The Horizon Amp Overdrive is a faithful recreation of the Catalinbread Dirty Little Secret Mk I, which is known for its amp-like response and Marshall flavor. The DLS Mk I is considered by many to be the best version of the pedal, with subsequent versions being quite different in terms of tonestacks and tweakability.

The DLS circuit utilizes cascaded mu-amps as its foundation, without the use of op-amps or clipping diodes. Instead, the clipping signal is generated solely by the JFETs, resulting in a unique flavor compared to overdrives that rely on diode-clipping.

Overall, the Horizon Amp Overdrive aims to capture the distinctive characteristics of the Catalinbread Dirty Little Secret Mk I, providing guitarists with a versatile and authentic Marshall-like overdrive experience.
