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. GW33 Internal Structure 1 11 1 1 1 The diagram below shows the internal system of the effects and other functions of the GW33.
The Effect Structure of the GW33 Keep in mind as you use the GW33 that the structure of its effects is basically in a four-part hierarchy: 1) Effect programs, 2) Effect blocks, 3) Effect types, and 4) Effect parameters. An effect program consists of eight different effect blocks, all of which can be used simultaneously. A block includes 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 12 one or more effect types, one of which can be used at a time.

Clean, spacious sound with Cho.
GUIDED TOUR When using your GW33 for the first time, read through this short section of the manual. It guides you step-by-step in all basic operations: setting the instrument up, connecting it properly to other equipment, and playing the effect programs. SETTING UP AND PLAYING YOUR GW33 Once you’ve taken your GW33 out of the box and are ready to use it, you’ll have to make a few connections and follow some simple instructions on setting it up.
2 First, make sure that the power switch on the GW33 is off before making ANY connections. Plug the DC output cable from the supplied PA-3 adaptor (or another adaptor recommended by Yamaha) (Never use the PA-3B.) into the DC IN terminal on the rear panel, then plug the adaptor into a convenient AC outlet. CAUTION! ■ Do not attempt to use a different AC adaptor with the GW33. (See the precaution USE THE CORRECT POWER SUPPLY on page 3.) 3 Plug your instrument into the INPUT jack on the rear panel.
PLAYING WITH THE EFFECTS Now that you’ve set up your GW33 and have got sound out of it, let’s try playing with some of the effects. (If you haven’t already done so, read through the GW33 SYSTEM OVERVIEW section on page 7 for information on the basic structure of the GW33.) 1 First, make sure that the Play mode is enabled. Press p. PLAY 2 Let’s start with a clean chorus/delay effect. Use Pedal Switch 5 to select program number 15.
EDITING AN EFFECT PROGRAM AND SAVING IT The GW33 makes it extremely easy to adjust or change the sound of the effects. In this section, you’ll learn how to change the effect type and use the Parameter Dials to change effect settings. You’ll also learn how to compare the edited program with the original. Finally, you’ll learn how save the new effect program you’ve created. Editing an Effect Program 1 Select one of the User or Preset effect programs.
Comparing the Edited Effect Program with the Original You can compare the sound of the newly edited program with the sound of the original one. To do this, press the e button again (so that the EDIT/COMPARE lamp flashes). EDIT/ EDIT/ COMPARE COMPARE In this condition, you can hear the sound of the original effect program. You can also view the original parameter values by selecting the desired effect block with the y or n buttons and turning the Parameter Dials.
Saving an Effect Program Now that you’ve created your own original effect program, you will want to save the settings to a program number, so that you can recall your new effect program in the future. (For more information on saving effect programs and other matters relating to memory, see the SYSTEM OVERVIEW section on page 7.) 1 If you’ve continued from the last section and have new settings you want to save, press the s button.
REFERENCE This section of the manual explains briefly, yet completely, all of the features and functions of the GW33. Refer to it when you need information about a specific feature or function. SELECTING EFFECT PROGRAMS OPERATION 1 With the Play mode enabled (press p ), first select the desired bank of programs. ● To select one of banks 1 – 5 To select one of banks 1 – 5, press the Bank Pedal Switch once, then press the appropriate Pedal Switch 1 – 5.
TURNING ALL EFFECTS OFF ﾑ BYPASS FUNCTION While playing, you can instantly get a clean, unprocessed sound by using the Bypass function. This effectively cancels all currently active effects to give you a “dry” sound. ● To use the Bypass function: Simultaneously and firmly press and hold down Pedal Switches 2 and 3. Keep holding them down (for roughly one second) until “bP” (Bypass) appears in the BANK/ MEMORY indicator.
EDITING EFFECT PROGRAMS Effect programs can be edited in the Edit mode. Once you’ve edited a program, you can save it to a User memory location. (See SAVING EFFECT PROGRAMS on page 31.) CAUTION! ■ Be careful not to press the p button at any time during editing. Doing so will call up the original effect program’s settings and erase all settings you had made to that point. OPERATION 1 2 Select an effect program for editing and press the e button to enable the Edit mode.
HINT 1 ■ When editing an effect, make sure that the Level or Mix parameters of the effect are set to relatively high values before adjusting any other parameters. Doing this ensures that any changes you make with the other Parameter Dials will be fairly noticeable. For information about each of the effects and their parameters, refer to the section EFFECTS AND PARAMETERS on page 20. ■ Compare Mode While editing an effect program, you can compare the sound of the newly edited program with the original one.
