FEEDBACK LOOPS
Feedback loops allow you to combine effects in interesting ways and then route the output back to the input. The
figure below demonstrates this by using an overlay of a preset illustration rendered in Axe-Edit.
Signal enters the grid at (1), passes through the AMP and CAB, and reaches the output (2), where it is heard in
the speakers as you play. Meanwhile, a tap of this main line at (3) carries signal to a Graphic EQ, and a Delay set
to 500 ms, no feedback, mix 100% wet. Because of the mix setting, nothing comes out of the Delay for 500 ms.
Then, the first echo is routed by a cable (4) to the output (2). This echo simultaneously enters the Send block
(5) and is routed to the Return (6). From here it again passes through the GEQ—and hits the delay again. Each
previous echo that cycles through has one extra pass of any other effects in the loop. The purple dotted line
shows the imagined path that signal takes between Send and Return.
This feedback loop of GEQ
Delay Send Return would continue forever if the Return Level parameter didn’t
make it a bit quieter each time so that it eventually fades away.
So to review, the Send “transports” signal to the Return, where Return Level controls the amount of feedback.
Countless variations of Send/Return loop presets are possible when you use different effects, vary their order, or
enter and tap the loop in different places.
EXTENDED LAYOUTS
The 14x6 grid will suffice for the vast majority of long, complex routings. However, sometimes the "need to
exceed" means building an effects chain that is longer than the number columns available in the grid. The Send
and Return blocks can be used for exactly this purpose. Place a Send block at the end of your first chain and
place a Return block at the beginning of another, setting Return Level to “100%”. Continue through other effects
to an output as illustrated below. By the way, this real preset with 28 blocks hits just over 80% CPU usage!
