The Catalinbread Dirty Little Secret Deluxe was covered by Delicious Audio on September 22, 2023, and by Gearnews on September 7, 2023. It is an expanded version of the company's Catalinbread Dirty Little Secret MK III, which Gearnews describes as the standard model1.
Catalinbread says the pedal is an all-discrete circuit with a preamp, phase inverter, power amp sim and output transformer2. The maker states the original DLS circuit was tweaked and upgraded throughout, and that the Deluxe began as a fourth version of the flagship pedal before becoming the Deluxe2. Gearnews reports the Preamp control has a wider gain range, with more cleans and more dirt1.
Controls are Master, Preamp, Presence, Treble, Middle and Bass, plus a Boost Volume mini-dial and an SB/SL mini-toggle1. The Presence knob, formerly an internal trimmer, is now external21. Catalinbread says it is a low-pass filter that attenuates frequencies by 3dB above 1.59KHz when turned all the way down2. The toggle selects between Super Lead and Super Bass modes, which Catalinbread describes as a cutting, upper-midrange-heavy tone and a smoother, smokier tone with lower midrange emphasis2. Gearnews reports the three-band EQ is passive and highly interactive1.
A built-in footswitchable boost, modeled after a clean Marshall preamp, can run before or after the DLS circuit via an internal switch2. Catalinbread ships the pedal with the boost before the DLS2. A Tightness control is an internal high-pass filter that cuts up to about 230Hz at maximum2; Gearnews also describes it as internal1. A rear-panel Line Out gives a dedicated +10dB output for a mixer or DAW, and both outputs can be used at once2. The pedal has top-mounted jacks1 and buffered bypass2. It runs on a center-negative 9-volt supply drawing at least 7mA2.
Premier Guitar lists the price at $299.993; Gearnews gives an MSRP of USD 2991.
"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."
