SLAMMI

POLYPHONIC PITCH-SHIFTER/HARMONY PEDAL

Congratulations on your purchase of the Electro-Harmonix Slammi, a foot controlled

polyphonic pitch-shifter/harmony pedal. The Slammi smoothly sweeps the pitch of

the guitar signal either up or down without using any moving parts, it does not use a

potentiometer, optics or magnetism. The result is a responsive pedal that allows

precise control over a clean, glitch free, polyphonic pitch-shifting algorithm. To top it

off the Slammi can create harmonized intervals by mixing your dry signal with the

effect using the adjustable DRY VOL control.

GETTING STARTED

Plug your guitar into the INPUT jack; connect your amp to the OUTPUT jack. Tilt the

Slammi forward to light the EHX logo in the center of the pedal. Your Slammi is ready

to go! Please note: as long as a plug is inserted into the INPUT jack, a drain is

placed on the 9V battery inside the Slammi. It is recommended that you disconnect

the INPUT jack when the Slammi is not in use to extend battery life.

MAX BEND Control

The Max Bend control, located on the input side of the Slammi, acts as an 11-way

switch selecting the maximum bend or maximum interval of chromatic transposition.

The chart below shows where each maximum bend setting is located on the

thumbwheel, the odd numbers are not actually on the control:

BEND Push Button

The Bend button, next to the MAX BEND thumbwheel, selects whether the pitch is

shifted up or down relative to the original pitch. If the button is out, the pitch will be

shifted UP; likewise if the button is in, the pitch is shifted DOWN.

DRY VOL Control

The Dry Volume (DRY VOL) thumbwheel, next to the INPUT jack, controls the volume

of your dry signal, mixing it with the effect signal. This enables you to harmonize with

your original pitch while at a fixed interval or when you bend notes. A detuned effect

can be made when MAX BEND is set to 0 and DRY VOL is above 0.

CALIBRATION

To ensure the Slammi responds to its full sweep range, it may be necessary to

calibrate the sweep of the Slammi when it is used on a different surface since its last

use. It is particularly important to calibrate if the Slammi is used on a slanted surface.

We recommend calibrating the Slammi after unwrapping it from its packaging, during

your first use of the pedal. The Slammi is unique compared to other Next Step

pedals in that it can be calibrated so maximum effect is either in the toe-down

position or heel-down position, allowing you to reverse the pedal’s sweep direction.

CALIBRATION PROCEDURE – TOE POSITION = MAX BEND (factory default)

1. Place the pedal on the surface where it will be used.

2. Ensure the Slammi pedal is sitting flat on the surface then press and release

the CALIBRATE button once; the EHX logo begins to blink indicating the toe

position has been saved.

3. While the EHX logo continues to blink, rock the pedal all the way back to the

extreme heel position and hold it there.

4. Press and release the CALIBRATE button once more.

5. The EHX logo will stop blinking to indicate the heel position has been saved.

CALIBRATION PROCEDURE – HEEL POSITION = MAX BEND

1. Place the pedal on the surface where it will be used.

2. Rotate the Slammi back to the heel position and hold it there while you

press and release the CALIBRATE button once; the EHX logo begins to blink

indicating the heel position has been saved.

3. While the EHX logo blinks, tilt the pedal forward to the toe position allowing

the pedal to sit flat on the surface.

4. Press and release the CALIBRATE button once more.

5. The EHX logo will stop blinking to indicate the toe position has been saved.

If you accidentally press the CALIBRATE button and the EHX logo blinks, do not press

CALIBRATE again. After approximately 7 seconds, the Slammi will stop blinking and

ignore the button press.

Please Note: to reduce the total sweep range of the Slammi, when calibrating,

move the Slammi up a little when pressing the button to save the toe position or

move the Slammi forward a bit when pressing the button to save the heel position.

DRY VOL Control The Dry Volume (DRY VOL) thumbwheel, next to the INPUT jack, controls the volume of your dry signal, mixing it with the effect signal. This enables you to harmonize with your original pitch while at a fixed interval or when you bend notes. A detuned effect can be made when MAX BEND is set to 0 and DRY VOL is above 0.

ENTERING/EXITING BYPASS Switch between buffered bypass and effect mode by tipping the Slammi forward, in the toe direction, past the flat position of the Slammi. You do not need to tip the Slammi all the way forward; 25% of the total forward travel will do it. The Slammi needs to return to its flat position before you can switch between bypass and effect mode again. When the Slammi is in effect mode, the EHX logo in the center of the pedal will light up. In bypass mode, the logo does not light.
