Chapter 4 Introduction to Effects and Parameters

LOOP (External Effects Loop)

This allows you to connect an external effects device to the
SEND and RETURN jacks and use it as part of the GT-8's
effects.
Parameter/
Explanation
Range
On/Off
Off, On Switches the LOOP on/off.
Mode
Normal, Direct Mix,
Switches the LOOP mode.
Branch Out
Normal
Outputs the input to LOOP to the SEND jack and the input from the
RETURN jack to the circuit post-LOOP. Use this when you want to
connect an external effects device serially in the GT-8's effects chain.

SEND
Direct Mix
Outputs the input to LOOP to the SEND jack, mixes the input from
the RETURN 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-8's effects sounds together with the sound with the external
effects device applied to it.
fig.04-110
SEND
Branch Out
outputs the input to LOOP to the SEND jack. The input from the RE-
TURN jack is disregarded. For example, using this with the GT-8's
reverb and delay immediately ahead of the loop allows you to use
the SEND jack as a direct out.

AMP CTL (Amp Control)

By connecting your guitar amp's channel switching jack to
the GT-8's AMP CONTROL jack, you can then use [AMP
CTL] to switch the amp channel.
This combining of the GT-8 and the amp channels allows you
to get an even wider variety of distortion sounds.
Since the Amp Control setting is handled as one of the effects
parameters saved to each individual patch, it allows you to
switch guitar amp channels with each patch.

* To determine how the amp channels are switched when the
circuit is open and shorted, refer to the amp owner's manual,
or actually confirm the sounds by operating the amp.
With Amp Control, not only can you switch amp
channels, you can also use it to switch the amp's effects
on and off, like a foot switch controller.
Note that, depending on the circuitry of the channel
switching jack in the guitar amp used, the Amp Control
function may not operate.
