Siegmund Doppler Vibe Instructions
Your guitar can be plugged in straight into the effect and the outputs connected to one or two amplifiers or any device with
high impedance input.
A clean boost or overdrive pedal after the guitar and before the effect gives the oscillator a stronger signal to work with
.
The Doppler Vibe works well with amps that have a Series FX loop placed between the preamp and power amp.
With two amps the STEREO output can be connected to the second amp’s return jack or in front of the amp.
With a Parallel FX loop the Mix knob of the amp and the INTENSITY knob of the effect are balanced for the desired sound.
Signal Processing
The signal at the input goes into the TONE control and allows the player to boost the brighter or darker side of the Doppler
shift frequency spectrum, which is neutral in the center setting.
The BALANCE control combines both frequency ranges for the Mono output mode and allows balancing the output volume
of each side of the Doppler effect.
Both TONE and BALANCE emphasize either side of the Doppler effect, making the overall tone brighter or darker.
By turning them in opposite directions, the effect remains in balance, giving a true Doppler pitch shift vibrato.
Emphasizing one side with both knobs shifts the effect balance and gives more of a tremolo in the selected frequency range.
The INTENSITY knob controls the strength of the vibrato, pulsing both Doppler frequency sides alternately.
Output volume increases with higher settings. A stronger input signal allows higher settings without cutting off the signal
between the pulses.
The SPEED knob controls the rate of the pulse and the FAST/SLOW toggle switch gives a slower or faster sweep range.
The LED pulses with the vibrato speed.
