Mode 1
Normal, Direct Mix,
Switches the SEND/RETURN 1 mode.
Branch Out
Normal
Outputs the input to LOOP to the SEND 1 jack and the input from
the RETURN 1 jack to the circuit post-LOOP.
Use this when you want to connect an external effects device serially
in the GT-PRO's effects chain.
Direct Mix
Outputs the input to LOOP to the SEND 1 jack, mixes the input from
the RETURN 1 jack with the input to LOOP (the direct sound), then
outputs this to the circuit post-LOOP. Use this when you want to mix
the GT-PRO's effects sounds together with the sound with the exter-
nal effects device applied to it.
Branch Out
outputs the input to LOOP to the SEND 1 jack. The input from the
RETURN 1 jack is disregarded. For example, using this with the GT-
PRO's reverb and delay immediately ahead of the loop allows you to
use the SEND 1 jack as a direct out.
Send 1 Level
Adjusts the volume of the output to the ex-
0–200
ternal effects device.
Return 1 Level
Adjusts the volume of the input from the ex-
0–200

the RETURN 2 jack to the circuit post-LOOP.
Use this when you want to connect an external effects device serially
in the GT-PRO's effects chain.

the RETURN 2 jack with the input to LOOP (the direct sound), then
outputs this to the circuit post-LOOP. Use this when you want to mix
the GT-PRO's effects sounds together with the sound with the exter-
nal effects device applied to it.

PRE LOOP

You can connect an external effects processor to the PRE
LOOP SEND/RETURN jacks and use it as one of the GT-
PRO's effects.
This is convenient when you want to have distortion, wah, or
other external effects processors connected ahead of the
effects chain (p. 22).
Switch PRE LOOP on and off by pressing [PRE LOOP].
• You cannot change the connection sequence in PRE
LOOP. Effects are always connected ahead of the front
panel INPUT LEVEL knob.
• Guitar synths, the Harmonist effect, and other effects
that use processes requiring detection of performance
data may not function properly when PRE LOOP is
switched on with distortion effects connected to PRE
LOOP.
• PRE LOOP is unavailable when the Input Select (p. 90, p.
96) parameter is set to "USB In."
