the pedal sounds fantastic. saturation is creamy, little emphasis on mediums but sparkly and with MOD on bassy enough. Could be the only overdrive you'll actually need, and this is truer than ever BECAUSE.. because despite the buffered bypass, despite the modern construction, won't accept well anything before it. I've put several pedals upstream, true bypass or not, and the result is a little but evident loss in the highs on the Centavo. even true bypass pedals set to off do this. If you own two pedals that have this syndrome (i have several) you're stuck, in my case a fuzzface wants to be first, if i do so the Centavo results to be less sparkly, acceptable, but you won't get 100% from it. If i put the fuzzface after it, the fuzzface sounds oversaturated and unacceptable. So: put pedals after it, if you can.
