Catalinbread Dirty Little Secret Deluxe

The Dirty Little Secret Deluxe takes Marshall Plexi-style emulation to the next level by recreating not just the preamp, but the entire amplifier circuit—from the phase inverter to the output transformer—for a stunningly realistic amp-in-a-box experience. Building on the foundation of the beloved DLS circuit, the Deluxe version adds key upgrades including Super Lead and Super Bass modes, a front-panel Presence control (low-pass filter), and an internal Tightness control (high-pass filter) for shaping low-end response. A dedicated Line Out with +10dB output allows easy integration with recording setups or IR loaders.

What sets the DLS Deluxe apart is the built-in single preamp tube simulator, which functions as an independent boost circuit. Thanks to the internal Effect Order switch, you can place the boost before or after the main drive circuit—stack it in front for extra gain and saturated JCM900-style tones, or run it after to elevate your volume without losing clarity. With a responsive Master and Preamp control, classic 3-band EQ, and the flexibility to tailor your gain structure, the Dirty Little Secret Deluxe is a complete, pedal-sized Marshall stack with all the touch, roar, and nuance of the originals.
