Twin Peaks is a tremolo that consists of two separate analog audio paths
whose volume can be modulated.
One is a low-pass and the other a high-pass filter.
When you modulate both in sync it sounds like a regular tremolo where
the whole audio spectrum is modulated at once.
When you modulate them out of sync your output signal will pan from
the low pass to the high pass signal and you will get interesting phasing
effects where the two filter curves meet.
This is what is usually referred to as a harmonic tremolo.
While the Tap tempo and LFO functions are digital, the audio path is 100%
analog. The tremolo effect is achieved using optocouplers.
There are 4 tremolo modes:
V : Volume modulation, your classic tremolo
F : Frequency modulation, harmonic tremolo
B : Bass modulation only, with fixed treble
T : Treble modulation only, with fixed bass
The LFO has 8 available modulation shapes:
Sawtooth, Reversed Sawtooth, Square, Triangle, Sine, Hypertriangle,
Reverse Hypertriangle, Random Levels
New in V5 is the envelope control of the rate. This allows you to dynami-
cally control the rate with your playing intensity.
Power Supply:
The power supply needs to be 9V/100mA center negative like the
common BOSS power supplies:
Make sure the polarity of your power supply is correct or it will damage
the pedal. Do NOT run at higher voltages.
As the pedal uses a digital processor operating at high frequencies, you
may hear some high pitched noise if you use it together on the same
power supply with other pedals (daisy chained) even when it is bypassed.
The noise can bleed through the power supply into the other pedal’s
signal. This is normal for such devices. It might not be the case in your
particular setup but if you notice that, I would suggest using an isolated
power supply.
