Chase Bliss Gravitas Tremolo is an analog tremolo pedal with
unprecedented amount of control features. The signal path of the
Gravitas Tremolo is 100% analog. Each control is attached to a
microprocessor which controls the analog effect circuitry. Your guitar
signal will not be digitized inside the pedal. Digital controls make it
possible to have features that have not been possible before with analog
- Controls and connections:
Drive (Ramp): In basic settings this control acts a the gain control for the effect. When one or more dip switches behind the pedal are in the "On" position this control adjusts one or several of the following parameters: volume, mix, rate, depth, form. Each of these can be set to modulate, rise or fall.
Volume: Sets output volume level. It is recommended to set this control always to 5 o'clock and fine-tune the volume level with the Gain control. This control can also be controlled with an expression pedal or Drive (Ramp) control.
Tone: Sets the tonal color of the effect with a wide range. At 12 o'clock it doesn't color your tone. Towards 5 o'clock the sound gets brighter and towards 7 o'clock it gets darker.
RPM: Sets effect speed. A lot of range from very slow to very fast. This control can be overriden with the tap tempo footswitch.
Depth: Controls the range of the phase effect. At 5 o'clock you will get the strongest phasing.
Sway: This control controls the modulation's middle part. At about 7 o'clock the modulation rises quickly and falls gradually. Towards 5 o'clock the rise is slower and the fall is quicker. At 12 o'clock you will get a perfectly symmetrical waveform.
1-2-4 (3-6-8) (S-B-H) switch: Sets the tap tempo subdivision. Turning the tap tempo dip switch behind the pedal to "On" position you will get options 3-6-8. You can also set the tempo for RPM or Ramping features depending on how you have the dip switches set. If the Mode dipswitch is set to "On", this control will allow you to choose the tremolo type. S = Standard, H = Harmonic, B = Both at the same time.
Left waveform switch: Sets the waveform for the first half of the modulation cycle. Options are sine, triangle and square.
Right waveform switch: Sets the waveform for the latter half of the modulation cycle. Options are sine, triangle and square.
Expression pedal / CV input: Volume, Mix, RPM Depth and Warp can be controlled with an expression pedal. 1/4" TRS input. Can also be controlled with 0-5V control voltage.
Tap/MIDI: Can be used as a tap input or output with a regular 1/4" instrument cable.
- Power Requirements: 2,1mm 9-18V DC centre negative power supply or 9V battery. 20 mA. 18V gives you more volume and headroom.
- True Bypass (very silent switch)
- Made in USA
