Keeley type bd-2 mods: Wow!

[mstoppini]

Hi,

I've just finished enjoying my 'new' Blues Driver, after these mods:
- 1 1n4007 in place of D3
- 1 1n4007 in place of D7+D8
- input cap to 0.1 uF
- tone cap to 0.033 uF

Geez, the best overdrive I've ever had!
A really nice crunch sound, very inspiring, and with the guitar volume control a wide variety of clean-to-growl sound.
Best of all, putting my modded (a 1n4007 in place of one of the diode of the back to back common pair)  DS-2 in front of the BD-2 there is a waterfall of boiling saturation, but still very intelligible!
I think I'll be satisfied with this setup for a long time.
Thank you all, my friend, to let this forum live.

I tweaked my BD-2 last night with 1N4001s in the typical spots.  Question:  Do the different 1N400X diodes sound different from each other?  I've got two BD-2s and after installing 1N4001s and upgrading a few caps + adding a 1N34 to D1 - I A/B'd the two Modded VS Stock and could barely tell a difference.  I was playing at bedroom level and was not able to push the amp at all (6L6s) - so maybe this is the issue; I don't know.  I did increase C14 in value to .1uF and C100 to .033uF as well.

Any thoughts on using a different diode from the 1N400X series?  I'd like to get some input to save myself extra work of parts swapping.

Thanks.

I couldnt find anything on the Search. Where do you find the info for this
Keeley mod?

as far as clipping is concerned, you won't hear a difference from a 1n4001 to any other 1n400x type diodes generally.
