Features and functionality

The JCM 900 4100 Dual Reverb is noted for being a solid state opamp preamp, unlike the all-tube SLX model.
Source -
The JCM 900 is considered darker sounding than the JCM 2000 DSL, with less low end unless EQ is used in the loop.

The JCM 900 MKIII is compared to the JCM 800 but with extra diode clipping for more attack, differing from the SL-X's extra preamp tube.

Mods and upgrades
-
It's recommended to replace the stock G12T-75 speakers for a less harsh sound, with V30s or greenbacks as popular alternatives.
