This mod makes your boss BD-2 sound fantastic . . . at about 12 o'clock on the gain dial you get a bang on marshall plexi sound, 9 o'clock you get beautiful edge of breakup. Everything about this pedal becomes sexier . . . and it's very easy to do!
I ran across this info on the internet about 6-7 years ago . . . it originally came from Robert Keeleys website. (It was one of the many mods that he did on the BD-2s . . . before he stopped sharing his secrets) I posted in a BD-2 review on Harmony-Central too, but I figured that you guys might like it.
D3 -> Change this 1SS133 to a different (1N4002) diode for asymmetrical clipping. This adds second order harmonics. This adds to the tube type sound. I like the sound of this change.
D7 and D10 -> Change these diodes from 1SS133 to 1N4002. More second order harmonic distortion. Although the change is slight, I like it.
C1, C7, C6, C12, C13, and C15 -> Change this electrolytic capacitor to a 10uF tantalum. Tantalum capacitors sound better than electrolytic capacitors. It would be best to have a non-polarized cap here. I like these anywhere there is signal coupling at this high a value. Tantalum capacitors are easy to find in this range.
C14 -> Increase input coupling capacitor value to 0.1uF for increased bass response from your guitar.
R1, R2, R18 and R19 -> Here is some magic. Change the resistors to carbon composition. These old resistors probably have some frequency dependent component, which means that there is a capacitive element to the resistor. This is because of the spacing in the material. Add these for vibe, MOJO, and magic.
C100 -> Here is where we can affect the tone control. I prefer a little more lower-midrange and bass frequencies through the tone section. You can increase the lower frequencies by increasing the capacitor value to 0.033uF. |

| Might be a little while, as I don't have a good mic, but I'll see what I can do . .. |

OK . . . This definatley doesn't show off the full power of the ole modded pedal, as i'm running it into my little 2X10 solid state practice amp (the toob amp is in hte shop). I should mention that I like my amp to be a little bright to cut through when I solo, so keep that in mind. I usually play with a little delay on ( I had a very little on for the first song but then decided to take it off and do the other clips completely dry . . .) The BD-2 sounds best in a full band situation where it really sounds great IMO. Anyhoo, here it is:

PS - Please excuse the playing . . .
PPS - I sold my non modded BD-2 so maybe someone else can give us a clip? |
