VP4 OWNER'S MANUAL

Setup: Effects Loop of an Amp

The VP4 can be used in an amp's effects loop for "Post FX".
Aside from the usual steps of checking levels and mono/stereo, no special settings
are required. Use standard guitar patch cables for every connection.
 Connect your guitar to the guitar input of your amp.
 Connect the FX SEND of your amp to VP4 Input L/Mono.
Adjust the loop level to prevent clipping on the VP4.
 Connect VP4 Output L/Mono to the FX RETURN of your amp.
 Use optional Output R to connect to the FX Return of a second amp for stereo.
 The VP4 can also be used before, after, or between other "Post" FX in your
amp's FX loop—in mono or stereo (see VP4 with Other Pedals, previous page).
FAQ: Series Loop vs. Parallel Loop?
While parallel loops were once popular because of how they preserve the
dry tone when used with vintage or less advanced effects, the VP4 and
other modern processors are able to offers excellent sonic performance in
a series loop.
In fact, designing and dialing in sounds for a series loop is easier and more
flexible because the effects chain acts as a single processing path. Not
only does this allow you to use effects that process the dry signal, such as
EQ, compression, volume, etc., but each effect can also process the full
signal from the previous one, leading to unique interactions and a more
complex final sound. Trem-flanged-shimmer-echoes? Easy!
If your amp's effects loop is parallel, you must instead ensure that no dry
signal passes through the VP4. This means usually means using only time-
based effects with MIX set to 100% or "Kill Dry" turned on, and "Routing"
set to "Parallel". (Find these options in HOME > Preset Mix/Routing)
If your amp is switchable, the "Series" loop setting is easier to use and may
be the better choice.

Presets designed specifically for FX Loop "Post" setups can be found in
banks P, Q, and R. However, some of the presets intended for "Pre" setups
will also potentially work in this type of rig. These have the symbol ">" at
the end of their name.
Bank R contains a preset template for amps with a parallel FX loop. For
such rigs, be sure to follow the instructions in the box at left.
