Demo of the Reuss Musical Instruments Swiss Army Knife dual overdrive.

My take:
The Swiss Army Knife is Reuss' take on 2 classic overdrives - the ProCo RAT (distortion side) and the Klon Centaur (overdrive side). I found the distortion side to be very "RAT-y" – bright, spitty, dirty, classic distortion. The Klon side was also very familiar sounding, but maybe a little tighter and also ballsier, with a bit more low end push. Both together were hugely saturated and sustained basically forever! :-) A really FUN pedal to play with. Get one!
