11 Years of Boutique Tone from one of the best overdrive sounds Boss created. The Keeley mod has been used on dozens and dozens of chart topping songs.
KEELEY BD-2 MOD IS A TONE MONSTER! Used by John Mayer, Steely Dan (Jon Herrington!), Brad Paisley and even The Edge of U2!
The BD-2 Phat Mod is Transparent Overdrive with Full Range sound. Honestly one of the neatest sounds ever put in a stomp box.
For tone-purists, this is it! It's not simply a distortion pedal but rather a tone tool that adds to your guitar tone, supplying really nice lows, crystal clear high frequency, great picking response and detail. For those wanting to set their amp on fire but not change the tone of their system, this is the pedal.
The BD-2 is not the same as a TS9 pedal. It has a more FULL-RANGE sound and is much more TRANSPARENT. When cranked it offers a grittier/more-edgy tone.
