GW33 SYSTEM OVERVIEW
This section provides a brief overview of the GW33 — the basic structure of its various functions
and the memory system. Once you gain a general understanding of the internal workings of the
GW33 as given here, you’ll have the tools for taking full advantage of its features.
The diagram below shows the internal system of the
effects and other functions of the GW33.
The GW33 is equipped with a comprehensive set of
effects designed specifically for the guitar player. Up to
eight different effects can be used simultaneously. More-
over, a special Insert block lets you connect additional
external effect units to the multi-effect chain of the GW33.
Individual effects (excepting Noise Gate) can be turned on
and off as needed with the Pedal Switches and can be
quickly and easily adjusted with the Parameter Dials.
There are eight main effect blocks and a total of thirty-one
different effect types:
(Refer to the EFFECTS AND PARAMETERS section,
page 20, for more detailed descriptions and explanations
of these effects.)
With all these various effects, used individually or simul-
taneously, the GW33 has all you need to augment your
sound, whatever the application. Plus, flexible effect
bypass (on/off) functions give you even more realtime
control over the sound. A programmable Noise Gate is
also included for filtering out hum, hiss and other undesir-
able noise. (See page 29.)
