The Tsakalis Audioworks Room #40: Legendary Marshall™ Amp Tones in a Compact Pedal

Iconic British Amp Sounds Captured

The Tsakalis Audioworks Room #40 faithfully recreates the legendary tones of classic Marshall™ amplifiers in a compact, pedalboard-friendly format. Using advanced JFET technology, this pedal captures the essence of the PLEXI™ Super Lead, Super Bass, JMP™, and JCM800™ amps, delivering authentic British crunch, compression, and sag. Perfect for players chasing the "brown sound" and beyond, the Room #40 brings the mojo of vintage amps to your rig.

Two Iconic Circuits with Custom Mods

The Room #40 offers two distinct Marshall-inspired circuits:

• PLEXI™ (19): Delivers the rich, dynamic tones of the non-master volume series amps, including the Super Lead and Super Bass.
• JMP™ & JCM800™ (22): Captures the power and punch of the master volume series amps.

Both circuits feature two famous mods—Mod #39 (PLEXI™) and Mod #34 (JMP™/JCM800™)—for added tonal flexibility.

Variac Voltage Control for "Brown Sound"

Inspired by Eddie Van Halen's iconic tone, the Room #40 includes a Variac voltage control knob that adjusts from 7.5V to 21V, allowing you to emulate the dynamic response and sag of amps pushed to the edge.

Enhanced EQ and Presence Controls

The Room #40 features a classic Marshall™-style three-band EQ (Bass, Middle, Treble) and a versatile Presence control. These allow you to tailor your tone for darker or brighter amps and ensure compatibility with any setup, from front-of-amp connections to direct power amp usage.

• Gain Boost: Engageable via a footswitch with a dedicated trimmer for fine-tuning.
• True Bypass: Preserves your signal when the pedal is disengaged.
• Durable Construction: Handmade in Athens, Greece, with a lightweight aluminum enclosure designed for road-ready reliability.
