Vintage 1991 Marshall JCM900!
 100 Watt All Tube Head! Made In England!
This is really Cool. You are looking at a Vintage 1991 Marshall JCM900. This is a Model 4100 All Tube 100 Watt Head. What comes dressed in black tolex and breathes the fire of the gods when engaged in a sonic maelstrom of epic proportions? This 100W Marshall JCM 900! This thing rips. Classic Marshall throaty tones, round cleans and an onboard reverb--what more could you want?

This high gain, dual reverb, all-valve 100 Watt head is still a players favorite. Known for its tone and workhorse roadworthiness, the JCM900 4100 has many fans due to its feature set and versatility.

Channel A is voiced to be sparklingly clean on lower gain settings, building to a raunchy crunch when driven harder. Channel B takes the gain higher producing tones from silky smooth distortion to searing, saturated scream.

The JCM900 4100 is equipped with a series FX Loop with its own Level control for use with rack FX or stomp boxes.

The JCM900 series is still used today by artists including Zach Blair of Rise Against and Joe Gosney of Black Peaks, who notes:

“The JCM900 is awesome. It manages to do everything an amp should ever do without the need to over complicate things.”


This monster sounding legendary rock amp is the Real Deal! NOT a Reissue. The Original. You can Rip Paint off of the Walls!
This is the EL84 Power Tube Version.
Footswitch NOT Included
Cosmetics: Good Condition. There are a couple of tears in the Tolex. A few scratches and scuffs as well. Instrument Control bezel lettering is clear and legible. Dripping with "Mojo" It is used. Not perfect. Look at the pictures closely. They will tell the story.
