The team over at Aclam have a great ear for re-producing amp like tones in a pedal. They've done this by following amp circuits and swapping out the Valves/Tubes for FETs which behave in a very similar way but are much smaller. On the Cinnamon drive however the aim wasn't to replicate a single amp, instead its the sound of an era. The 60's and 70's saw the likes of Hendrix, Clapton and many many more pushing their amps like never before, so by using a mixture of a soft clipping circuit as the main tone and a hard clipping circuit in the boost section you can recreate your favourite classic rock tones to an epic degree!
