Marshall Modified JCM800 and 1959 models
Word on the street is that Marshall is about to drop two new amp heads at NAMM 2025:
- Marshall Modified JCM800: Expect a modern take on the classic, with updated features and a killer tone.
- Marshall 1959 Reissue: A faithful recreation of the legendary plexi, for those who crave that vintage roar.
More leaked Marshall products follow the new pedals range based on their classic amps and the Studio 900 20-watt head based on the JCM900.
UPDATE Now Officially Released
JCM 800 Key Features
- Mid-Shift Switch – When activated the controls shifts the frequencies to emphasize mid range content. The result is a fuller, fatter sound.
- Two Overdrives – Two overdrive pedals on a Marshall amp can create interesting tones and give you more tonal options!
- Tight Sound – The tight switch produces a tighter, snappier low end.

- Bright Switch – Brighten up those clean tones for more elegant tonal choices.
- Master Volume – Control the volume with even more ease with the addition of the Master.
- Two Overdrives – Two overdrive pedals on a Marshall amp can create interesting tones and give you more tonal options!

One thought on “LEAK: Marshall Modified JCM800 and 1959 – 100 Watt models coming”
How is it that Marshall can offer 2 new heads when the JVM head I ordered from Sweat Water 10 months ago is still on back order and they say it won’t be available for yet another 6 months. Also the 4-12 cab is also back ordered. What’s really going on?
