Marshall MG50DFX is a 50-watt solid-state 1x12 guitar combo amplifier, made in 2003. Back is missing, but the electronics work fine.
Features
Power: 50 Watts (RMS) through a single custom-voiced 12" speaker.
Channels: Two independent channels (Clean and Overdrive), both footswitchable.
Equalization: Dedicated 3-band EQ (Bass, Middle, Treble) for each channel.
Valvestate Contour: The Overdrive channel features a Contour control that allows you to scoop out or boost critical mid-range frequencies.
FDD (Frequency Dependent Damping): A signature Marshall feature for this series that alters the power amp characteristics to mimic the dynamic punch and resonance of a real tube amplifier.
Onboard DFX: Built-in digital effects including Chorus, Delay, Flanger, and an independent Reverb (with its own level control).
Connectivity: Emulated Line Out/Headphone Jack (for silent practice), CD/MP3 input, and an Effects Loop.
