RPx400’s Effects
About the Effects
The RPx400 can be thought of as several different “virtual” amplifiers and individual, hi-tech stomp boxes in a
single programmable package. With stomp boxes, the order in which they are connected can drastically affect
the overall sound quality. The RPx400 has placed the effects in an order for optimum sound quality. The fol-
lowing diagram shows the order of the effects.
Effect Definitions
Each effect within the RPx400 can be programmed to suit your personal taste and application. Understanding
how these effects alter the sound, and how each parameter alters the effect helps you achieve the sound you
are looking for. The following overview of the RPx400’s effects outlines what each effect and parameter does.
Pickup/Wah
The Pickup Simulator provides the thick tone of a humbucker pickup to a guitar with single coil pickups,
or the bright edgy sound of a single coil pickup to a guitar with a humbucker. This lets you have the best
of both worlds without having to change guitars during a performance.
Wah is an effect controlled by the Expression Pedal. As the Expression Pedal is rocked back and forth, it
makes the guitar sound as if it is saying “Wah.” The Wah is engaged and disengaged by applying pressure
to the V-Switch located under the toe of the Expression Pedal. See Page 21 for more information regard-
ing the V-Switch.
Pickup Off/Type - The Number 1 Knob selects the type of Pick Up to be be simulated. Values include:
SC>HUM (Gives a single coil pick up the warm tone of a humbucker), and HUM>SC
(Gives a humbucker the unique sound of a single coil), or turns Pickup Simulation off.
Wah On/Off- The Number 2 Knob turns the Wah effect on or off.
Wah Type - The Number 3 Knob selects the type of Wah. Values include:
CRY (Cry Wah is a traditional
sounding Wah),
BOUTIQ (Boutique Wah is a wide sweeping Wah with a more modern sound)
and
FULRNG (Full Range Wah sweeps the entire spectrum of audible frequencies).
Wah Minimum - The Number 4 Knob is used to select the minimum point the Wah reaches in the toe up
position of the Expression Pedal. Ranges from 1 to 99.
Wah Maximum - The Number 5 Knob is used to select the maximum point the Wah reaches in the toe
down position of the Expression Pedal. Ranges from 1 to 99.
