Up for sale is a used Marshall MG Series 100DFX 100-Watt 1x12" Guitar Combo Amplifier.

If you are looking for that legendary, aggressive Marshall roar with enough stage volume to cut through a loud live drummer, the MG100DFX is a fantastic budget-friendly gigging machine. Pushing 100 Watts through a heavy-duty custom 12" Marshall/Eminence speaker, this amp features a versatile 2-channel design (Clean and Overdrive) with two distinct voicings per channel (Clean/Crunch and OD1/OD2). It also comes equipped with a built-in digital effects section ($DFX$), giving you instant access to Chorus, Delay, Flanger, and a dedicated natural Spring Reverb emulation.

Condition & Service Notes:

This amplifier is in Perfect Playing Condition and has been thoroughly bench-serviced.

• Performance: 100% fully functional. Every control knob, toggle button, and input/output jack works exactly as it should. The potentiometers have been cleaned and treated—there are no scratchy pots, dead spots, or unwanted signal clipping.
• Operational Note: Like many high-wattage solid-state amplifiers from this era, the idle floor hiss on this model is naturally quite pronounced when powered on. The circuit has been fully checked over by a technician and confirmed to be operating exactly as intended; this characteristic idle level is completely normal for this specific Marshall model and disappears completely once you start playing.
• Cosmetics: Shows significant cosmetic wear all around the chassis. The black Tolex exterior finish is fraying, peeling, and shows various tears and scuffs from road use. The front control faceplate and gold accents also show expected minor signs of age. If you don't mind a heavily "relic'd," road-worn look, this amp is an absolute workhorse structurally and electronically (please see all detailed photos).
