Marshall JVM410H 100W Valve Amp Head
The Flagship Marshall Amp, Combining Modern Functionality With Classic British Valve Tone
The flagship JVM series has been a part of Marshall's catalogue for over a decade; testament to the popularity and versatility of these modern all-valve amplifiers. As the most comprehensive models ever made by the British company, JVM amps are aimed at professionals who seek ultimate performance and flexibility.
The 100W JVM410H is a mightily powerful amp head; the king of the JVM range. Boasting 4 channels, this amp also features a speaker-emulated output, built-in digital reverb, MIDI capability and series/parallel effects loops for seamless use with guitar pedals.
3 Modes Per Channel - 12 Amp Sounds In Total!
A 4-channel amp is already a monster, letting you easily switch between clean, crunch, distorted and lead sounds. But sometimes, it's nice to have even more tonal options at your disposal. That's why Marshall designed its JVM amps with multi-mode functionality, giving you 3 different sounds per channel for 12 amp tones in total!
The green, orange and red modes simply change the amount of usable gain, but also alter the character and response. Green mode provides the subtlest sounds, while the orange mode has increased gain for JCM800-like tones. Red mode really turns up the heat, giving you sizzling high-gain for heavier styles.
All of these modes can be accessed via the included footswitch. Simply choose your channel, and press the channel select switch again to flick between green, orange and red modes. The footswitch also remembers the last modes that you engaged, making the JVM great for live use.
The JVM410H is powered by a quartet of classic EL34 power tubes. Synonymous with the unmistakable British amp sound, EL34s break up softly to create tight, saturated and harmonically-rich tones.
If you're concerned about this amp not sounding good at low volumes though, you needn't worry! You can simply keep the master volume low and drive the ECC83 preamp tubes (via the channel volume controls) to attain those authentic cranked valve amp tones at bedroom levels.
Each of the JVM410H's channels feature independent 3-band EQ sections, meaning that you can precisely tweak your ideal clean, crunch, distorted and lead tones. The master presence and resonance knobs let you affect the overall highs and lows to suit the acoustic characteristics of any space or venue.
Assignable digital reverb per channel is also useful, and you can even set different reverb levels if you want a wet ambient clean sound and a drier distorted tone. The JVM's two effects loops not only allow you to use external modulation and time-based pedals, but with a thoughtful mix control too, you can affect their volume in the signal chain.
One of the coolest features on a Marshall JVM amp is the second master volume control. Letting you set a different amount, you can engage the second master volume via the included footswitch to give your solos an extra boost!
All Marshall JVM amps feature MIDI inputs, meaning that you can use external MIDI controllers to switch their channels completely on the fly! If you use a pedalboard switcher with a MIDI interface, you can therefore control all of your stompboxes and simultaneously send MIDI commands to a JVM amp.
With the ability to change other parameters via MIDI, such as the JVM's built-in reverb, second master volume and effects loop; this amplifier is truly built for contemporary players looking for ultimate control!
