Used demonfx Simple guitar DI box amp simulator

The Demonfx SIMPLE is a 100% true analog zero-watt amp simulator, cabinet simulator, and stereo DI box. Heavily inspired by the popular DSM & Humboldt Simplifier, it acts as a total ampleless fly-rig solution. It gives you all the tools required to go direct to a front-of-house (FOH) PA system or a studio recording interface without a real amplifier on hand.

Key Features & Architecture

• Three Classic Analog Preamps: Features a 3-band passive tone stack alongside a toggle switch to flip between three distinct, iconic amplifier flavors:
  • American: Recreates a classic, sweet, and dynamic 60s blackface style clean tone.
  • AC Brit: Delivers a bright, sparkly, three-dimensional British chimer reminiscent of a vintage AC30.
  • MS Brit: Offers a classic, clean-to-crunch vintage Plexi-style voice that defined classic rock.
• Power Amp Emulation: Approximates the physical interaction of power tubes and output transformers via dedicated knobs and toggles. You can choose between EL34 (compressed, mid-focused), 6L6 (dynamic, open, deep bass), or KT88 (extended low-end response) tube simulations, adjusting your presence and resonance peaks accordingly.
• Stereo Cabinet Simulator: Provides dual independent left/right cabinet simulators. Toggle switches let you select a 1x12 combo, 2x12 cabinet, or 4x12 stack for each side independently. Pair it with physical "Mic Position" knobs to control high-end roll-off as if moving a real microphone off-axis.
• Immersive Spread Control: Shiffs the phase of key frequencies on one side to generate a pseudo-stereo soundstage. This delivers a massive, "dual cab" room separation effect even if you are just monitoring on headphones.
