Product Overview
The JCM900 4100 is a two-channel, dual spring reverb 100W powerhouse designed to make you stand out on any stage. As the natural evolution of the JCM800, this stylish reissue adds more gain, more versatility, and more features for the modern performer. Designed, engineered, and built in the UK, the JCM900 was created to go on the road and fill stadiums with its high-gain roar and crystalline cleans.
Product Description
The Evolution of a Legend: While the JCM800 defined the 80s, the JCM900 took over the 90s. It offers a dual-channel architecture, providing a dedicated Channel A for sparkling cleans and classic crunch, and a high-gain Channel B for searing leads and aggressive distortion.
Dual Reverb Controls: Unlike its predecessors, the 4100 features independent spring reverb controls for each channel. This allows you to add a subtle wash to your rhythm playing while drenching your lead lines in lush, vintage-style space.
High-Gain Mastery: With two gain features, this amp provides that extra boost needed for modern rock and metal. Channel B (Lead Gain) is capable of extreme saturation, ensuring your solos have the sustain and harmonic richness required for the big stage.
Versatile Power: To suit different playing environments, the 4100 features a power reduction mode. You can switch from a massive 100W down to 50W at the flick of a switch, allowing the four 5881 power valves to break up earlier for a smoother response.
Built-in Precision: Handcrafted in Marshall’s UK factory, this all-valve head includes a series FX loop with level control, allowing you to integrate your outboard effects perfectly regardless of your gain settings.
Key Features
Dual Channel Layout: Foot-switchable channels for instant transitions between clean and dirty.
5881 Power Valves: Known for their durability and "glassy" top-end, providing a distinct tonal flavor compared to standard EL34s.
Comprehensive EQ: A shared 4-band EQ (Treble, Middle, Bass, Presence) allows for precise tone sculpting across both channels.
Stage-Ready Connectivity: Dual speaker outputs with selectable 4Ω, 8Ω, or 16Ω loads to match any professional cabinet.
