6.2.3 Combinations of effect algorithms

(multi-effects programs)

PHASER & DELAY: Phaser and delay combined.
FLANGER & DELAY: Here the input signal is delayed and

processed with a pronounced wave-like effect. It is particularly

effective for highlighting single notes, but can also be used to

make solos more interesting.

CHORUS & DELAY: This algorithm combines signal delay with

the popular chorus effect.

CHORUS & COMP: Incredible sustain effects can be produced

with the compressor. This is especially useful for sustaining

individual guitar notes. Combined with chorus, it can make the

audio signal extremely dense.

6.2.4 Special effects

COMPRESSOR: A compressor limits the dynamic range of the

audio material, thus producing audible and creative sound effects.

Pronounced use of the compressor (using the EFFECTS control)

allows you to compress the overall dynamic range of the material.

AUTO WAH: The legendary wah-wah effect owes its fame

mainly to Jimi Hendrix. Describing it is certainly more difficult than

simply listening to Hendrix using it on Voodoo Chile. In American

funk music of the ’70s you can hear auto-wah effects used in a

variety of applications. The auto-wah alters its filter frequency

automatically depending on the signal’s magnitude, rather than

being controlled by the position of a pedal.

TREMOLO: Simulates the classic Fender Tremolo. It has

returned to popularity with trip-hop.

ROTARY: This is the quintessential simulation of the classic

organ effect normally produced by speakers rotating at slow or

fast speed in an extremely heavy speaker cabinet. This effect

uses the physical principle of the Doppler effect to modulate the

sound.

NOISE GATE: Noise gates are used to remove or reduce

noise or other interference. Guitar signals in particular are very

sensitive to interference. Not only do guitarists often use high-

gain settings but guitar pick-ups can amplify unwanted inter-

ference. This can be painfully apparent during breaks in the

music. And how does a noise gate work? It simply mutes the

signal during breaks, eliminating any interference at the same

time.

6.3 The separate reverb effect

The reverb effect is independent of the multi-effects processor

and can be added to the mix signal at any time. To edit the

REVERB function, press button D in EDIT mode (pressing the

two arrow buttons simultaneously) and use the two arrow

buttons to select one of the nine different reverb types available:

1

Tiny Room

2

Small Room

3

Medium Room

4

Large Room

6

Small Spring

7

Medium Spring

8

Short Ambience

9

Long Ambience

Simulates the early reflections of a

reverbless room

7. TUNER

Press the TUNER button to activate the built-in tuner.

7.1 Tuning your guitar

The chromatic tuner automatically recognizes the frequencies

of all the standard guitar notes. For the A-string this means a

frequency of 220 Hz. When you plug your guitar into the

device and play an open string, the tuner will recognize and

display the note. Since the tuner uses an auto-chromatic scale,

it can also recognize semi-tones, which are shown with a “b” in

the display.

It may happen, however, that a note is displayed as “A” but is

actually slightly out of tune. This is shown by at least one of the

four LEDs at the foot of the display lighting up. In certain cases

even two of the LEDs may light up, which indicates that the pitch

of the note played lies between the pitches represented by the

two LEDs. When the circular tuner LED in the middle lights up,

this means the note played is in tune.

7.2 Setting reference pitch “A”

To give you maximum freedom for tuning your guitar, you can

change the preset reference pitch “A”. For clarity’s sake, let’s

look at this in more detail.

The so-called concert pitch “A” has been raised steadily over

time. For example, the tuning forks used by Bach, Händel or

Mozart were 415, 420 or 421 Hz (oscillations per second). Today’s

orchestras tune to “A” at 444 Hz, and the Berlin Philharmonic

Orchestra lead the field with their own concert pitch “A” at

447 Hz.

The reference “A” on your V-AMPIRE has been factory-

programmed at 440 Hz. If you are going to play with a big orchestra

tuning their instruments to a reference pitch of 444 Hz, you will

need a function that allows you to change your reference pitch.

To activate this function, switch on the tuner by pressing the

TUNER button and switch to EDIT mode by pressing the two

arrow buttons simultaneously. The display will show “40”, which

means 440 Hz. Use the arrow buttons to raise or lower the

reference pitch by up to 15 Hz. The display always shows the

last two digits as the first digit is always 4. For example, if you

start with a reference pitch of 440 Hz and press the right-hand

arrow three times, the display will read 43, i.e. 443 Hz. To quit

EDIT mode, press either the TUNER or the TAP button. Any

changes will be stored automatically. The tones for the other

strings on your guitar will automatically be adjusted to the new

reference pitch.
