*Rare* Dummy Marshall 4100WM (JCM 900 Wall Mounting) 100W Valve Amplifier Dummy Shallow Wall Mount Stage Backdrop Shop Fitting

Rare Marshall 4100WM “JCM 900 Wall Mounting” Dummy Head – Stage / Shop Display Prop

A very unusual and seldom-seen Marshall 4100WM wall-mount dummy head, designed as a visual prop - NOT A FUNCTIONING AMPLIFIER. These were produced for stage backdrops, retail displays, and shop fittings where the iconic Marshall look was required without the weight, heat, and electronics of a real amplifier.

Styled after the classic JCM 900 100W Hi Gain Dual Reverb (Model 4100) head, this piece faithfully reproduces the famous Marshall aesthetic: black levant covering, white piping, gold control panel, and the classic script logo. From the audience or across a room it looks exactly like the real thing, making it ideal for studio décor, rehearsal spaces, music shops, stage sets, photography, or film production.

Unlike a real head, the 4100WM is a shallow dummy unit designed specifically for wall mounting, allowing it to sit neatly against a wall while still presenting the full Marshall front panel look.

Condition

Listed as excellent condition but basically new in box. Presents extremely well and would look fantastic mounted in a studio, rehearsal room, shop wall, or stage backdrop.

These are rarely seen on the market as most remained installed in stores or stage rigs.

I also have the matching Marshall 1960B flat cabinet (dummy/display) available, which will be listed separately amongst my other listings if you’re interested in completing the full Marshall wall display.
