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.
Want the best overdrive for BASS? Try the Blues Driver! A TS9 or other bass drive pedal will just limit your low end response; this will make tube sounding bass-overdrive a reality for you.
The parts added will increase the warmth of the pedal and add a level satisfaction to your playing. Film capacitors are used in the tone section to provide the smoothest midrange and high frequency components to your tone while increasing the bass response of the pedal.
This pedal has been modified to have slight asymmetrical clipping. This mod gives you 2nd order harmonic distortion. This has a very musical sound. At very high saturation levels it almost becomes an octave type of sound effect.
If your unit has been modified to have the PHAT Switch, moving the switch up engages this tone. There is a slight bass increase felt when notes are played on the open E and A strings. Strum those strings while moving the switch back and forth to get an initial feel of the possibilities. It might be a good idea to turn the Phat switch off under really loud situations if there is too much low end in your sound.
