ENGLISH From The Guv’nor’ Jim Marshall* I would like to personally congratulate you on choosing the all-valve, 100 Watt, JVM410HJS Joe Satriani Signature amplifier. Joe worked very closely with my top R&D chap, Santiago Alvarez, on this amp for a number of years and the result of this collaboration is fantastic. As is the fact that Joe has quite literally road-tested the prototypes on tour all over the world and also in the recording studio.
ENGLISH First and foremost, thanks for getting my new Marshall Signature Amp – it’s something I’m very proud of. Having a Signature Marshall is an elite fraternity and I feel honored to be part of it. When I look across at the names of the guys who’ve got and have had signature models it’s very impressive to say the least. They’re all players I greatly respect and listen to.
OVERVIEW NB: Please note that the supplied footcontroller lead is unscreened and not suitable for guitar. The 6-button footcontroller features 7 LEDS marked CLEAN/MID-SHIFT, CRUNCH, OD1, OD2, MASTER, GATE & FX. The LEDs for each of the 4 channels are 3-coloured Green, Orange and Red, visually telling you which channel and mode is selected alongside the status of Master, Noise Gate and FX loop.
CHANNEL OVERVIEW CLEAN RED MODE: This just steps the gain up another level. It sounds great and is just a good jangly, slightly broken-up tone. Very useful. The JVM’s front panel is divided into 2 main sections: Channels and Master. Each of its 4 channels has 3 modes which are distinguished by a different coloured light (green, orange or red) appearing in the respective MODE switch; the pre-amplifier’s gain structure is uniquely reconfigured for each and every mode.

14 15 14. SPEAKER OUTPUTS There are 5 speaker outputs available on the rear panel. They are labelled according to the intended impedances: 16 16. POWER AMP INSERT This is a passive loop connected right before the master controls. It is a line level loop so it is recommended to only use high headroom devices to avoid signal degradation. Plugging only into the return jack allows the use of the JVM’s power section overriding the preamp. 16Ω: connect any 16 ohms guitar cabinet to this jack.
FOOTCONTROLLER PROGRAM AND USE The JVM range features a fully configurable footcontroller. Connection to the amplifier requires a standard mono 1/4" jack to jack cable. Any guitar lead will work and practically there should be no limit in its length. same way as if you press the related front panel switch. 410HJS Keys and presets can be assigned as wished without limitation and in any order (again, except the FOOTCONTROLLER / MIDI PROGRAM key).
