Quick Start Settings
If you're looking for a good starting point, try these settings. Remember that
every guitar and speaker cabinet sounds different, so try both inputs, and adjust
the Focus and Presence to suit your taste.
Quiana and Fandango Differences
The Quiana and Fandango are very closely related. Whenever the Quiana is
mentioned in the manual, it is safe to assume that the Fandango will function
similarly. In cases where the two amps are different, the words "Quiana only" or
"Fandango only" will be used.
