1. Voice
The Voice control changes the preamp voicing. Select a preamp character and
sound that suits you.
USA - Inspired by classic American amps of the mid '60s. Very clean, dynamic
and bright, but with a solid low-end and controlled mids. A perfect pedal platform.
UK - 'Classic' valve preamp based on a much-loved British Class A amplifier
of the early '60s. A low to medium gain preamp that can be used clean, warm or
mildly overdriven. Popular choice for a 'pedal platform' or as a responsive crunch
tone. The valve power stage is set as 'open-loop', which has a looser feel with a
resonant bottom end and lively highs.
Flat - Neutral preamp for use with external preamps and amp modellers.
Features a semi-parametric EQ, transparent with controls set to 12 o'clock
This setting is saved when you store a preset.
2. Gain
The Gain control adjusts the amount of overdrive or distortion. Low settings,
counter clockwise, will deliver a clean and articulate tone. As the Gain control is
turned clockwise the sound will become more overdriven, moving through beautiful
crunch tones, with maximum distortion in the full clockwise position. This setting is
saved when you store a preset.
3. Bass
The Bass control adjusts the level of low-end frequencies in your tone. The tone
controls are tailored to the selected voice. The USA Voice has a more pronounced
low end, whereas the UK Voice has a more controlled bass response. This setting
is saved when you store a preset.
4. Middle
The Middle control adjusts the level of mid-range frequencies in your tone. The mid-
range frequencies are particularly important in setting the amount of 'body' your tone
has. With the Middle control set to its minimum position (fully counter clockwise) the
sound will be scooped. As the Middle control is increased (clockwise) the amount of
'body' is increased. This setting is saved when you store a preset.
5. Treble
The Treble control adjusts the level of high frequencies in your tone. At low settings the
sound will be warm and dark in character. As the Treble control is increased the sound
will become brighter. This setting is saved when you store a preset.
6. 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. This setting is
saved when you store a preset. The Reverb type, time and tone can be customised
using Blackstar's Architect deep-editing software and saved to your amp.
