EXTC STEREO
GUITAR EFFECTS REAMPER
The EXTC Stereo is a creative studio tool that gives you the ability to play any pre-recorded
audio track through stereo guitar eects pedals, using the process known as Reamping™ to
utilize your pedal collection in new and exciting ways.
The original single-channel EXTC is a secret weapon of mixing engineers worldwide, used
for adding guitar FX such as distortion pedals onto any audio track. With the EXTC Stereo,
you can also incorporate a lush stereo reverb pedal into your mix, play around with a ping
pong delay on vocals, or even add rotary eects for a unique element that helps your mix
stand out from the rest.
Connecting to your recording interface is made easy with both XLR and TRS options
available, along with front-panel jacks for your guitar pedals. Send & Receive level controls
optimize the signal path, while a Blend knob adjusts the wet/dry mix to ne-tune the results.
Features
• Stereo EFX loop to Reamp through any guitar pedals
• Send & Receive controls optimize signal path
• Blend control for precise wet/dry adjustment
• Transformer isolation to eliminate hum and buzz
Applications
• Use with stereo guitar eects on prerecorded tracks
• Take vocals, drums, or strings through eects pedals
for new and unique sonic combinations
• Can also be used for standard Reamping through
guitar ampliers
Extras
• Line-level i/o over both XLR and TRS connectors
• EFX on/o switch for A/B auditioning
• Phase invert to compensate for vintage pedals

The EXTC Stereo functions as the link between a
line-level recording interface and your instrument-level
guitar pedals. It converts the audio at each stage to the
proper impedance and signal level, making it easy to
incorporate guitar pedals into your mix without loss of
audio quality or tone.
Once connected, you can feed pre-recorded audio
tracks through any guitar pedal and easily record the
results directly back into your recording software, giving
you the ability to explore your creativity in the studio
while breathing new life into your pedal collection.
