Bypass:

• Buffered Bypass:
  • Keeps the signal intact and clean when the pedal is turned off, preserving the original tone of your instrument.

Controls:

• SUSTAIN Knob:
  • Adjusts the amount of compression. Higher sustain will make quieter notes louder and louder notes quieter.
• ATTACK Knob:
  • Controls the speed at which compression kicks in. A fast attack compresses quickly, while a slower attack lets transient sounds (like pick attack) through.
• TONE Knob:
  • Shapes the tone of the output signal, allowing you to adjust for brighter or darker sounds.
• LEVEL Knob:
  • Adjusts the output volume of the compressed signal to balance with the bypassed signal or set the desired loudness.
