3.2.4 PRESENCE Control: +/- 7dB centred @ 2.8kHz
Allows control of Presence which noticeably overlaps into lower treble
and upper mid range areas but offers a useful, narrow but distinctive
area of control.
CUT Presence ACW to reduce clunk, peakiness or harshness,
to hollow out sound subtly and reduce low end brightness, reduce bias
of top 2-3 guitar strings, thin the treble, tame low treble feedback and
mellow the sound. A Presence cut is also thought to reduce the Piezo
response effect which is sometimes partly characterised as “quacking”.
INCREASE Presence CW to thicken treble, increase punch and
increase bias to top 2-3 strings.
N.B. Pro Audio or dictionary defined “Presence” should NOT be
confused with the controls sometimes listed on Electric Guitar combo
amps which use the term to denote high treble.
3.2.5 TREBLE Control: +/- 13dB Centred broadly @ 10 kHz
HIGH allows control of treble at higher end of the audio spectrum
which offers you increased brightness on turning CW or a jazzy mellow
sound on turning ACW. Treble overlaps mainly into Presence area.
However, low strings will produce high tones or harmonics.
Cut Treble ACW to reduce high end feedback, harshness, externally
generated hiss, squeaks from new strings or to compensate for
over-bright pickups or hard reflective rooms.
Increase Treble CW to compensate for old, dull strings, weak top
strings, mellow pickups or dull, boxy rooms and P.A’s.
Overall 5 Band EQ can be switched to both channels combined or to
either channel separately.
EDB-2 may operate a dual system by applying 5 Band EQ to one
channel (or both channels) and notch filter to the other channel.
If you need 5 band EQ individually on each of two outputs on one
instrument, you could use two EDB-2 units into a Mixer.
