There is no "best" pedal. So much depends on personal taste. My setup: a Vox Cooltron Over The Top Boost and an AC15CC1. I use the pedal as a poor man's 2nd channel (clean on the AC15 and add whatever overdrive I want with the pedal). Or I use the pedal as a clean boost with tone controls (turn the Volume up on the amp to get overdrive and then use mainly Volume on the pedal with a little Gain). Same effect as a treble booster, but with more control over the tone. The Tone Cut on the pedal can be used to get rid of "hiss" way at the top end ... "hiss" that's typical of a treble booster. What sounds great to me, you may not like. Follow your own instincts.
