As you plug in your guitar(s) and amp(s) you will
immediately see the corresponding A or B INST

When you touch the A/B switch, the signal path LEDs will clearly
show the input/output configuration. And, at the same time, the
A or B input LED will flash to indicate the active tuner channel.

Steps legend to display Flat Tune status. The LED below the

each position to the left of zero represents ½ tone down from
standard tuning. The current Flat Tune status will be displayed
briefly the first time the

LEDs strobe left to indicate flat, right to indi-

played note is from being in tune.  A pitch far from the closest
note (as indicated by the Note LED) will strobe quickly. As the

NOTE

: As in all strobe tuners, it can be difficult to get the strobe

effect to stop completely. This is due to the extreme accuracy
of the strobe tuner and the fluctuation in string vibration fre-
quency as it varies from “first plucked” to sustained note.
