These two 1/4 inch phone jacks are provided to accept the Channel Select Footswitch ( that should have
come with your V-TWIN ) and the ( optional ) Effects Loop Footswitch. When either or both of these

EFFECTS LOOP:

The V-TWIN incorporates a Parallel Effects Loop to insure that your Tone stays as pure as possible, free
from degradation caused by processors that might use less than optimum operational amplifiers in their mix and output stages. The
Loop is comprised of a MONO SEND and STEREO RETURNS. It also features a MIX Control for determining the Dry / Wet blend.

NOTE By following the suggestion of setting your processors Dry / Wet Mix Control to 100%, you will automatically set the V-
TWINS' MIX Control closer to a "0%" blend of the loop and dry signal ratio. This scheme is almost always the best way to insure
that your sound stays bold and expressive because you will be introducing very small amounts of outside and possibly unfriendly
circuitry into the V-TWIN'S signal path.
