This comprehensive guide walks you through the setup, recording, loop management, syncing, storage, and advanced features of the DigiTech JamMan Stereo, ensuring you get the most out of this incredibly versatile looper.
Overview: What is the JamMan Stereo?
The JamMan Stereo is a stompbox-style looper and phrase sampler that records in CD-quality 16-bit/44.1kHz stereo audio. It offers up to 35 minutes of onboard memory and supports up to 16 hours of recording time via SD card expansion.
Whether you’re using it to create live guitar loops, build vocal harmonies, or trigger backing tracks, the JamMan Stereo delivers rock-solid performance with tap-tempo, time-stretch, reverse playback, and USB connectivity for easy file management.
Unboxing and Setup
Inside the box, you’ll typically find:
JamMan Stereo Pedal
Power supply (9V DC, center-negative)
USB cable
Quick Start Guide and user manual
Powering Up
Connect the included power adapter to a wall outlet.
Plug the adapter into the DC input on the pedal’s side.
Power on. The display will show the current loop memory location.
⚠️ Tip: Avoid powering the unit via daisy-chained power supplies with other pedals. The JamMan requires adequate current (up to 1.3A) to function properly.
Input and Output Configuration
Inputs:
Left/Right ¼" instrument inputs (mono or stereo sources)
XLR mic input with phantom power switch (for vocal use)
Aux input (1/8" stereo mini-jack for MP3 players or phones)
Outputs:
Left/Right ¼" outputs (to amp, mixer, or audio interface)
Headphone out (1/8" jack for personal monitoring)
This stereo I/O flexibility makes the JamMan Stereo ideal for dual-instrument setups, vocals with guitar, or left-right signal routing for live rigs.
Looping Basics: Record, Overdub, and Stop
The JamMan’s footswitch layout is designed to keep looping fluid and performance-friendly.
Main Footswitch Functions:
Rec/Play/Overdub (Left Pedal):
First press: Record
Second press: Play
Third press: Overdub
Stop/Tempo (Right Pedal):
Tap to stop playback
Hold to delete loop
Double tap to activate tempo tap feature
This three-step loop building system makes it easy to start a loop, layer new parts, and stop precisely without missing a beat.
Loop Storage and Memory
The JamMan Stereo comes with 99 memory locations for saving loops. Each location can store loops or phrases complete with overdubs and settings.
Internal Memory:
Up to 35 minutes of stereo audio
Saved in proprietary .WAV format
Non-volatile: loops stay saved when power is off
Expandable Memory:
Supports SD cards up to 32GB
Adds over 16 hours of stereo recording time
Expands storage to up to 99 additional loops per card
⚠️ Note: Use only standard SD (not SDHC/XC) up to 32GB. Cards must be formatted within the JamMan.
Using the JamManager XT Software
To manage your loops on a computer:
Download JamManager XT software from DigiTech’s website.
Connect the JamMan Stereo via the included USB cable.
Launch JamManager XT and view saved loops.
Export or import .WAV files between your PC/Mac and the pedal.
This is especially useful for backing tracks, pre-recorded loops, or loop library organization.
Time Stretch and Tempo Sync
Tap Tempo:
Tap the Stop/Tempo footswitch twice to set a desired tempo.
Tempo is applied to the current loop’s playback (if time-stretch is enabled).
Time Stretching:
Loops can automatically stretch to match your tapped tempo without affecting pitch.
Useful for slowing down sections to practice or matching tempo live.
Loop Quantization and Auto-Record
The JamMan Stereo offers tools for seamless looping:
Auto Record Mode: Starts recording automatically when you play.
Quantize: Aligns your loop length to the beat—perfect for rhythm guitar or bass lines.
Rhythm Guide: Built-in metronome/drum pattern with adjustable tempo and time signatures.
This is particularly helpful for solo performers or musicians using loops in a live structured environment.
Advanced Loop Techniques
Loop Undo/Redo:
Press and hold Rec/Play/Overdub while overdubbing to undo the last layer.
Press again to redo the layer.
Loop Reverse:
With the loop playing, press Reverse to flip playback direction.
This is great for creating copyright effects or experimental textures.
Loop Copy:
Duplicate a loop from one memory slot to another using the Store and Select buttons.
Phrase Sampler Mode
In addition to live looping, the JamMan Stereo works as a phrase sampler.
Load pre-recorded audio (e.g., backing tracks, ambient pads, or DJ samples).
Assign each one to a different loop memory slot.
Use footswitches or external MIDI controller to trigger them during performance.
This is ideal for live looping DJs, vocalists, or performance artists who rely on triggered samples and loops.
External Control and MIDI Integration
To extend control, the JamMan Stereo supports:
FS3X footswitch (optional):
Provides hands-free access to functions like loop reverse, tempo increment, and loop scrolling.
MIDI Sync:
Use MIDI Clock to sync loops with drum machines, sequencers, or DAWs.
Great for locking loops to a band’s digital clock or live rig.
Live Performance Tips
Pre-load your setlist loops into specific memory locations.
Use quantize and metronome to keep timing tight.
Save your loops after creating them to avoid accidental deletion.
Combine live looping with phrase triggering for complex compositions.
Use the mic input to build vocal harmonies or beatbox loops on the fly.
