GETTING STARTED
BOOST -
To set up the Level Boost, plug your instrument into the Input Jack (5), and
connect the Output Jack (6) to your amplifier, after connecting a +9/+12VDC power
supply to the DC IN to the DC IN (7). Turn the boost on using the footswitch (3), making
sure the LED (4) is ON (this indicates that the effect is active). Next, adjust the Boost
Level slider while toggling the footswitch (3) on and off, comparing the volume of the
direct signal with the boosted signal. Match the gain level as closely as you can to the
direct signal, then adjust the Level Boost slider to the desired amount of added boost
or cut. A suggested use of the boost is to leave it turned off until it’s time to solo, then
switch it on (3) for a quick level boost when you begin your solo. You can easily apply
this to ANY situation where you need two different, quickly accessible playing volumes.
VPF (Variable Pre-shape Filter) -
This filter boosts lows and highs, and cuts mids.
Some call this kind of effect a scoop, a smiley-shape EQ, or an enhance knob. It’s very
effective for slap bass, pick playing, and driving eighth-note rock. It’s off when it is all
the way counterclockwise—we suggest you start in that position and turn the filter up
gradually, to hear and understand what it does.
