11 EPB II Lo-Lead
Inspired by 2011 ENGL Powerball II
The model 11 EPB II Lo-Lead it is designed to deliver controlled, dynamic and less compressed distortion, ideal for:
- Rock, hard rock and expressive leads
- Defined and articulated rhythms
- High gain sounds but more “open” than Hi-Lead mode
It's a cross between Crunch and Hi-Lead: less gain, more dynamics and more control.

Controls
Bottom
Activates the emphasis on low frequencies:
- Y → more depth and body
- N → tighter lows
- Useful for adding weight without losing definition
Mid Boost
Increases mid frequencies:
- Y → more presence and definition
- N → more open/scooped sound
- Perfect for lead rock
Treble
Control the high frequencies:
- Low → soft sound
- High → bright and defined
Middle
Control the mid frequencies:
- Low → more hollow sound
- High → more body and presence
Bass
Control the low frequencies:
- Low → tight and controlled
- High → full and round
Presence
Control the final brilliance:
- Low → softer sound
- High → more open and aggressive
Deep Punch
Controls the low end response of the power amp:
- Low → more controlled lows
- High → more impact Less extreme than Hi-Lead
Gain
Control saturation:
- Low → crunch
- Middle → rock distortion
- High → full lead but not too compressed
- More dynamic than Hi-Lead
Gate
Control the noise gate:
- Low → natural
- High → cleaner but less sustain
Master
Controls the final volume of the amplifier:
- Low → less pressure
- High → more push and body
Output Level
Controls the overall final volume:
- Negative → attenuation 0 d
- B → neutral
- Positive → boost
Pro Tips
BEHAVIOR OF THE AMPLIFIER
- More open and dynamic high gain
- Less compressed than Hi-Lead
- Excellent definition in the rhythms
- It responds better to the touch and volume of the guitar
Advice:
- Mid Boost ON → more present leads
- Moderate bottom → balance between punch and definition
- Medium-high gain → sweet spot rock
- Light gate → maintains dynamics
Final advice:
- Use Lo-Lead to rock and expressive leads
- Use Hi-Lead to metal and extreme gain
- Mid Boost ON → always useful in live performances
- Perfect balance between dynamics and distortion
