning, a little goes a long
way. Start at 12 o’clock. Clockwise yields a “Mooney” bright aggressive sound;
counter clockwise gives you a mellow, darker tone.
The Blend control is initially one of the most confusing settings to
understand… until you start using it. After using the combo for a few
gigs you may find it’s the only tone control you need! Once the bass,
mid and treble controls have been set the amplifier might be
considered as calibrated to your style and guitar sound.
As you rotate the Blend control clockwise you’ll notice the treble
increases and the bass decreases.
As you rotate the Blend control anti-clockwise you’ll notice the
treble decreases and the bass increases.
This control is like ‘one stop shop’ compensating for the affect the room
acoustics has on the overall sound. It’s quite remarkable how a small
tweak of this control can sweeten up your sound in a gigging situation.
And being a single control it’s easy to remember where you started before
you started tweaking.
Normally, players leave this control at zero and only adjust it slightly
b1 or -1 to compensate for the venue (room size, crowd size,
bandstand configuration (even for relative humidity changes, as sound
propagates differently with humidity changes).
