Electro-Harmonix Slap-Back Echo User manual

Congratulations on your purchase of the Slap-Back Echo delay pedal! The Slap-Back

Echo is a modern day update of the rare and classic Electro-Harmonix Slap-

Back Echo from 1978. A Gain knob, Blend knob, and Time switch allow you to

tailor the Slap-Back’s all-analog echo to enhance your tone from subtle

doubling to intense bathtub reections. The compact size allows it to easily

squeeze onto crowded pedalboards.

Analog Echo

POWER SUPPY REQUIREMENTS:

Voltage: 9VDC Current: 15mA Polarity: Center-Negative

This device comes equipped with an Electro-Harmonix 9.6DC-200 power supply. Use of the wrong adapter

Controls and Connections

1. GAIN Knob The GAIN knob boosts your dry signal before it hits the

BLEND knob and echo circuitry. As you turn GAIN clockwise, your signal

gets louder. The GAIN knob increases your signal level by up to 20dB,

which is handy for added volume during solos and important riffs.

2. BLEND Knob The BLEND knob controls the wet/dry mix at the

output jack. With the knob fully counterclockwise, the signal is 100%

dry. Set the knob fully clockwise and your output is all echo. Please

note: the dry and wet signals are both boosted by the GAIN knob.

The output signal is boosted even with BLEND set to 100% dry.

3. TIME Switch The TIME switch allows you to select between three

different delay times:

UP: 100ms

MIDDLE: 65ms

DOWN: 45ms

4. FOOTSWITCH and STATUS LED The footswitch engages or bypasses

the effect. The Status LED lights when the effect is engaged. The LED

is off in bypass mode. The Slap-Back Echo employs True Bypass.

5. INPUT Jack Audio input to the Slap-Back Echo.

6. AMP Jack Audio output from the Slap-Back Echo. In bypass mode,

the AMP jack is directly connected to the INPUT jack and nothing else.

7. 9V Power Jack Attach the output plug from the included power

supply to the 9V power jack. The Slap-Back Echo draws 15mA at 9VDC

on a center-negative plug. Do not exceed 10.5VDC on the power jack.

Operating Instructions

Connect your guitar to the INPUT jack on the Slap-Back Echo and the

AMP jack to your amp’s input. Plug in the included power supply and

insert its output plug into the power jack. Press the footswitch to

ensure the Status LED is lit. Your Slap-Back Echo is now ready to go.

For a quick starter setting, set the controls to the following:

GAIN: 9 o’clock BLEND: 11 o’clock

TIME: Upper position
