Key Features & Sound

• Amp Emulation: Modeled after the high-gain tone, saturation, and harmonic response of the Peavey 5150 / 6505 amplifier series. 
• Two Channels:
• • Overdrive/Lead Channel: High-gain, tight, and aggressive modern metal/rock tone.
  • Clean Channel: A universal clean channel styled after classic Fender amps, equipped with a clean boost control (up to +8 dB). 
• Three Independent Outputs: Can be used simultaneously:
• • Drive Out: For connecting to the front input of a traditional guitar amplifier (stompbox/effect mode).
  • Preamp Out: For connecting straight into the power amp / effects loop return of an amplifier.
  • Cab Sim Out: Features a built-in cabinet simulator for direct connection to an audio interface, mixer, or PA system. 
• Bypass Mode: Uses a partial active bypass that preserves your instrument's natural tone and reduces cable-length signal loss when switched off
