Description :

Classic, Marshall Valvestate 100V Model 8100 is a highly regarded hybrid amplifier head, known for its association with metal guitarists in the 90s.

•  Hybrid Design: The "Valvestate" technology is Marshall's approach to blending the cost-effectiveness and reliability of solid-state circuitry with the warmth and harmonic response of a single 12AX7 (ECC83) preamp tube. This tube is strategically placed in the gain stage to add tube character, especially to the overdrive channels. * Channels:
• Clean Channel: Offers pristine clean tones with independent volume, bass, middle, and treble controls.
• Overdrive Channel (OD1/Crunch): Provides a classic Marshall crunch sound, suitable for rock and blues. Shares a 3-band EQ (bass, middle, treble) with OD2.
• Overdrive Channel (OD2/Lead): Delivers aggressive, high-gain distortion, making this amp famous in metal genres. Shares an EQ with OD1 and features a "Contour" control.
• Contour Control: This is a distinctive feature, particularly for the overdrive channels. It allows for significant mid-sculpting, ranging from a mid-boost to a heavily scooped (V-shaped) mid-range, popular for tight, modern metal tones.
• Effects Loop: Includes a send and return for external effects pedals, often with a mix control.
• Spring Reverb: A built-in spring reverb unit provides classic ambient effects.
• Master Volume: A master volume control for overall output.
• Measures 23" x 10" x 8"

The Marshall Valvestate 100V Model 8100 is a legendary amplifier head that carved its niche in the 1990s, particularly among metal and hard rock guitarists seeking powerful, articulate high-gain tones. As a "hybrid" amplifier, it cleverly combines the robust and consistent performance of a solid-state power section with the tonal characteristics of a 12AX7 preamp tube, offering a unique sonic footprint.

Renowned for its versatility, the 8100 provides two distinct channels: a clean channel capable of delivering clear and vibrant tones, and an overdrive channel that can be switched between a classic Marshall crunch (OD1) and a ferocious, saturated lead tone (OD2). The "Contour" control on the overdrive channel is a key element, allowing players to dial in everything from thick, mid-rich sounds to extreme scooped-mid aggression, perfect for tight rhythm guitar in heavy music.

While initially seen by some as a more affordable alternative to all-tube amps, the Valvestate 8100 has gained a cult following in recent years. It's raw power, distinctive high-gain character, and association with influential bands like Death (Chuck Schuldiner famously used this amp) have elevated it's status to a sought-after piece of gear for those chasing authentic 90's metal tones or a unique hybrid voice. It's a workhorse amp capable of delivering ample headroom for live performances and impactful tones in the studio.
