Connect an electronic tuner
The Firefl y is equipped with an 'always-on' TUNER output that is designed to hook up an
electronic tuner to provide constant visual feedback while performing. The TUNER output is
buffered and electronically isolated to prevent noisy digital tuners from bleeding clock noise
into your instrument sound. The TUNER output is tapped before the tube gain stage provid-
ing a clean instrument output that can be used to split the signal to another preamp when a
tuner is not connected.
JR•2 remote footswitch
For even more control over the Firefl y, you can add the optional
JR2 footswitch. This two button footswitch can activate the
MUTE function for silent on-stage tuning via the always-on
TUNER output and toggle between instrument inputs A & B.
For convenience the JR•2 can be connected with either a ¼"
TRS cable or a locking Female XLR ~to~ ¼" TRS cable. Both
connections are offered on the rear panel but only one should
be used at a time.
