Four channels, each featuring three gain modes, mean the JVM is equally adept at playing cleans, metal, or anything in between. For the classic clean channel the pre-gain stack emulates vintage amplifiers. Alternatively, get that Marshall hard rock sound at the top end of the crunch channel. If you want to go heavier OD1 is perfect, while in OD2, every mode is high gain to allow your lead metal tones to shine through. Add in the three-way EQ in each channel and the presence and resonance controls and you can expertly shape the tone from the power amp.
