Mine is undoudbtedly my zvex super super 2 in 1. One stage of it is on all the time and it just extracts all the goodness and sparkle out of my amp and pickups. Second stage is the perfect boost, subtle or completely nasty! I have tried countless boutique overdrive/distortion/fuzzes on all ends of the price spectrum and, although some have been great pedals, nothing beats my orange ad30htc cranked even further by my zvex super duper 2 in 1. It is the only untouchable item on my pedalboard! And please - no tuners!
