Will overlap a little tonally mainly with Low Mid and Presence. Cut
Upper Mid ACW to thin or “hollow out” tone, reduce bias of middle
guitar strings, or remove honkiness, clunk, or peakiness. Increase
Upper Mid CW to thicken tone, add punch and increase bias
towards middle strings
iv) PRESENCE CONTROL: +/- 7dB centred in narrow band,
approximately @2.8kHz. 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”.
Also use to 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" as used by
Headway should NOT be confused with the controls sometimes
listed on some electric guitar and bass combo amps which use the
“Presence” term to denote high treble. This is because electric
amplifier manufacturers had already started to use the term
“treble”to define low treble centred at around 2-5 kHz and they
needed to find another term for treble, when they added another
control targeting higher frequencies
v) TREBLE CONTROL: +/- 13dB centred broadly @ 10.5 kHz with
shelving.
