9. Boost
This control affects how much your signal level is boosted when the boost is active.
Higher settings (clockwise) will increase the amount your signal is boosted. The Boost
Pre/Post toggle switch changes the position of the Boost in the signal chain.
Pre-Boost - This setting places the Boost before the preamp stage. High levels of
Pre-Boost will push the preamp harder and result in more saturation. This setting is
ideal when toggling between a rhythm and lead tone, with the Boost bypassed and
active respectively. The Pre-Boost has a maximum boost of 12dB.
Post-Boost - This setting places the Boost after the preamp stage and before the
Response/power amp stage. This setting is perfect to engage a 'solo boost', a flat
increase in level without affecting your preamp tone. This setting can also be used to
push the Response/power amp stage into overdrive, when used in combination with
high settings of channel and Master Volume. The Post-Boost has a maximum boost
of 6dB.
The Boost level and Boost position are saved when you store a patch.
10. Boost Footswitch
The Boost footswitch toggles the Boost on and off. The LED will light up when
the Boost is active. This is a global setting and it is not saved when storing a
patch.
Hold the Boost footswitch for 2 seconds to toggle between Manual Mode and
Patch Mode. When the amplifier is in Manual Mode, the sound will reflect the
current physical position of the controls. If the Reverb or Boost are active when
switching to Manual Mode they will be bypassed.
When in Patch Mode, the Channel LED colours will be as follows:
Clean - White
Crunch - Orange
Overdrive - Red
When in Manual mode, all Channel LEDs will be white and the Recall Indicator
(17) will stay illuminated.
Whilst in Manual Mode, any of the controls can still be modified by an external
source (Blackstar Architect software, MIDI controller), but this means that then
the sound will no longer represent the physical positions of the knobs on the
front panel.
Out of the box, or after a factory reset, your amplifier will start-up in Patch Mode.
This setting can be changed with Blackstar's Architect software. Navigate to the
settings panel and deselect 'Start-up in Patch Mode'.
11. Reverb
The Reverb knob controls the amount of Reverb applied to your guitar tone, with
low settings in the counter clockwise direction and high settings clockwise.
Use the Reverb type switch to alter the character of the Reverb:
10
Dark - Warm and resonant
Light - Airy and smooth
The Reverb level and Reverb type settings are saved when you store a patch.
The Reverb time and tone can be customised for each Reverb type using Blackstar's
Architect deep-editing software and saved to your amp.
12. Reverb Footswitch
The Reverb footswitch toggles the Reverb effect on and off. The LED will light up
when the Reverb is active. This setting is global and not saved when you store a
patch.
When the Reverb is active, holding the Reverb footswitch will activate the 'Freeze'
effect. Whilst the Reverb footswitch is held down and the 'Freeze' effect is active, the
Reverb will decay over a much longer period of time, achieving a synth pad-like effect.
Notes played whilst the Reverb footswitch is held will be added to this freeze effect.
13. Response
The Response control delivers three distinctly different and authentic power valve
responses – EL84, EL34 and 6L6. Each setting delivers the response, dynamics, sag
and break-up characteristics of the selected valve power amp. This means that these
amps deliver live without compromise.
Blackstar's power valve responses change the characteristics of the sound from
dynamic and tight to compressed and spongy.
EL84 - Bell-like full bodied Class A with lots of compression and soft break-up
EL34 - Classic British Class A/B full bodied crunch with focussed mids
6L6 - Tight dynamic Class A/B with extended high and lows
This setting is saved when you store a patch.
14. Presence
The Presence control sets the overall treble of the power valve Response (13).
Accentuate percussive and articulate high-end or control aggressive, sharp treble
with this control. This setting is saved when you store a patch.
15. Master
This controls the overall volume of your amplifier. Turning it clockwise increases
the volume. High levels of preamp Volume (8) in combination with high levels
of Master volume will introduce the effect of valve power amp distortion and
compression, the character of which depends on the Response (13) setting you
have selected. This is a global setting and is not saved when storing a patch.
16. Power
This 3-way miniature toggle switch allows the user to switch between three
different power output settings:
100W - This is the full power setting which will give the loudest clean
headroom. Ideal for live and stage use.
