While there are many profiles out there of the Marshall JVM410, most of them concentrate on sounds with the heavy metal player in mind. This "Classic 410's" pack is fit for Classic Rock and other styles, but (maybe) not so for heavy metal. This pack includes 84 profiles that represent my personal settings of the JVM410H: One setting per channel/mode with 3 different speakers (so 12 x 3 = 36) normal profiles, a direct profile (12), and the merged profiles with the 3 different speakers (so 12 x 3 = 36).
A small introduction about these amps (taken from the manual) :
This is a four-channel amp, and each channel has 3 modes: Green, Orange and Red.
- CLEAN GREEN MODE: this is the cleanest of the three modes and, in keeping with traditional clean amps, it uses a simple and straightforward circuit, keeping the signal as pure as possible. In this mode the channel’s VOLUME control is taken out of circuit as is the case in vintage amplifiers of this nature. This is the only mode where this happens. - CLEAN ORANGE MODE: By adding another gain stage after the tone stack we get a punchier sound that’s easy to overdrive. As in the rest of the modes the channel’s VOLUME control is now active.
- CLEAN RED MODE: This mode pushes the original clean sound even more and trans-forms into a pseudo high gain channel with the addition of yet another gain stage after the tone stack.In keeping with the classic clean amps of yesteryear, all three modes on this channel feature what is known as a pre-gain tone stack (i.e. the tone network lies before the channel’s main gain stage). The reverse (i.e. the tone network being after the main gain stage) is typical of most Marshall amplifiers and, as a result, the CLEAN channel’s tone controls work in a slightly different way than you might expect; in addition to controlling the tone of the channel they also affect how it reacts in terms of gain, allowing you to shape how the signal distorts. For example, turning up the MIDDLE control on higher GAIN settings will focus the distortion there, making your sound ‘sing’ in a traditional blues/rock way. Also, because of the channels’ ‘tone then gain’ topology, when a lot of GAIN is dialled in (especially in the case of the red mode), it may appear that its tone controls aren’t doing as much as you’d expect or sound over distorted. This is because the signal is being distorted after the tone stage, minimising the effectiveness of the BASS, MIDDLE and TREBLE controls.
- CRUNCH CHANNEL: At this point JVM4 reverts to the more typical Marshall preamp circuit characteristic of ‘gain then tone’. This is also true of the OD1 and OD2 channels.
- CRUNCH GREEN MODE: This mode shares the preamp topology of the classic Mar-shall JTM45/1959 Plexi™ models (i.e.: gain + gain + tone) but with a bit more gain than is found in the originals.
- CRUNCH ORANGE MODE: This mode is reminiscent of the JCM800 2203 amplifier, a staple of hard rock. The gain structure is gain + gain + gain + tone.
- CRUNCH RED MODE: This shares the topology of the orange mode, but with more gain, giving you sounds similar to a hot-rodded JCM800.
- OD1 GREEN MODE: This is very similar to the hot-rodded JCM800 sound found in crunch red mode, allowing you to dial-in two distinctly different yet similar crunch sounds if you so wish - one in each channel.
- OD1 ORANGE MODE: This adds another gain stage to the OD1 green mode, resulting in a sound that’s perfect for singing leads and hard rock/heavy metal tones.
- OD1 RED MODE: Adds more gain to the OD1 orange for a high gain Marshall sound.
- OD2 CHANNEL: This channel is similar to the OD1 channel but with even more gain and a slightly different tone network with the middle control shifted down to being centred around 500hz instead of the more typical Marshall value of 650hz. The result is 3 high gain modes that are ideal for both lead and modern rhythm metal tones. |
