Knobs

TONE (RAMP)

With no ramping assigned, this is a tone control for the wobbly part of your sound only — it never touches your clean/dry signal. Straight up is neutral. Turn it right to thin out the bass and brighten; turn it left to darken and remove treble. When you're using the pedal's ramping feature, this same knob controls how long the ramp takes to happen.

tip: When dialing in chorus, keep coming back to this knob — TONE and MIX are very interactive and small moves here shape whether chorus sounds bright and glassy or dark and thick.

Adjusts the tone of only the wet (vibrato) signal path; noon is transparent, clockwise cuts low frequencies, counterclockwise cuts high frequencies. When a ramping dip switch or expression pedal is assigned, this knob instead sets the ramp time.

LAG

Turning this up nudges the wobbly signal slightly later than your dry signal, which is what makes chorus sound big and dimensional. The more you turn it up, the lusher — but also slightly noisier — it gets.

tip: For pure vibrato (MIX fully wet), keep LAG all the way counterclockwise so there's no delay between picking a note and hearing it, and for the quietest possible sound.

show text from manual

Sets the delay time (latency) between the wet and dry signal paths. Clockwise increases the delay for a lusher chorus but also adds slightly more noise to the wet path.

MIX

This decides how much effect you hear. Fully clockwise is pure vibrato (only the wobbly sound). Fully counterclockwise is basically your dry sound. Anywhere in the middle mixes the two, which is what creates chorus.

tip: Park it around noon for classic chorus, and tweak TONE at the same time — they work together to shape chorus character.

show text from manual

Blends the dry and wet signal paths, from 100% dry to 100% wet.

RPM

How fast the pitch wobbles. Left is slow and seasick, right is fast and fluttery. If you tap a tempo with the footswitch, that tap speed takes over from this knob.

tip: Slow RPM plus high DEPTH gives the signature warped-record droop; fast RPM with low DEPTH gives a shimmery Leslie-like flutter.

show text from manual

Controls the rate (speed) of the vibrato. Can be overridden by the tap tempo footswitch.

DEPTH

How far the pitch bends up and down. A little gives gentle warble; crank it clockwise for extreme, dramatic pitch-bending seasickness.

tip: When using an expression pedal to control the waveform directly (a 'whammy' effect), set DEPTH fully clockwise for the maximum pitch sweep.

show text from manual

Controls how wide the pitch modulation swings. HiFi has a wider range than previous versions.

WARP

This tilts the shape of the wobble so it's lopsided in one direction or the other. At noon the pitch rises and falls evenly. Turn it either way to make the wobble feel like it snaps one direction and drifts back the other — great for uneven, organic movement.

tip: Combine WARP with the two wave-shape toggles (the ModuShape engine) for unusual, jittery, or lurching motions you can't get from a normal vibrato.

show text from manual

Sets the center point / asymmetry of the modulation waveform. Counterclockwise makes the wave ramp up quickly and down gradually; clockwise makes it ramp up gradually and down quickly; noon is a perfectly symmetric wave.

Switches & toggles

LEFT WAVE SHAPE TOGGLE

Sets the shape of the first half of each wobble cycle. Sine is smooth and rounded, triangle is a bit more angular, square jumps abruptly between pitches.

tip: Mixing a smooth shape on one half with a square shape on the other (using the right toggle) creates stutter-and-glide hybrid waves that feel truly warped.

show text from manual

Selects the shape of the first half of the modulation waveform: left = sine, middle = triangle, right = square.

RIGHT WAVE SHAPE TOGGLE

Sets the shape of the second half of each wobble cycle. Note it's reversed from the left toggle — here square is on the left and sine is on the right. Combining the two toggles lets you design custom wave shapes for the pitch movement.

tip: Set left to sine and right to sine (both smooth) for classic vibrato; introduce square on either side for choppy, glitchy movement.

show text from manual

Selects the shape of the second half of the modulation waveform: left = square, middle = triangle, right = sine. Together with DEPTH and the left toggle it forms the ModuShape engine.

1/2/4 (3/6/8) (R/-/+) TOGGLE

In normal use this decides how the pedal divides up the tempo you tap in — letting the wobble run at the tapped speed, or twice or four times as fast. Flip a rear dip switch and this same toggle instead controls the 'hold' behavior of the left footswitch: 'R' for ramp, '-' to momentarily kill the vibrato while you hold the switch, '+' to momentarily add it.

tip: Leave it on a straightforward division at first. Only dig into the R/-/+ meanings once you've enabled Hold mode via the rear dip switch.

show text from manual

A three-position toggle that sets the tap-tempo subdivision (1, 2, or 4 — or 3, 6, 8 if the rear tap-division dip switch is set to '3'). When the rear Hold dip switch is on, it instead selects R/-/+ hold functions. Divisions are 2x slower when applied to ramping.

LOWER TOGGLE (Preset selector)

This is your preset switch. Middle means 'use whatever the knobs are physically set to right now.' Flip left or right to instantly jump to a saved sound. If you turn a knob after recalling a preset, the little light dims to warn you the preset has been changed but not re-saved.

tip: To save the RIGHT preset: hold the right (bypass) footswitch 3 seconds, then hold both footswitches together 3 seconds until the LED blinks. For the LEFT preset, start by holding the left (tap) footswitch instead.

show text from manual

Recalls presets. Right position recalls one saved preset, left recalls another, middle reflects the current live knob/switch/dip positions. The LED above it dims when a recalled preset has been altered.

Footswitches

BYPASS Footswitch

The on/off stomp for the effect. It's true bypass, so when off your signal passes through completely clean and untouched. You can make it momentary — active only while your foot holds it down — using a rear dip switch.

tip: Also used in the preset-saving sequence (hold it 3 seconds to begin saving the right preset slot).

show text from manual

Activates or bypasses the effect using a true-bypass relay. Can be set to momentary (only on while held) via the MoToByp rear dip switch.

TAP/HOLD Footswitch

Tap it in rhythm to set the wobble speed by ear. If you've turned on Hold mode via the rear dip switch, holding this footswitch instead triggers a ramp, or momentarily stops/starts the wobble depending on the front toggle position.

tip: It always follows your last two taps, so you can update the tempo on the fly mid-song with a couple of stomps.

show text from manual

In normal mode, sets tap tempo (honors the last two taps). In Hold mode (enabled by rear dip switch), holding it triggers ramping, or momentarily deactivates the LFO ('-' toggle position) or momentarily activates it ('+' position).

Display & indicators

Preset/Status LED

The little light that tells you what's going on: it shows the effect is on, blinks when you successfully save a preset, and goes dim to warn you that you've changed a preset without re-saving it.

tip: If the light is dim after recalling a preset, you've moved something — save again if you want to keep the change.

show text from manual

Indicates effect on/off status, blinks to confirm preset saves, and dims above the lower toggle to show a recalled preset has been modified.

Side panels

Switches & toggles

Left dip-switch bank (Lag, Mix, RPM, Depth, Warp, Bounce, Hold, MoToByp)

This bank of tiny switches assigns which knobs the ramp/expression system can move (turn a parameter's switch on to include it), and flips several behavior modes: Bounce for back-and-forth motion versus one-way-and-stay, Hold to unlock the footswitch's hold tricks, and MoToByp to make bypass momentary.

tip: Ignore these entirely until you're comfortable with the basic sound — Chase Bliss recommends it. Remember: ramping always resets when you bypass the pedal.

show text from manual

Eight dip switches. Lag/Mix/RPM/Depth/Warp turn each parameter on or off for ramping or expression/CV control. Bounce makes ramped parameters modulate back and forth (on) versus ramp-and-hold (off). Hold enables the Hold mode for the tap footswitch and the R/-/+ toggle functions. MoToByp makes the bypass footswitch momentary.

Right dip-switch bank (Lag, Mix, RPM, Depth, Warp, Control, Division, Sweep)

This bank fine-tunes how the assigned parameters move: which direction they travel (up or down), whether your tap sets the wobble speed or the ramp speed, whether extra tap subdivisions are available, and whether a sweep runs from the current knob setting up to full or down to zero.

tip: Use Sweep together with a knob's physical position to precisely limit an expression pedal's range — e.g. set MIX at noon and Sweep to Top to sweep from a set amount of chorus up to full wet.

show text from manual

Eight dip switches. Lag/Mix/RPM/Depth/Warp set whether each assigned parameter rises (clockwise) or falls (counterclockwise) when ramped, and how it responds to expression. Control (Tap Control) sets tap to dictate RPM rate ('P') or Ramp rate ('R'). Division enables 3/6/8 tap subdivisions and MIDI note divisions when set to '3'. Sweep sets whether ramp/expression moves between the knob position and maximum ('T', top) or minimum ('B', bottom).

Jacks & connectors

IN

Where your guitar (or the pedal before it) plugs in.

show text from manual

1/4-inch mono input jack. Input impedance is 1M ohm.

OUT

Where you connect to your amp or the next pedal in line.

show text from manual

1/4-inch mono output jack. Output impedance is less than 1k ohm.

EXP / CV

Plug in an expression pedal here to sweep parameters with your foot, or feed it control voltage from other gear. With no parameter selected on the dip switches, it directly controls the waveform for a 'whammy'-style pitch sweep. Which parameter it controls, and its range, are set with the rear dip switches and the knob positions.

tip: To set the sweep range, position the target knob where you want the sweep to end and use the 'Sweep' dip switch (Top = sweeps up to max, Bottom = sweeps down to min).

show text from manual

1/4-inch TRS jack for an expression pedal (parameter assigned via rear dip switch; tip goes to wiper) or 0–5V control voltage on the tip (ring left floating). Plugging anything in automatically switches assigned parameters from ramping to expression/CV control.

TAP / MIDI

Lets you send or receive tap tempo with another pedal using an ordinary cable, or connect a MIDI adapter box for full MIDI control of the pedal.

tip: See Chase Bliss's separate MIDI manual for the full range of MIDI features this jack unlocks.

show text from manual

1/4-inch TRS jack usable as a tap-tempo input or output with a regular instrument cable, or to interface with an Empress Effects Midibox for MIDI control.
