MOP TOP LIVERPOOL GUIDE TO CONTROLS
(in order of signal flow)
Independent SansAmp Section:
DRIVE A and DRIVE B
Adjusts the overall amount of gain and overdrive, similar to when the
output section of a tube amp is being pushed. The first half of the rota-
tion will increase the volume as well as the overdrive.
CHAR A and CHAR B
Sweeps through an entire range of tonal possibilities associated with
Vox-style amplifiers. Char A’s territory covers cranked up tone stacks.
Char B stays in uncranked territory. Each Character also influences the
attack and drive characteristics. Therefore, you may need to adjust your
gain and tone settings after tweaking the Character controls.
CHAR A Range of Settings:
• Below 12 o’clock
serves up the tone of a Top Boost with controls
set to 9:00, for a throatier clean sound and warm overdriven tones.
• Advancing towards 12 o’clock
brings in classic British mids.
• Passing 12 o’clock
increases clarity to crunchy and overdriven tones.
• Full up
adds the upper mid crackle of pushed Alnico speakers.
CHAR B Range of Settings:
• Below 12 o’clock
serves up the tone of a Top Boost with controls
set to 3:00, for full clean sound with lots of bass and highs.
• Advancing towards 12 o’clock
brings in classic British mids.
• Passing 12 o’clock
brings in the vocal quality of “Woman Tone.”
• Full up
boosts the low mids for non-Top Boost AC30-style tone.
LOW, MID, HIGH
On-board post-EQ section gives you full control, like having a studio
mixing board at your fingertips. Unlike passive tone controls that only
cut, these active controls cut and boost ±12dB. Low is tuned to 125 Hz;
High frequency is 3.2kHz. Mid is tuned to 325 Hz.
MID SHIFT SWITCH
Shifts the frequency of Mid from 325 Hz to 250 Hz.
HIGH SHIFT SWITCH
Shifts the frequency of High from 3.2kHz to 4.5kHz.
VOL A and VOL B
Adjusts the volume of the SansAmp section.
Independent Boost Section:
BOOST
Uniquely offers 2 boosts in one knob: At 12 o’clock, it’s flat.
Up to 12dB Treble Boost
when you turn clockwise for a brighter,
louder, edgier ‘60s and 70s vintage vibe.
Up to 12dB Mid-Range Boost
turning counter-clockwise, which
tightens up distortion, rhythm and lead tones for more modern vibes.
SPEAKER SIMULATION
Speaker simulation is an integral part of the SansAmp circuitry. It is de-
signed for a smooth, even response as would be achieved by a multiply-
miked cabinet, without the peaks, valleys, and notches associated with
single miking. The shape of the speaker curve will not adversely effect
or interfere with the frequency response of your own cabinet. The
speaker simulation works in tandem with the EQ controls to custom
tailor the overall sound.
Mop Top Liverpool:
tuned to match English Alnico Bulldog-style
speakers.
