The Meaning of Marshall Model Names?

Post by Hot 'Lanta Cat » Sun May 27, 2018 3:12 am

Anyone want to enlighten us about the Marshall model letter system?
Do all the JTM / JCM / JMP / JVM have a meaning? Jim Marshall's family initials or something?

I think you are right. Initials of his daugther, wife or/and himself, depending on model.

That family initials thing had been posted in other threads - but my 205 will always be Vintage Modern to me, named after the two channels.
JVM205h. Added 100K from R94/C43 to ground for V1b (OD Channel) gain reduction. Installed 1000pF in series with 47K, in parallel with R58 (82K), to reduce power amp squeal. V3 Valve Wizard diode protection mod. Active power soak for more EL34 goodness.
Guitars: Angus Young Sig SG w/ Pearly Gates Neck and Custom Custom Bridge, Les Paul Special (2 pups) w/ SD Stacked P90s. And occasionally a Warmoth Strat w/ Dimarzio True Velvet in N, M, SD P-Rails in B.
HD500x in 4CM for all pedals and Midi control of 205h (grounds lifted on two of the signal cables).

Confirmed :)

https://marshall.com/live-for-music/history-of-jcm800

"The year was 1981. The hair was big, the fashion outrageous and the Marshall sound was about to dominate the music industry. After 15 years with our exclusive amp distributer, Rose-Morris, we decided to launch a new product. Named after Jim Marshall’s initials and car registration plate, the JCM800 is still one of the most iconic creations in amp history. "
