There are hundreds of glorifying reviews and fantastic demos online and on YouTube. Here are a couple to whet your whistle: https://www.youtube.com/watch?v=HEVGdhpIIos , https://www.musik-produktiv.com/gb/gurus-1959-double-decker.html
The Gurus 1959 Double Decker is a wildly versatile preamp pedal with two distinct drive channels and a separate solo boost, essentially one-stop shopping for all things vintage British overdrive and distortion.
With lower-gain Blues breaker crunch on "Floor 1" and the sound of a maxed out Plexi on "Floor 2", each with its own independent tone stack, the 1959DD also features a direct output that's switchable between the dry direct sound and a mic'd speaker emulation that's amazing for going straight to front-of-house or your DAW. Rounded out by a tube effects loop with series/parallel switching and remote connections for analogue switchers, the 1959 Double Decker is quite the impressive offering.
