Seller's description

The Catalinbread Dirty Little Secret Deluxe is dedicated to all things Marshall. It features an all-discrete circuit with a preamp, phase inverter, power amp sim and output transformer. The built-in footswitchable boost modeled after a clean Marshall preamp and effect order switch gives you a fully-customisable amp-in-a-box. Controls: MASTER: This knob comes before the phase inverter and output transformer rather than at the end of the circuit, just like a real amp. The output stage tis designed to be more impervious to input saturation than most power sections, so cranking it doesn’t alter the tone in a very noticeable way. However, those that plan to use the DLS DLX as an always-on can find some subtle sag and gentle compression living within the whole of the volume knob. PREAMP: The original preamp control has been tweaked to deliver a wider gain range with more cleans on the lower end and more cranked Marshall tones on the higher end. PRESENCE: Formerly an internal trimmer on the original, the Presence control is a powerful low-pass filter that attenuates frequencies by 3dB above 1.59KHz when turned all the way down, and the cutoff point climbs to an indistinguishable frequency by the end of the turn. BOOST: When you run the boost before the Dirty Little Secret it acts as another “preamp tube” added to the front end of the device for some saturated JCM900 tones. When its run after, it makes everything louder without sacrificing clarity. WARNING: please see note in “Effect Order” section below. BOOST VOL: When you run the boost before the Dirty Little Secret, it acts as another “preamp tube” added to the front end of the device for some saturated JCM900 tones. When its run after, it makes everything louder without sacrificing clarity. This knob is a volume control for the Boost side, so at lower points in the knob’s turn, the boost signal can get below unity gain. This helps you dial in maximum tone shaping for combining the two effects. TREBLE/MIDDLE/BAS
