The Marshall JVM4 is definitely the Mornach of ALL Marshalls. 4 Channels, 3 Modes EACH (Green, Amber, Red) providing various gain stages. 4 Independent Reverbs (Digital) and 2 Power Amp Settings. This amp has a Global Low Damping & Presence that affects ALL 4 Channels, Seperate EQ/Gain per channel. From Channel 1 Green you start with 'OLD SCHOOL..Non Master Classic Marshall. Channel 2 is in the JCM800 territory (80's) and Channel 3 is JCM2000 range and the Channel 4 goes where no Marshall has gone before...GAIN..GAIN..GAIN...
Footswitching is ingenius using a single TS cable 1/4 -/1/4 you are able to switch through ALL 12 available settings and toggle reverb and the Power Section..and that's just out of the box.. it's totally Programmable. The Amp is MIDI capable.
2 Effects loop (series/Parallel with -10 switch. and the BEST BY FAR Speaker Emulated Line out (XLR Balanced)
You Really Need to Hear this Amp!!
