INTENSITY (pot) 1
Controls the depth and the character of the chorus (vibe) or vibrato sound and it defines the strength and dynamic of the pulsing nature of the effect. A more pronounced pulsing feel starts
from around the 2 o’clock position and onwards. The contour of the intensity knob is custom designed to enable a quick and easy set up of different vibe sounds.
SPEED (pot) 2
The speed knob adjusts the speed pulsations of the vibe (chorus) or vibrato sound. Its size and placement also makes foot control possible.
VOLUME (side trimmer) 3
This trimmer adjusts the level of the output signal. At minimal setting the volume is reduced by 4dB, and the maximum setting gives a slight boost to input signal. So find your preferred effect
volume and leave it. In bypass this trimmer has no effect. To set it please use a small plastic screwdriver.
VIBRATO/CHORUS (switch) 4
This toggle switch selects between the classic vibe/chorus sound and the vibrato sound, a very under used part of vibe pedals, this effect can give a great sense of movement when used in
the right way.
BRIGHT/ORIGINAL (switch) 5
Original Uni-Vibe pedals had relatively low input impedance and a warm tone, so for that vintage “Vibe” set the switch to the “ORIGINAL” position. For a brighter tone flip the switch up to
the “BRIGHT” position, this setting turns on the input FET buffer. If the Vibe Machine is the first (or only pedal) in your effect chain this setting will use the entire tonal range of your pickups.
If any other pedal with a similar buffer is placed before the Vibe Machine the BRIGHT/ORIGINAL switch will have no effect.
PEDAL+ (expression pedal jack) 6
For external speed control you can use an expression pedal. Vibe Machine V-1s from serial No. #703 onwards will work with all expression pedals (TRS) with a linear pot (tip to wiper). You can use any expression pedal that has a 5k, 10k, 25k, 50k, 100k or 250k linear pot. Also, you can calibrate the Vibe Machine to work with a specific expression pedal if your expression pedal doesn’t have full speed range from 0% to 100%. This calibration is not necessary if your expression pedal has full resistance range but this instruction is here for such expression pedals that don’t have full resistance range. Please see the wiring diagram on page 2 of this manual. Also, please see additional info about expression pedal models in our FAQ section at drybell.com.
