Can anyone help me? Boss SD-1 mod problem

[ledvedder]

I tried modding my SD-1, and I think I screwed something up.  I tried a combination of a few different mods.  Now, when I'm using it, the signal is much weaker than if I remove it out of my chain and run it directly into my amp.  When I'm going through it, and it's not active, the clean sound is muddy and a little quieter.  Here's what I changed.

Replace the 1uF cap at C10 with a 10uF cap
Removed C6
Replaced D4, D5, D6 with 1N4001 diodes
Changed C3 from .047uF to .1uF
Changed R2 to 1M
Changed R18 and R19 to 10K

What did I screw up?

Three threads for one pedal? 

R2 is an input impedance mod and therefore would affect both clean and dirty signal paths. Check that it really is a 1M resistor and that your soldering hasn't caused any bridges. Check for bridges around the other parts you replaced too.

Other than that, do all the other changes look good?

[anchovie]

All the other changes are for components in the dirty path, so therefore should not cause the problem you describe when the pedal is in bypass.
