7. ISF
The patented ISF control works in conjunction with
the Bass and Treble controls. It allows you to choose
the exact tonal signature you prefer. Fully counter
clockwise has a more American characteristic with a
tight bottom-end and more aggressive middle, and
fully clockwise has a British characteristic which is
more ‘woody’ and less aggressive.
Unlike conventional ‘contour’ controls and parametric
equalisation systems, the Bass and Treble controls remain interactive with each
other just like in a traditional guitar amplifier tone stack. This leads to a very familiar,
musical response. This setting is saved when you store a patch.
8. TVP (True Valve Power) Selector
Blackstar’s patent-applied-for True Valve Power offers six distinctly different power
valve responses – EL84, 6V6, EL34, KT66, 6L6 and KT88. When engaged it delivers
the response, dynamics, sag and break-up characteristics of a valve amp and
uniquely delivers the same acoustic power output as an equivalent valve power
amp. This means that these amps deliver live without compromise – True Valve
Power means LOUD as Valve

.
TVP changes the characteristics of the sound from compressed and spongy to
dynamic and tight.
EL84
Bell-like full bodied Class A with lots of compression
6V6
Crisp Class A with high compression and tight mids
EL34
Classic British Class A/B crunch with full bodied soft break-up
KT66
Rich and warm vintage British hot biased Class A/B
6L6
Tight dynamic Class A/B with extended high and lows
KT88
Tight, bold and dynamic Class A/B with strong low end
As you move from EL84 to KT88 the amount of compression and overdrive available
from each valve response is increased. Additionally, when either of the two clean
voices is selected the output compression and overdrive are affected by the gain
control.
This setting is saved when you store a patch.
9. TVP (True Valve Power) Switch
Pressing this switch turns TVP on and off. The internal button LED will light to show
TVP is on. When the LED is off, TVP is not active and the TVP Selector will be
deactivated. This setting is saved in a patch.
NOTE:
With TVP off the power amplifier has a linear response and you will not be
able to achieve the valve-like sag, compression and power that TVP delivers.
Effects
Up to three studio quality effects can be switched on at any time.

Front Panel
1. Input
Plug your guitar in here. Always use a good quality screened guitar lead.
2. Voice
The Voice control changes the preamp voicing, ranging from ultra clean to extremely
overdriven.
Clean Warm – Very clean, dynamic
Clean Bright – ‘Boutique’, will break up when pushed hard
Crunch – Classic medium gain overdrive
Super Crunch – More gain and punch than Crunch
OD 1 – Hot-rodded Master Volume overdrive
OD 2 – Mid boosted hot-rod overdrive
This setting is saved when you store a patch.
3. Gain
The Gain control adjusts the amount of overdrive or distortion. Low settings (counter
clockwise) will deliver a clean sound on the edge of break-up. As the Gain control is
turned clockwise the sound will become more overdriven, moving through beautiful
crunch tones until, at its maximum position, a full distorted tone is achieved. This
setting is saved when you store a patch.
4. Volume
This controls the preamp volume. Turning it clockwise increases the volume.
High levels of volume will introduce the effect of valve power amp distortion and
compression, depending on the TVP (8) setting you have selected. This setting is
saved when you store a patch.
5. Bass
The bass control adjusts the amount of low-end frequencies in your tone. This amp
has an advanced tone shaping circuit which allows the tone to be tight and cutting
(counter clockwise) to warm and thumping (clockwise). This setting is saved when
you store a patch.
6. Treble
The treble control allows exact adjustment of the treble frequencies within the sound.
At low settings (counter clockwise) the sound will be warm and dark in character.
As the treble control is increased (clockwise) the sound will become brighter. At the
maximum settings the sound will be aggressive and cutting. This setting is saved
when you store a patch.
