I rather want to stack like in a traditional way (Overdriven amp + OD pedal) maybe because my amp is a bit gainy. For what i've tried before, I really love the combination of Boss OD-3 + Boss BD-2, cause it sounds classic to me like no other, and it doesn't sound like a marshall, vox, mesa etc. Emulation of anything else is not my priority, but to create my very own signature tone.
