User Guide for DigiTech SP-7 Stereo Phaser Pedal

Quick guide from the manual

The DigiTech SP-7 Stereo Phaser is a digital effect pedal. Because digital signal processors require constant power, 9-Volt alkaline batteries are recommended primarily for demonstration and practice. For optimal performance, use a compatible Harman power supply. If the LED brightness changes or the pedal fails to switch between Bypass and Effect, replace the battery or connect a power adapter.

Setup

Amplifier Setup: Connect your guitar to the pedal input and the pedal output to your amplifier. If using a single amplifier, use Input 1 (Mono) and Output 1 (Mono).

Effects Loop Setup: Connect the pedal between the Amp Send and Amp Return. If your amplifier's effects loop has a mix control, set it to 100% full wet.

Pedal interface

The pedal features several controls for shaping your sound:

• Speed Knob: Controls the LFO speed of the phaser effect. Clockwise increases speed.
• Depth Knob: Controls the intensity of the phaser effect. Clockwise creates a deeper sound.
• Modify Knob: Adjusts specific parameters depending on the selected phaser type.
• Type Knob: Selects one of the 7 available phaser types.
• Input/Output Jacks: Use Input 1 (Mono) for standard operation. Use Input 2 and Output 2 for true stereo operation.
• Foot Switch: Toggles the effect on/off and accesses Tap Tempo.

Stereo phaser types

• 2 Stage: Subtle phase effect with adjustable bias control.
• 4 Stage: Classic 4 Stage vintage phaser.
• Modern: Deep phaser with enhanced feedback and modulation.
• Boutique: Unique 6 Stage phaser with deep feedback control.
