The tone-monster workhorse is back for an encore.

The Marshall JCM900 4100 100W head had long been a favorite of rock and metal guitarists starting in the 1990s, because of it’s versatile, full-bodied, undeniably Marshall tube overdrive, sparkling clean tones, stage-capable power and thick two-channel reverb. And now it’s back.
The head features two footswitchable channels (low-gain A; high-gain B) with shared four-band EQ — Presence, Bass, Middle and Treble — as well as independent Volume, Reverb and Gain controls. Turn it around, and you’ll see a series FX loop with level controls, optional footswitch input and the bread and butter of the classic Marshall tone, the tube complement: three ECC83 tubes and four 5881 tubes.


  • Power: 100W tube
  • Series FX loop
  • Tubes: three ECC83; four 5881
  • Optional footswitch
  • Dimensions: 29.5” x 12.2” x 8.6”

Get your hands on one, and you’ll see why the world is better with the JCM900. Order today!
