Chapter 1 Playing Sounds What is a Patch? Numbers When performing on your bass, you may select a variety of different tones according to what and where you are playing. The effects you want to use and the parameter settings (knob positions) will vary depending on the tone. You can store combinations, or “sets,” of volume level and other of these parameter settings, and by using the pedals to switch these sets, you can change tones instantly. Each of these stored sets is called a “patch.
Chapter 1 Playing Sounds You can use pedals 1–4 to switch on and off the individual effects that are used in a patch. Each pedal shows the names of two effects; the effect that you are currently able to switch on and off is indicated in the lower row of the right display. You can also change these with [PEDAL ASSIGN] (p. 45). Turning Off the Power 1. Before turning off the power, confirm the following.
Chapter 2 Creating You Own Favorite Tones (Patches) Getting the Tones You WantFast (EZ Tone) Adjusting the Tones with the Knobs In addition to tones (patches) that you can actually use in performances, the GT-6B also features internal sample settings that are very useful when you want to create such tones on your own. This feature is called “EZ Tone.” The GT-6B panel features fifteen knob controls. These knobs let you make changes to the selected patch’s tone quickly and easily.

Chapter 4 The Effects Explained This chapter describes the particular qualities of each of the GT-6B’s internal effects, as well as the parameters used to control them. Rack 160D Models the dbx 160x. Vtg Rack U Models the UREI 1178. Attack The sound that is input to each effect is called the “direct sound,” and the sound modified by the effect is called the “effect sound.
Chapter 4 The Effects Explained OD/DIST (Overdrive/Distortion) This effect distorts the sound to create long sustain. The GT6B provides nine types of distortion with two different custom settings. ■ OD: Overdrive This provides the warm, natural type of distortion that occurs naturally when you turn up the volume on a tube amp. This effect is often used as an amp pre-booster. ■ DST: Distortion This effect features a deep, powerful distortion that is difficult to achieve with amp distortion alone.
Chapter 4 The Effects Explained CHORUS Pre Delay This is an effect that adds a slightly detuned sound to the original bass sound, resulting in a beautiful sound with greater depth and breadth. Developed by BOSS, this is one effect that is popular the world over. Low Cut * When the Bypass EXP Mode (p. 55) and Noise Suppressor (p. 44) is set to “Off” and only CHORUS or REV/DLY is used, the direct sound is output as analog output.
Chapter 4 The Effects Explained * When Sound On Sound is selected, Pedal 4 and the BYPASS/ CTL pedal function as Sound On Sound controls. For more detailed information, refer to “Using Sound On Sound” (p. 54). ■ REV: Reverb Parameter Value Type Reverb Time Pre Delay Low Cut Room1, Room2, Hall1, Hall2, Plate 0.1 s–10.0 s (0.1 s step) 0 ms–10 0ms (1 ms step) Flat, 55.0 Hz, 110 Hz, 165 Hz, 200 Hz, 280 Hz, 340 Hz, 400 Hz, 500 Hz, 630 Hz, 800 Hz 700 Hz, 1.00 kHz, 1.40 kHz, 2.00 kHz, 3.00 kHz, 4.00 kHz, 6.
Chapter 4 The Effects Explained Delay Time Fine Tempo Makes fine adjustments (in units of 1 ms) to the delay time. This sets the tempo that determines the length of the loop. The CTL pedal indicator flashes at the rate set here. When this is set to “BPM,” you can set the tempo with the Number 4 pedal (tap input). Tap Time (Used Only with Pan) Adjusts the delay time of the right channel delay.
Chapter 4 The Effects Explained Treble Adjusts the tone of the upper range. ● When Type is Set to CONCERT 810 Bright Off, On Middle Turns the bright setting on/off. Turn this on to make the sound brighter. Adjusts the tone of the midrange. * While some amps do not feature a middle control, this control still functions even when simulating such amps. If you want to recreate the sound as output by the original amp, set Middle to “0.
Chapter 4 The Effects Explained Direct Level Level Adjusts the volume of the direct sound. Adjusts the overall volume level of the 3-band equalizer. The volume level is boosted more as the knob is turned further to the right of center; turning the knob to the left of the center position cuts those frequencies. 3 BAND PARAMETRIC EQ This is a 3-band parametric equalizer allowing EQ for the lower range, midrange, and upper range.
Chapter 4 The Effects Explained ● When Type is Set to Custom 1–3 Down: You can make settings for the following parameters when TYPE is set to Custom 1–3. The filter falls from higher to lower frequencies in response to the input level. Sens Making “Custom” Pedal Wah Settings (p. 53) Parameter Value Type (1–3) Q (1–3) Range Low (1–3) Range High (1–3) Presence (1–3) CRY WAH, VO WAH, Bass WAH -50–+50 -50–+50 -50–+50 -50–+50 Pdl Position (Pedal Position) This adjusts the position of the wah pedal.
Chapter 4 The Effects Explained Rate This selects the auto wah cycle. * When set to BPM, the value of each parameter is set according to the value of the Master BPM (p. 44) specified for each patch. This makes it easy to achieve effect sound settings that match the tempo of the song (synchronizing the cycle to one-half or one-fourth of the BPM when the set cycle rate is increased). When setting to the BPM, press PARAMETER [ ] to display the Master BPM settings screen.
Chapter 4 The Effects Explained Sens Depth This adjusts the Enhancer sensitivity. The more the value is increased, the more softly you can play and still have the effect applied. This controls the ratio of harmonics. Raising the value increases the harmonic components, resulting in a unique and different tone. Freq (Frequency) Level Sets the frequency range for the enhanced sound. Adjusts the volume. Mix Level Adjusts the amount of enhanced sound added to the mix. ■ R.
Chapter 4 The Effects Explained FX-2 12Stage: This is a twelve-stage phaser. This produces a phase effect with greater depth. Bi-Phase: This is a phaser effect in which two phase shift circuits are connected in series. Rate This sets the rate of the phaser effect. * When set to BPM, the value of each parameter is set according to the value of the Master BPM (p. 44) specified for each patch.
Chapter 4 The Effects Explained ■ FL: Flanger ■ HRM: Harmonist This produces a flanging effect that gives a sort of “twisting” character to the sound. Although it resembles the phaser effect, the flanger yields a colder, more metallic twisting effect. This effect adjusts the shift in pitch according to an analysis of the pitch of the bass input, allowing you to create harmonics based on Diatonic or user definable scales.
Chapter 4 The Effects Explained Feedback This adjusts the feedback amount of the harmonist sound. * Only PS1 can be selected when this is set to 2-Mono or 2Stereo. 5. Press PARAMETER [ ][ ] to move the cursor, then rotate the PATCH/VALUE dial to set the User scale. Scale You can switch the number of the user scale. Level DIR (Direct) This adjusts the volume of the harmonist sound. Sets the note name of the input sound. Key This specifies the key of the song you are playing.
Chapter 4 The Effects Explained Mono: Pitch Min This mode is for the input of individual notes. Select this setting when you want to obtain a pedal bend effect using an external expression pedal. This sets the pitch at the point where the expression pedal is fully lifted. * Because of the need to analyze the pitch, chords (two or more sounds played simultaneously) cannot be played. Pitch Adjusts the amount of pitch shift (the amount the pitch changes) in semitone steps.
Chapter 4 The Effects Explained Lo PreDly (Low Pre Delay) Parameter Value Adjusts the time from when the direct sound in the lower range is output until the effect sound is output. Extending the pre-delay produces the sensation of multiple sounds being played (doubling effect). Step Pitch 1–17 -24 – +24 Length Sound Attack , , , , , Mute, Stacc, Full Less, Thumb, Pluck Lo Level (Low Level) , Adjusts the volume of the lower range. “Creating Original Phrases (User Phrase)” (p.
Chapter 4 The Effects Explained 4. Press PARAMETER [ ] a number of times until the User Phrase settings screen is displayed. Attack Specifies that the note is to be played with an attack. fig.04-04 Less: The note is played with no attack. Good for hammering and other such techniques. Thumb: 5. Press PARAMETER [ ][ ] to move the cursor, then rotate the PATCH/VALUE dial to set the User phrase. fig.04-50 Step The note is played with the sound as if the string is struck with the thumb.
Chapter 4 The Effects Explained ■ VIB: Vibrato Mode The vibrato effect is created by slightly modulating the pitch. This sets the mode used to switch the vowels. Parameter Value Rate Depth Trigger Rise Time 0–100, BPM 0–100 Off, On 0–100 1 Shot: –BPM The tone changes from Vowel 1 to Vowel 2 one time only as the strings are played. The time required for the change is adjusted with the Rate setting. Auto: The change in tone between the two vowels (Vowel 1 and Vowel 2) is repeated.
Chapter 4 The Effects Explained Manual ■ SYN: Bass Synth (with Auto) Sets the point at which the two vowels will be switched. When set to “50,” an equal length of time is used to switch Vowel 1 and Vowel 2. When it is set to lower than “50,” the time for Vowel 1 is shorter. When it is set to higher than “50,” the time for Vowel 1 is longer. This effect produces a synth bass sound. Two methods are used, the “Internal Sound Generator method” and the “Waveform Shaping method.
Chapter 4 The Effects Explained Bow: Waveform shaping outputs a soft sound with no attack. Octave Shift (with Square and Saw) This outputs sound one octave below the original sound. PWM Rate (Pulse Width Modulation Rate) (with Square) Modulation is applied to the waveform (Square wave only) to create a broader, fatter sound. Higher values increase the rate of the modulation. PWM Depth (Pulse Width Modulation Depth) Resonance This adjusts the filter resonance (the amount of feedback).
Chapter 4 The Effects Explained NS: Noise Suppressor This effect reduces the noise and hum picked up by the bass. Use this when noise that occurs when you are not playing the bass becomes noticeable. Since it suppresses the noise by monitoring the volume level of the actual bass sound being input, it always gives a natural effect. Parameter Value On/Off Threshold Release Off, On 0–100 0–100 On/Off (Effect On/Off) This parameter turns the noise suppressor on/off.
