I'd like to be able to get a thicker tone from the higher pitched strings on my strat, but keep the lower strings fairly clean and tight. Is this possiblke, and if so, what kind of pedal? Treble boost? I know a traditional fuzz seems more the opposite, lots of low end but highs stay fairly sharp (like my dano cool cat fuzz, great pedal, but not really what I'm going for.) Any suggestions?
