Just out of interest :
I've sold quite a few DS1/SD1/BD2/TS9's with various improvements for the last three years
I've just got a new "batch" of DS1's in for "upgrading" and use similar tweaks with a few
specific changes.
Comparing to a new "unchanged" one is something that I do a lot, and these kind of changes
including using either LED's or 1N4001's for diodes, produce an overall output level of around
twice the volume of an unmodded one !!
This is with tone/vol/gain all at 12 o'clock and using an A/B box to route to them rather than
in series ( though that is probably just as good )
Not only does this mean that it will "kick" an amp quite nice, also you can keep the levels down
and still be as "loud" as a stock pedal and the noise floor seems better also because of this.
Good stuff

MM.
