New Catalinbread Dirty Little Secret Deluxe Overdrive Guitar Effects Pedal

From Catalinbread:

The ultimate Marshall Plexi emulation and fully-customizable amp-in-a-box experience.

The Dirty Little Secret Deluxe represents the next logical step in Marshall Plexi emulation, reaching beyond the preamp circuit and adding the rest of the amp for an extremely authentic take on everything inside that chassis. Our original DLS circuit has been tweaked and upgraded throughout, now featuring a phase inverter, power amp sim and output transformer as well as some new features and the most requested modifications for the original. One such addition is a toggle switch on the outside to select between Super Lead and Super Bass modes, and we've also externalized the Presence knob to easily dial in your preferred Marshall flavor. Also added is a piece of the Dirty Little Secret—a single preamp tube simulator—as a built-in boost circuit that can be used independently of the main circuit. You can run the boost and DLS in any order you like; put the boost before the DLS for a high-powered saturated tone or after to pummel the front end of your amp. A new tightness knob lets you shave off the sub-bass for a little extra clarity or completely attenuate the low end for some cool thrash metal tones. A Line Out jack gives you a dedicated +10dB output that you can use with a mixer or DAW, and you can use both outputs simultaneously.

Controls
MASTER: This knob occurs before the phase inverter and output transformer rather than at the end of the circuit, just like a real amp.

PREAMP: A wider gain range with more cleans on the lower end and more cranked Marshall tones on the higher end.

PRESENCE: A powerful low-pass filter that attenuates frequencies above 1.59KHz when turned all the way down.

BOOST / BOOST VOL: A tube emulation building block that makes up the DLS itself; run before the DLS for saturated JCM900 tones, or after to make everything louder without sacrificing clarity. Boost Vol is the volume control for the boost side.

TREBLE/MIDDLE/BASS: Classic Marshall amp tone stack values, highly interactive. Passive tonestack, so noon is not flat. Values swap when switching modes.

SL/SB TOGGLE: Switch between Super Lead mode (cutting, upper-midrange-heavy) and Super Bass mode (smoother, smokier, lower midrange emphasis).

Under the Hood
TIGHTNESS: Bass attenuation via a subtle high pass filter, cutting up to ~230Hz at maximum.

EFFECT ORDER: Reroutes the order of the boost and the DLS circuit.

LINE OUT: Rear panel dedicated +10dB output for direct recording or mixing; usable simultaneously with the standard output.

Power Supply
The Dirty Little Secret DLX accepts a center-negative DC power supply capable of supplying 9 volts and at least 7mA of current (not included).
