When you use the serial loop for an effects unit like this, then your signal will
have been ADA converted at least once. Tone junkies and vintage freaks alike
will more than likely have hives developing by now. But, as always, there is a
better way. Using the Parallel loop and the mix (labeled “Volume”) control on the
back determines how much effect signal is being added to the original signal,
which now still flows through the amplifier. There is always an analog connection
between the send and return jacks: a parallel loop!
Important:
You must set the mix control on the effects unit to 100% wet when
using the parallel loop. Otherwise there will be nasty phasing problems resulting
in unsatisfactory tone. The signal portion that is unaffected by the mix control in
the effects unit would reach the amplifier at a different time due to the cabling,
and cause phasing cancellations.

Switch-able Loop as additional Volume Control
Those of you who can live without processors in the parallel loop can use this
loop for a second master volume for each channel.
To do this, just loop a short 1/4” cable from the switch-able send to parallel loop
return. Now you can choose a second master volume by turning the mix control
past 1:00 PM to full open, and push the ‘ Loop” button to activate your second
master volume. Now, with the loop activated, the mix control can act as another
way to control volume.
3.2.4
Switch-able Loop for external pre-amp
One might extend one’s tonal variety by hooking up an external guitar pre-amp to
the switch-able return jack. Now the external preamp, once selected via the
“Loop” function, can feed the Herbert’s power amp.
3.2.5
Switch-able Parallel Loop
To route your effects signal parallel to the original signal, connect the switch-able
send to the input of your effects unit and go from the output of your effects unit to
the parallel return. Now you can switch the send to the effects unit on and off via
midi, with the effects signal decaying naturally when the loop is turned off.

Tuner Out
You guessed it – it’s for a guitar tuner. Stays lit while mute is activated. So you
can tune without annoying your band members, or the audience. Elegant, no?
