The BD-2 Phat Mod is Transparent Overdrive with Full Range sound.
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.
