Marshall JVM410HJS Joe Satriani - TUBE HEAD FOR GUITAR 4 CHANNELS 100W

(This text is machine translated) The most important difference from the original JVM410 is that the reverbs have been replaced with four noise gates, one for each channel, and each with its own threshold. A Shift Mid button has been added and can be used with both OD1 and OD2 channels. The Clean channel is based on the 6100 in green mode, the red modes being the hottest variations. The Crunch channel builds on the original JVM410 crunch by adding some of the popular Marshall "AFD" circuit. The OD channels are based on the JVM410 OD1 but with slightly scaled gain and a smooth transition between modes. The Shift Mid button determines the difference in character between the original JVM410 OD1 and OD2 sounds, shifting the mids from about 650khz (Shift Mid off) to about 500kHz (Shift Mid on).
