Marshall Launches Its Next Generation Of All-Valve Amplifiers, The JVM Series [ Winter NAMM 2007 ]

United States
New, English made amps feature 4 independent channels with 3 switchable Modes per channel, extended gain, intelligent footswitch, MIDI switching, dual FX loops and more

NAMM SHOW, ANAHEIM, CA, January 18, 2007 — Marshall Amplification introduces the JVM Series amplifiers — the most versatile and highest gain Marshall all-valve amplifiers to date. The UK-built series is comprised of the JVM410H 100-Watt Head and JVM410C 100-Watt 2 x 12″ Combo. These all-valve (5 x ECC83s, 2 x EL34s) amplifiers feature four independent, footswitchable channels (Clean, Crunch, OD1 & OD2) with three footswitchable Modes per channel, yielding a total of 12 different “amps.” Each Mode has its own unique gain structure, offering a wide variety of sounds ranging from the cleanest cleans to the filthiest Marshall, high-gain distortions ever. Each channel’s three modes are indicated by a bright LED that glows either green, orange or red — depending on which Mode is selected.

Featuring an extremely straightforward, familiar front panel, the Head and Combo boast eight LED switches and 28 controls including Volume, Bass, Middle, Treble and Gain for each channel, dual Master Volumes plus Resonance and Presence. Both amplifiers also house a studio-quality, digital reverb with level controls for each channel.

In addition to the Channel/Mode switches, the amps also feature front-panel switches for Reverb (off/on), Master Volume selection (1 or 2) and FX loop (on/off). Onboard logic ensures switching is swift and silent plus remembers the last position of each front panel switch in all 12 Modes — Reverb (on/off), FX Loop (on/off) and Master Volume (1 or 2), even after the amp has been powered down.

For the ultimate in control, Marshall has developed an intuitive, “intelligent,” six-way foot-controller that can memorize user’s front panel switch settings. Seven easy-to-read, multicolored LEDs reflect every front panel switch setting, including the channel Mode being used. This patent-pending technology allows single front-panel switches or entire setups (Channel, Mode, Reverb, FX Loop and Master Volume switch setting) to be simply assigned to any one of the foot-controller’s six switches. For user convenience, the foot-controller connects to the amps via a standard guitar cable.

In response to pro player requests, all switching can also be done via MIDI. Both amplifiers incorporate two FX loops — Series/Parallel and Parallel, the former of which is footswitchable. Also included on the rear panel is a Speaker Emulated XLR line out.

To provide a full sonic spectrum, the JVM410C 2x12″ Combo is loaded with two different Celestion 12″ speakers — one Vintage and one Heritage. The JVM410H can be partnered with any Marshall 4x12″ cabinet(s)

The Marshall JVM Series Amplifiers are available in early 2007, with U.S. MSRPs as follows: JVM410C 100-Watt Combo — $3000.00; JVM410H 100-Watt Head — $2500.00.
